Every game the same error "CreateDXGIFactory2" unable to find "C:\WINDOWS\SYSTEM32\d3d11.dll" Any solution?

Yes, stop using sweetFX 1.5.1 or lower for DX11 games on win8.1 and win10 and use SweetFX 2.0 which uses ReShade as it's injector.

That helped me, thank you. Now it work's fine

No problem, glad you can enjoy SweetFX again. :)

i have the same error with battlefield 3 and sweetfx 1.4 + tvlevels. wanna use this preset but with reshade/sweetfx 2.0 i get an red error message after starting :/

Screenshot please?

@Zom Screenshot does not capture that error message.

It's entirely possible to capture any and all error messages from reshade using printscreen IIRC.
