Demon's Souls is the first installment in the Souls series of games created by game director Hidetaka Miyazaki, and was produced under supervision by Sony's Japan Studio. Set in a dark fantasy world, players take control of a hero who has journeyed to the fictional kingdom of Boletaria, which is being ravaged by a cursed fog that brings forth demons who feast on the souls of mortals. The gameplay involves a character-creation system and emphasizes gathering loot through combat with enemies in a non-linear series of varied locations, with a heavy emphasis on challenging combat. It has a unique online multiplayer system integrated into the single-player where players can leave useful messages and warnings for other players' single-player game worlds, as well as joining other players in their world to assist and/or kill them.

Configuration

Options that deviate from RPCS3's default settings and provide the best experience with this title are listed below.

GPU configuration

Setting Option Notes
Resolution scale threshold 640 x 640 Properly scales the depth of field effect at resolution scales higher than the default 1280x720.
Write color buffers On Fixes missing graphics ingame.

Advanced configuration

Setting Option Notes
Maximum SPURS threads 3 Helps with performance. Don’t mess with this if you have a CPU with more than 6 cores and 12 threads as you may experience performance loss.

Known Issues

Missing Geometry

Issue 4302 - There are certain situations when the game doesn't send geometry to be rendered (like the invisible soldier shield). Can be fixed with this mod Be sure to read the readme file included with the mod carefully when applying this mod.

Special Notes

Gray Outline Removal When Upscaling

When upscaling in this game, gray outlines appear in the hud while in-game and in certain UI elements. You can use this mod to eliminate that. Be sure to read the installation instruction in the description tab of the linked page carefully when applying this mod.

Disable Depth of Field

If you don't want to adjust resolution threshold for proper DoF scaling when upscaling (as mentioned in the configuration section above), then alternatively you can use this mod to disable this effect entirely. Be sure to read the installation instruction in the description tab of the linked page carefully when applying this mod.

Incorrect FPS counter

Demon's Souls has an internal technique where it will output duplicate frames if the games performance is not at the FPS cap. This makes the FPS counters report that the game is running at 30FPS (or 60FPS) at all times while the actual performance could be 15FPS as the game is outputting duplicate frames if your performance is too low. This is not a bug, its just an unfortunate result of how Demon's Souls works. The reliable way to check true performance is to record gameplay footage and then use tools to analyze the frame-rate from the footage. However, users may use the FPS patch, which disables the game's internal frame duplication logic, to check performance levels.
