Below is the default configuration for the emulator. Not all options mentioned below are mandatory. For example, options such as Resolution Scale and Anisotropic Filter can be increased if your graphics card can handle the additional load whereas Approximate xfloat should be disabled with weaker CPUs on games that will work fine without it. If the game has graphical glitches, you may also need to enable Write Color Buffers or Read Color Buffers to fix them. For best performance, read the description for each option carefully and also refer to the specific configurations mentioned for each game page.

CPU configuration

Setting Default Option Description
PPU decoder LLVM Recompiler LLVM Recompiler: Recompiles the game's executable once before running it for the first time. By far the fastest option and should always be used. Should you face compatibility issues, fall back to one of the Interpreters and retry.
Interpreter (dynamic): May be faster than static interpreter. Try this if PPU LLVM Recompiler doesn't work.
Interpreter (static): This is the most accurate option. Interpreter (slow). Try this if PPU Recompiler doesn't work.
SPU decoder LLVM Recompiler LLVM Recompiler: Fastest option with very good compatibility. Recompiles the game's SPU LLVM cache before running which adds extra start-up time. If you experience issues, use the ASMJIT Recompiler.
ASMJIT Recompiler: Fast option with very good compatibility. If unsure use this option.
Interpreter (dynamic): May be faster than static interpreter. Try this if SPU Recompiler (LLVM) and ASMJIT doesn't work.
Interpreter (static): Slowest option. Try this if SPU Recompiler (LLVM), ASMJIT, and Dynamic do not work.
SPU XFloat Accuracy Approximate XFloat Control accuracy to SPU float vectors processing.
Fixes bugs in various games at the cost of performance.
This setting is only applied when SPU Decoder is set to Dynamic or LLVM.
Enable SPU loop detection Off Try to detect loop conditions in SPU kernels and use them as scheduling hints.
Improves performance and reduces CPU usage. May cause severe audio stuttering in rare cases.
Increase AVX-512 instruction width Off Enables the use of code with full width AVX-512.
This code can be executed much faster, but may cause a loss in performance if your CPU model experiences downclocking on wide AVX-512 loads.
Note that AVX-512 instructions will be used regardless of this option, just at 128 and 256 bit width.
Only available with CPUs that support AVX-512.
Max Power saving CPU-preemptions 0 Reduces CPU usage and power consumption, on mobile devices improves battery life. (0 means disabled)
Higher values cause a more pronounced effect, but may cause audio or performance issues. A value of 50 or less is recommended.
This option forces an FPS limit because it's active when framerate is stable.
The lighter the game is on the hardware, the more power is saved by it. (Until the preemption count barrier is reached)
TSX instructions Enabled Enable usage of TSX instructions.
Needs to be forced on some Haswell or Broadwell CPUs. Forcing this on older Hardware can lead to system instability, use it with caution. Also needs to be forced if TSX-FA is detected.
SPU block size Safe This option controls the SPU analyser, particularly the size of compiled units.
Mega and Giga modes may improve performance by tying smaller units together, decreasing the number of compiled units but increasing their size.
Use the Safe mode for maximum compatibility.
Preferred SPU threads Auto Some SPU stages are sensitive to race conditions and allowing a limited number at a time helps alleviate performance stalls. Setting this to a smaller value might improve performance and reduce stuttering in some games.
Please note that the best value depends on the individual game and specific CPU being used, so users need to try different values themselves.
Leave this on Auto if performance is negatively affected when setting a small value.
Thread Scheduler Operating System Control how RPCS3 utilizes the threads of your system.
Each option heavily depends on the game and on your cpu. It is recommended to try each option to find out which performs the best. Changing the thread scheduler is not supported for CPUs with less than 12 logical threads.

GPU configuration

Setting Default Option Description
Renderer Vulkan Vulkan is the fastest renderer while OpenGL is the most accurate renderer. If unsure, use Vulkan.
Should you have any compatibility issues when using Vulkan, fall back to OpenGL.
Graphics device NA On multi GPU systems select which GPU to use in RPCS3 when using Vulkan. This is not needed when using OpenGL.
Aspect ratio 16:9 Leave this on 16:9 unless you have a 4:3 monitor.
Framelimit Auto Most games have a built in frame limit. By using RPCS3's framelimiter simultaneously with the game one you may only hurt performance. Setting the framelimit to Off is the best option as it performs faster.
Only use framelimiter if a game runs too fast without it. Some games may crash if the framerate is too high. If that happens, set value to anything other than Off.
Anisotropic filter Auto Modern GPUs can handle this setting fine, even at 16x. Keep this on Auto if you want to use the original settings used by a real PS3. May break some Unreal Engine games if set to anything except auto. Higher values increase sharpness of textures on sloped sufaces at the cost of GPU resources. If unsure give 16x a try.
Anti-aliasing Auto Emulates PS3 multisampling layout.
Can fix some visual artifacts in some games.
Low to moderate performance hit depending on your GPU hardware.
ZCULL accuracy Precise (slowest) Changes ZCULL report synchronization behavior. Experiment to find the best option for your game.
Precise is the most accurate to PS3 behaviour.
Approximate is a faster way to generate occlusion data which may not always match what the PS3 would generate.
Relaxed changes the synchronization method completely and can improve performance and break visual effects in some games.
Shader quality High Controls the precision level of generated shaders. Low precision generates much faster code depending on the hardware, but can sometimes generate minor visual glitches or flicker.
Default resolution 1280x720 In most cases, do not change resolution in settings, leave it at 1280x720. Any other setting may result in compatibility issues and performance decrease.
If you wish to try setting the resolution higher to 1920x1080, you MUST check the compatible resolutions for the game from the game list to ensure that it can support such a resolution.
Forcing such resolution on games that do not support it will result in significant issues.
Using resolutions lower than 1280x720 will not improve performance.
Resolution scale 100% Scales the game's resolution by the given percentage of the base resolution set in the above option. Set this value to 100% if you want to use the normal resolution.
Note that you can use keyboard arrow keys for precise changes on the slide bars.
Resolution scale threshold 16 x 16 Only framebuffers greater than this size will be upscaled. Increasing this value might fix problems with missing graphics when upscaling, especially when Write Color Buffers is enabled. Do not touch this setting if you are unsure.
Note that you can use keyboard arrow keys for precise changes on the slide bars.
FSR Disabled AMD FidelityFX Super Resolution upscaling filter. FSR will attempt to handle upscaling with a reduced VRAM usage for games that have high VRAM usage. May cause visual artifacts. Does not currently work with stereo 3D output or OpenGL at the moment. If unsure use Resolution scaler instead.
Shader mode Async (multi threaded) Legacy (single threaded): Disables asynchronous shader compilation. Fixes missing graphics while shaders are compiling but introduces severe stuttering or lag. Use this if you do not want to deal with graphics pop-in, or for testing before filing any bug reports.
Async (multi threaded): This is the recommended option. If a shader is not found in the cache, nothing will be rendered for this shader until it has compiled. You may experience graphics pop-in.
Async with shader interpreter: Hybrid rendering mode. If a shader is not found in the cache, the interpreter will be used to render approximated graphics for this shader until it has compiled.
Shader interpreter only: All rendering is handled by the interpreter with no attempt to compile native shaders. This mode is very slow and experimental.
Number of shader compiler threads Auto Number of threads to use for the shader compiler backend.
Only has an impact when shader mode is set to one of the asynchronous modes.
Write color buffers Off Enable this option if you get missing graphics or broken lighting ingame.
Might degrade performance and introduce stuttering in some cases.
Strict rendering mode Off Enforces strict compliance to the API specification. Might result in degraded performance in some games. Can resolve rare cases of missing graphics and flickering.
Overrides settings for Resolution Scale and Resolution Scale Threshold and enforces default values.
It is meant to disable all the shortcuts in the rendering path, and as such it trades speed and resolution options for the enhanced compatibility.
VSync Off By having this off you might obtain a higher frame rate at the cost of tearing artifacts in the game.
Stretch to display area Off Overrides the aspect ratio and stretches the image to the full display area. Useful for games that have an ultrawide (21:9 or 32:9) patch available.
Enable 3D Off Enables 3D stereo rendering.
Note that only anaglyph viewing is supported at the moment.
Disable vertex cache Off Disables the vertex cache. Might resolve missing or flickering graphics output. May degrade performance.
Multithreaded RSX Off Offloads some RSX operations to a secondary thread.
May improve performance for some high-core processors. May cause slowdown in some situations due to the extra worker thread load.
Asynchronous texture streaming Off Stream textures to GPU in parallel with 3D rendering.
Can improve performance on more powerful GPUs that have spare headroom.
Only works with Vulkan renderer.

Audio configuration

Setting Default Option Description
Audio output Cubeb Cubeb is the recommended option and should be used whenever possible.
Windows: XAudio2 is the next best alternative.
Linux: PulseAudio is the next best alternative.
Audio format Stereo Determines the sound format.
Configure this setting if you want to switch between stereo and surround sound.
Changing these values requires a restart of the game.
The manual setting will use your selected formats while the automatic setting will let the game choose from all available formats.
Convert to 16-bit Off Uses 16-bit audio samples instead of default 32-bit floating point. Use with buggy audio drivers if you have no sound or completely broken sound.
Dump to file Off Saves all audio as a raw wave file. If unsure, leave this unchecked.
Music handler Qt Currently only used for cellMusic emulation.
Select Qt to use the default output device of your operating system.
This may not be able to play all audio formats.
Volume 100% Controls the overall volume of the emulation. Values above 100% might reduce the audio quality.
Note that you can use keyboard arrow keys for precise changes on the slide bars.
Enable buffering On Enables audio buffering, which reduces crackle and stutter but increases audio latency (requires Cubeb or XAudio2).
Audio buffer duration 100ms Target buffer duration in milliseconds. Higher values make the buffering algorithm's job easier, but may introduce noticeable audio latency.
Note that you can use keyboard arrow keys for precise changes on the slide bars.
Enable time stretching Off Reduces crackle and stutter further, but may cause a very noticeable reduction in audio quality on slower CPUs.
Requires audio buffering to be enabled.
Time stretching threshold 75% Buffer fill level (in percentage) below which time stretching will start.
Note that you can use keyboard arrow keys for precise changes on the slide bars.
Microphone type Null Standard should be used for most games.
Singstar emulates a singstar device and should be used with Singstar games.
Real Singstar should only be used with a REAL Singstar device with Singstar games.
Rocksmith should be used with a Rocksmith dongle.

I/O configuration

Setting Default Option Description
Keyboard handler Null Some games support native keyboard input. Basic will work in these cases.
Mouse handler Basic Some games support native mouse input. Basic will work in these cases.
Move handler Null PlayStation Move support is not implemented, leave this on null.
Fake: Experimental! This maps Move controls to DS4 controller mappings.
Path handler mode Single-threaded Single-threaded: All pad handlers run on the same thread sequentially.
Multi-threaded: Each pad handler has its own thread.
Only use multi-threaded if you can spare the extra threads.
Enable background input On Allows pad and keyboard input while the game window is unfocused.
Show PlayStation Move cursor Off Shows the raw position of the PS Move input.
This can be very helpful during calibration screens.
Camera input Unknown Depending on the game you may need to select a specific camera type.
Camera handler Null select QT to use the default camera device on your Operating System.
Camera Default Select the camera that you want to use during gameplay.
Camera Flip No Flips camera either Veritcally, horizontally, or both.
Buzz! emulated controller Null (use real Buzzers) Select 1 or 2 controllers if the game requires Buzz! controllers and you don't have real controllers.
Select Null if the game has support for DualShock or if you have real Buzz! controllers.
DJ Hero Emulated Turntable Null Emulates a DJ Hero Turntable. Not needed if you have a real turntable or the game supports DualShock controllers. You can use emulated turntables at the same time as real turntables.
Guitar Hero Live emulated guitar Null Emulates a Guitar Hero Live controller, Not needed if you have a real Guitar Hero Live controller or the game supports DualShock controllers. You can use emulated guitars at the same time as real guitars.

System configuration

Setting Default Option Description
Console language English (US) Some games may fail to boot if the system language is not available in the game itself. Other games will switch language automatically to what is selected here.
It is recommended leaving this on a language supported by the game.
Console region America The console region defines the license area of the PS3.
Depending on the license area, some games may not work.
Enter button assignment Enter with cross The button used for enter/accept/confirm in system dialogs. You can change this to use the circle button instead, which is the default configuration on Japanese systems and in many Japanese games.
In these cases, having the cross button assigned can often lead to confusion.
Clear disk cache automatically Off Automatically removes older files from disk cache on boot if it grows larger than the specified value. Games can use the cache folder to temporarily store data outside of system memory. It is not used for long-term storage.
Default wipe size is set to 5120MB.
Note that you can use keyboard arrow keys for precise changes on the slide bars.
Keyboard type English keyboard (US Standard) Sets the used keyboard layout. Currently only US, Japanese and German layouts are fully supported.
Console time Current time Sets the time to be used within the console. This will be applied as an offset that tracks wall clock time.
Can be reset to current wallclock time by clicking Set to Now.
Homebrew: Enable /host_root/ Off Required for some homebrew applications. If unsure, don't use this option.

Network configuration

Setting Default Option Description
Network status Disconnected If set to Connected, RPCS3 will allow programs to use our internet connection.
DNS 8.8.8.8 DNS used to resolve hostname by applications.
IP/Host switches DNS Swap List.
PSN Status Disconnected If set to Simulated, RPCS3 will fake PSN connection as best as it can. If set to RPCN, RPCS3 will use a Peer to Peer server connection to emulate online gameplay to the best of it's ability.

Advanced configuration

Setting Default Option Description
Debug console mode Off Increases the amount of usable system memory to match a DECR console and more.
Causes some software to behave differently than on retail hardware.
Accurate DFMA On Provides extra accuracy on FMA instructions at the cost of performance.
While disabling it might give a decent performance boost if your CPU doesn't support FMA, it may also introduce subtle bugs that otherwise do not occur.
You can't disable it if your CPU supports FMA.
Accurate RSX reservation access Off Forces RSX pauses on SPU MFC_GETLLAR and SPU MFC_PUTLLUC operations. Improves stability in some games but reduces performance.
PPU Non-Java mode Fixup On Legacy option, Fixup result vector values in Non-Java Mode in PPU LLVM. If unsure, do not modify this setting.
Accurate PPU Saturation Bit Off Accurately set Saturation Bit values in PPU backends. If unsure, do not modify this setting.
Accurate PPU Non-Java Mode Off Respect Non-Java Mode bit values for vector ops in PPU backends. If unsure, do not modify this setting.
PPU Vector NaN Fixup Off Fixup NaN resultsin vector instructions in PPU Backends. If unsure, do not modify this setting.
Accurate PPU vector NaN handling Off Accurately set NaN results in vector instructions in PPU backends. If unsure, do not modify this setting.
Accurate PPU Float Condition Control Off Accurately set FPCC Bits in PPU backends. If unsure, do not modify this setting.
PPU LLVM precompilation On Searches the game's directory and precompiles extra PPU modules during boot.
If disabled, these modules will only be compiled when needed. Depending on the game, this might interrupt the gameplay unexpectedly and possibly frequently.
Only disable this if you want to get ingame more quickly.
Delay each odd MFC command Off Forces delaying any odd MFC command, waits for at least 2 pending commands to execute them in a random order.
Must be used with either SPU interpreters currently.
Severely degrades performance! If unsure, don't use this option.
Silence all logs Off Stop writing any logs after game startup. Don't use unless you believe it's necessary.
Sleep timers accuracy Usleep only Changes the sleep period accuracy.
As Host uses default accuracy of the underlying operating system, while All Timers attempts to improve it.
Usleep Only limits the adjustments to usleep syscall only.
Can affect perfomance in unexpected ways.
Maximum number of SPURS threads Unlimited Limits the maximum number of SPURS threads in each thread group. May improve performance in some cases, especially on systems with limited number of hardware threads.
Limiting the number of threads is also likely to cause crashes. It's recommended to keep this at default value.
Clocks scale 100% Changes the scale of emulated system time.
Affects software which uses system time to calculate things such as dynamic timesteps.
Only available on per-game configurations.
Read depth buffers Off Initializes render target memory using vm memory.
Write depth buffers Off Writes depth buffer values to vm memory.
Read color buffers Off Initializes render target memory using vm memory.
Force disable exclusive fullscreen mode Off Forces borderless windowed mode for all fullscreen windows. Disables exclusive fullscreen graphics driver optimizations.
Use when you wish to stream using Vulkan or if your screen goes dim using HDR.
Note: RPCS3 does not use HDR at all.
Disable on-disk shader cache Off Disables the loading and saving of shaders from and to the shader cache in the data directory.
Allow host GPU labels (experimental) Off Allows the host GPU to synchronize with CELL directly. This incurs a performance penalty, but exposes the true state of GPU objects to the guest CPU. Can help eliminate visual noise and glitching at the cost of performance. Use with caution.
Vulkan queue scheduler Safe Determines how to schedule GPU async compute jobs when using asynchronous streaming.
Safe mode is spec compliant at the cost of some CPU overhead. This works with all devices.
Fast mode is faster but violates the Vulkan specification and is hacky. It is disabled on NVIDIA GPUs as it is known to cause GPU hangs.
RSX FIFO Accuracy Fast Fast is the least accurate setting, RSX does not emulate atomic FIFO buffer.
Atomic benefits stability greatly in many games with little performance penalty.
Atomic & Ordered is the most accurate option, but it is the slowest and without much stability benefit in games.
Driver wake-up delay 1 µs Try fiddling with this setting when encountering unstable games. The higher value, the better stability it may provide. 200μs and 400μs are good for most games.
Increments/Decrements for each test should be around 100μs to 200μs until finding the best value for optimal stability.
Values above this may cause noticeable performance penalties, use with caution.
Only available on per-game configurations.
VBlank frequency 60 Hz Adjusts the frequency of vertical blanking signals that the emulator sends.
Affects timing of events which rely on these signals.
Only available on per-game configurations.
VBlank NTSC Fixup Off Multiplies the rate of VBLANK by 1000/1001 for values like 59.94Hz.
Known to fix the rhythm game Space Channel 5 Part 2.
Only available on per-game configurations.

Debug configuration

Below configurations are primarily used by developers. If unsure, don't use these options.

Setting Default Option Description
RenderDoc compatibility mode Off Enables use of classic OpenGL buffers which allows capturing tools to work with RPCS3 e.g RenderDoc.
Also allows Vulkan to use debug markers for nicer Renderdoc captures.
If unsure, don't use this option.
Debug output Off Enables the selected API's inbuilt debugging functionality. Will cause severe performance degradation especially with Vulkan.
Debug overlay Off Provides a graphical overlay of various debugging information.
If unsure, don't use this option.
Log shader programs Off Dump game shaders to file. Only useful to developers.
If unsure, don't use this option.
Use high precision Z-buffer Off Only useful when debugging differences in GPU hardware.
Not necessary for average users.
If unsure, don't use this option.
Disable ZCull occlusion queries Off Disables running occlusion queries. Minor to moderate performance boost.
Might introduce issues with broken occlusion e.g missing geometry and extreme pop-in.
Force CPU blit emulation Off Forces emulation of all blit and image manipulation operations on the CPU.
Requires 'Write Color Buffers' option to also be enabled in most cases to avoid missing graphics.
Significantly degrades performance but is more accurate in some cases. This setting overrides the 'GPU texture scaling' option.
Disable Vulkan memory allocator Off Disables the custom Vulkan memory allocator and reverts to direct calls to VkAllocateMemory/VkFreeMemory.
Disable FIFO reordering Off Disables RSX FIFO optimizations completely. Draws are processed as they are received by the DMA puller.
Strict texture flushing Off Forces texture flushing even in situations where it is not necessary/correct.
Known to cause visual artifacts, but useful for debugging certain texture cache issues.
Use GPU texture scaling Off Force all texture transfer, scaling and conversion operations on the GPU.
May cause texture corruption in some cases.
PPU debug Off Creates PPU logs.
Only useful for developers.
Never use this.
SPU debug Off Creates SPU logs.
Only useful for developers.
Never use this.
MFC debug Off Creates MFC logs.
Only useful for developers.
Never use this.
Set DAZ and FTZ Off Sets special MXCSR flags to debug errors in SSE operations.
Only used in PPU thread when it's not precise.
Only useful to developers.
Never use this.
Accurate GETLLAR Off Accurately processes SPU MFC_GETLLAR operation.
Accurate SPU DMA Off Accurately processes SPU DMA operations.
Accurate cache line stories Off Accurately processes PPU DCBZ instruction.
In addition, when combined with Accurate SPU DMA, SPU PUT cache line accesses will be processed atomically.
Hook static functions Off Allows to hook some functions like 'memcpy' replacing them with high-level implementations.
May do nothing or break things. Experimental.
Enable performance report Off Measure certain events and print a chart after the emulator is stopped. Don't enable if not asked to.
Accurate PPU 128 reservations Disabled When enabled, PPU atomic operations will operate on entire cache line data, as opposed to a single 64bit block of memory when disabled.
Numerical values control whether or not to enable the accurate version based on the atomic operation's length.
PPU thread count 2 Affects maximum amount of PPU threads running concurrently, the value of 1 has very low compatibility with games.
2 is the default, if unsure do not modify this setting.
