FSR can be tested with a VR mod and it`s ok, but DLSS is far superior. Since both are free then why not have both?
beside, NVidia users are almost 80% of the market according to steam.
the point for me is unless you're willing to compromise in graphics (including in my case reduce PD to 60%), on VR is hard even get to solid 45. DCS is getting beautiful and is a shame to miss all of that in VR no matter what GPU you own.
Of course if you compared to native res. But if you compared to the render resolution then there are only benefits.
The point for me is FSR 4k looks a lot better than native 1440p with almost the same performance
In fact, at least compared to MFS, DCS for me runs a lot better and with better graphics. In MFS i need to put the graphics on potato mode to get decent FPS.
BTW i have a 2080ti also
