I’ve never been able to get anything sharp with DLSS.
That’s why I disable DLSS for VR and put TAA
I stay in DX11 and go through VDXR. If you are on MSFS by MS Store then choose VDXR in VirtualDesktop.
In VD, I am in ULTRA at 150 Mb/s and 80% sharpening at 90hz
Overall I have good image quality and a constant framerate after which there remain very subjective interpretations regarding the feeling of things.
What is valid for one will not necessarily be valid for another.
