Gran Turismo 6 (Japanese: グランツーリスモ 6, commonly abbreviated as GT6) is the sixth major release and twelfth game overall in the Gran Turismo video game series. It was popular with critics, won awards, and topped charts in countries around the world. New features included the addition of more cars and tracks, improvements to the car customisation options, and partnerships with the Goodwood Festival of Speed, the Ayrton Senna Institute, the FIA and NASCAR. Gran Turismo 6 is the first-ever video game to have officially certified FIA content.

On October 24, 2013, game developers announced a long-term partnership with the Ayrton Senna Institute, where a percentage of profits from the sale of the game went to the organization, which promoted and provided education to the impoverished communities in Brazil. A free update in May 2014 added a new feature called "Ayrton Senna Tribute", which followed the motor racing career of Ayrton Senna. The update also includes the iconic Lotus 97T, which Senna drove during the 1985 Formula One season.

Debug configuration

This tab is hidden by default. For instructions on how to enable the Debug tab in the settings window, click here.

Setting	Option	Notes
Disable ZCull occlusion queries	On	Very minor performance increase. Prevents car reward screens from dropping to near zero FPS.
Force CPU blit emulation	On	Improves performance and fixes screen flickering.

Known Issues

Working buffer not big enough crashes

• Crashes caused by "Thread terminated due to fatal error: [index buffer] Working buffer not big enough..." can be fixed by enabling the "Disable FIFO Reordering" debug setting. (See this page on how to show debug settings)

Graphical issues

• Issue 12567: A number of graphical issues are known including screen flickering, incorrectly rendered reflections and broken anti-aliasing.

Special Notes

Version 1.00 has a game-breaking crash when finishing races, that was fixed with the 1.02 update. Do not, however, update the game version beyond version 1.05, as newer versions suffer from severe graphical issues, poor framerate and frequent crashes. If you still want to update the game with a version higher than 1.05, you must enable Write Colour Buffers and Read Colour Buffers. Even with these settings, expect issues like screen tearing and broken car reflections. If GT6 won't boot past the Sony Computer Entertainment logo, deleting GT6's save data should fix the problem.
