If you turn on DSR, but don’t set your screen resolution in FS2020 to greater than your monitors native res, then you can turn DSR off since you’re not using it.
Experiment and tell us your findings! I’m all about tweaking this game to get max performance out of it.
The new TAA algorithm released a few months ago works well when turning down below 100%, MUCH better than it did at launch.
Having the render scale at 200% and native res, has yielded a poorer framerate and inferior visuals vs running VSR/DSR at 4x and render scaling at 70-100% in my experience. I run at 60% render scale and I’m pretty happy with it. It gets a little muddy when doing super fast camera movements, but it’s not anywhere near as bad as if I ran at my native 1080 and 100% render scale.
Again, the new TAA system is not as bad as it was at launch. At launch 1080p @ 100% straight up looked bad and lo-res for whatever reason. Kind of like Red Dead Redemption 2, it’s one of those games that straight up requires supersampling for it to look good IMO. It was mostly noticeable in lights and trees looking like blobs and lacking definition.
