Question: the DefaultGraphicsRHI=DefaultGraphicsRHI_DX11 line. Does this drop it to DX11? I left that line out and it seems to work with DX12 no issue? Thanks
Yes, that line will force the game to run in DX11 mode. I would recommend leaving it out, the effects commands will work fine. They're just generic UE4 commands, you can see a list of a lot of them here: https://www.pcgamingwiki.com/wiki/Engine:Unreal_Engine_4
I would also recommend changing the vignette command from r.Tonemapper.Quality=0 to r.Tonemapper.Quality=1, because 0 disables both vignette and the tonemapper, 1 only disables vignette and keeps the tonemapper, and 2 would be both enabled.
