Question 1

Is there a Custom Shaders Patch (CSP) for Assetto Corsa EVO?

Accepted Answer

Yes. Prism is the first custom shaders patch and content manager for Assetto Corsa EVO. It replaces 71 of AC EVO's DX12 shader programs with physically-based spectral alternatives at runtime.

Question 2

Is there a Content Manager for Assetto Corsa EVO?

Accepted Answer

Yes. Prism includes a standalone desktop app (built with Tauri) that manages shader configuration, camera settings, tonemap options, and launch config for Assetto Corsa EVO — similar to what Content Manager does for AC1.

Question 3

Does Prism modify game files?

Accepted Answer

Prism adds a single DLL to the AC EVO game directory. No existing game files are modified or patched. Remove the DLL and the game returns to stock.

Question 4

Does Prism work after Assetto Corsa EVO updates?

Accepted Answer

Prism includes an auto-remap system that handles most game updates automatically. When a game update changes shaders fundamentally, Prism disables itself safely and a patch is pushed as fast as possible.

Question 5

Does Prism support HDR output?

Accepted Answer

Yes. Prism can promote AC EVO's swapchain to 10-bit PQ HDR (ST.2084) or 16-bit scRGB. Multiple tonemap operators are available including Gran Turismo tonemap, AgX, ACES, Reinhard, and Hable.
