I just downloaded SwiftShader to see how it runs with Toribash. I tried using it with Toribash but it doesn't work.

To use SwiftShader, you copy/paste two DLL files (D3D8.DLL and D3D9.DLL) into the same directory as the application you are trying to run it with. This would cause the app to run the SwiftShader DLLs instead of the usual D3D.DLL (Direct3D) from System32.
Though, the README also said that some apps run DLL files directly from the System32 directory, and those apps won't work with SwiftShader unless it is somehow modified.

I have tried it with a few apps and it works fine, so it's not a problem of the files.

So does Toribash use Direct3D?
If so, how would one 'modify' it? So that it runs with SwiftShader.
Am I even asking the right questions?

Sorry for being computer engineerically retarted.

Well it only works on Intel x86 or comparable processors so that might be the problem. As for Toribash using Direct3D I would have no idea.

Toribash uses OpenGL, not Direct3D.

Well, that's question solved.

I wonder if there's anything like SwiftShader for OpenGL.
