From 1080Ti to 3080, what settings to tweak for a WOW effect (Oculus Rift S)?

[Elaphe]

The prices of the GPUs are starting to drop. Now here I can find a 3080 for less than 900€. I might wait a couple of months, just before the new series are released. I am using Assetto Corsa with my Oculus Rift S. With my current setup (i7 10700K, 32 gb, SSD, 1080Ti...) I have the game configured to be on the limit to keep stable 80 fps, with most of the graphic settings set to high or very high. When I purchased my new card the first thing I will do is to increase the supersampling (now at 1.0), for a crisper image. What settings in the AC's video configuration or in CPS's configuration do you think I should enable or increase and have an instant and noticeable improvement in my graphics and still maintain the constant 80 fps?
