Gran Turismo 7 on Unreal Engine 5: fan build twice as fast as the PS5 emulator
The creator of the YouTube channel SvenX. is single-handedly rebuilding Gran Turismo 7 on Unreal Engine 5 — unofficially and without Sony's involvement. In a recent video, his version runs above 80 frames per second, while the original through the PS5 emulator delivers around 33. The author has not yet promised a public build.
What is this project
YouTube channel SvenX. is running an experiment that has nothing to do with Sony or Polyphony Digital: the console exclusive Gran Turismo 7 is being rebuilt from scratch on Unreal Engine 5. This is a personal initiative by one enthusiast, not an announcement of an official PC version. On November 3, the author posted a video in which the original and his own build are compared side by side.
How much is done
So far the amount of content is modest: two cars and two tracks have been moved into the new environment. One of them is used as the basis for the frame comparison with the KytyPS5 emulator. The author's goal is to bring the graphics, interface and sound up to the level of the console version, and then recreate the menu, matching the original both in look and in function.
The numbers: emulator vs UE5
- Test bench: AMD Ryzen 9 5950X, GeForce RTX 4080 — identical hardware for both variants.
- KytyPS5: the PlayStation 5 emulator produces around 33 frames per second and suffers from graphical glitches — objects pop in suddenly.
- Unreal Engine 5: over 80 frames per second.
- Technologies: the build uses DLSS and frame generation (Multi Frame Generation) on RTX 4000 series graphics cards.
The difference in the picture is not radical, though: in reflections the original is still more accurate, and the late loading of objects is more likely a problem of the emulator itself. The point of the endeavor is not optimization — on PS5 the game has been running properly since 2022. The interest lies elsewhere: seeing a familiar simulator on a completely foreign engine.
A hazy fate
The demo has not been announced, and whether the build will be released publicly is unknown: an unofficial project using Sony's assets carries an obvious legal risk. In the comments to the news on PlayGround.ru, players doubt both the physics — in such a port it will no longer be "native" — and that Polyphony will turn a blind eye to such unauthorized tinkering.
