Although the DX12 option only exists in 2D (PC) graphics settings, enabling it (including MSFS restart) does have a tremendous effect on VR performance, too. Please see DX11 vs. DX12 VR results below, these are two ‘identical’ benchmarking runs each. So I suggest going with DX11 until we see substantial DX12 fixes. As far as DX11 is concerned, I did not see any obvious visual differences to SU6 yet.
