What is this?
RyGT ports the PS4 game Gran Turismo Sport (CUSA03220, update 1.69) to run natively on Windows. It is not an emulator: a converter turns the game's PS4 executable into a Windows GTSport.exe, the original game code runs directly on the CPU, and RyGT's libraries replace the PS4 system while shadGT's Vulkan renderer handles graphics.

Pick your game, update, firmware module and font folders, press Set up, then Play.

The release itself contains no game files.

The first 30 seconds of a race can stutter while shader pipelines compile, and a few draws in the race results screen are skipped due to occasional garbage vertex data.

The loader also supports AMD FSR 3.1/FSR 1 upscaling and an optional NVIDIA DLSS plugin built separately.

Graphics are produced by shadGT's Vulkan renderer, a branch of the shadPS4 project's renderer.

No, online features are explicitly listed as not supported.Do I need to worry about the legality of this project?RyGT ships no copyrighted game, firmware, keys or proprietary libraries - you must provide your own legally obtained GT Sport dump and PS4 firmware files. The project frames itself as interoperability, research and preservation work.
