warn: D3D11InternalCreateDevice: Adapter is not a DXVK adapter
Means it is not using dxvk's dxgi.dll but instead the system one. If you have remembered to extract it along with d3d11.dll then there is nothing we can do
Also, on a side note, you might want to check that bInitializeShadersOnDemand=False is set in the game's ini files for its D3D9 renderer. With that in place UE3 should be pretty stutter free. Some games don't ship that configuration by default for some reason, but most do.
Like @ghost says, some games insist on loading dxgi.dll from C:\Windows\System32. If thats the case, they get the regular Windows one which is incompatible with DXVK. There's nothing we can do about that.
Do make sure you actually copied the DXVK dxgi.dll too.
DXVK 2.1 is not crashing and seems to work better, it reduced checkpoint freezes and random stuttering. DXVK 2.1 with dx11 works better than 2.7 in DX9
For some reason now latest version works, but still pointless. All versions newer than 2.1 is a stuttery mess in this game
DXVK works with DX9, but the game still suffers from stuttering.
Native DX9 works way worse than DX11, perhaps that's why DXVK can't completely fix stuttering.
