I tried using Geforce Experience and I regretted it, and went straight back to ignoring it. It was trying to optimise my FS2020 as Low settings, so I changed it to Ultra (since I have a 3080 as well), and it went to 1 frame per second. When I put it back to default and used the Ultra settings in the simulator, I went back up to 30-40 FPS.
I use Geforce Experience to update drivers, but not for optimizing game settings.
