Gran Turismo Sport, the PlayStation 4 racing game released in 2017, is now playable on PC through an unofficial community project. Sony has never released the Gran Turismo series on PC, but developers are finding ways to bring its racing games to the platform without waiting for an official port. The project, called RyGT, is available on GitHub and includes performance improvements and support for AMD FSR 3.1 frame generation. However, it still has visual glitches and requires some technical work to get running.
The developers have used a recompilation approach to make the game run on PC instead of relying on a conventional PlayStation 4 emulator to reproduce the entire console environment. This approach translates the game’s executable into code that can run on a PC processor, while supporting components handle system functions and graphics operations. The graphics layer uses Vulkan to render the game on compatible PC hardware. This method can reduce some of the overhead associated with emulation, although getting a console game to run properly still requires considerable work.
RyGT also includes options to address shader compilation stuttering, a common problem when running games through compatibility layers or emulators. Players can precompile previously used shaders, pause the game when a new shader needs to be compiled, or compile shaders in batches during pauses. These options aim to make gameplay smoother, although they cannot eliminate every performance issue.
The developer reports frame rates ranging from 42 to 60 FPS, depending on the number of cars on screen. Testing has been carried out on systems with an Intel Core i7-13700KF and RTX 4070 Ti, as well as an AMD Ryzen 5 9600X and RTX 3060. However, the reported figures should not be treated as guaranteed performance for every system, especially while the project is still being developed.
Support for AMD FSR 3.1 frame generation is another notable addition. The technology generates additional frames to make gameplay appear smoother, but its implementation in Gran Turismo Sport has limitations. The game does not provide all the motion data needed for proper frame generation, which can cause ghosting around fast-moving objects and interface elements. The developers are also working on a multithreaded renderer that could improve performance in future versions.
Players should keep in mind that this is not a conventional PC release. RyGT does not include the game’s files, so users need to provide their own compatible game dump and system files from a PS4. Setting it up is more complicated than installing a regular PC game, and compatibility and performance may vary depending on the hardware and software configuration. Online play is also unavailable because Polyphony Digital shut down Gran Turismo Sport’s online servers in January 2024.
Sony’s response remains uncertain. The company could take action if it believes the project infringes its intellectual property, although RyGT does not bundle the game’s assets. There is no indication that Sony has approved the project or plans to support it. The company has generally treated Gran Turismo as a PlayStation-focused franchise, even as several other PlayStation games have made their way to PC.
An unofficial PC version could help the game reach racing fans who do not own a PlayStation, particularly those with gaming PCs and racing wheels. It also raises the question of whether Sony is missing an opportunity by keeping the series off PC. An official release would offer better optimisation, easier installation, and proper technical support, but Sony may prefer to keep Gran Turismo as a reason to buy its consoles.
