Agreed with poster above. My i5-8400 and RTX 2080 could run 2020 at reasonably high settings with about 45 fps (Cessna 172), while the new sim struggles maintaining the same graphics settings. I only get around 20 fps with high stutters. Medium settings seem to work fine though, about 40 fps on my system. Right now this feels like a poor deal, week performance and even weaker visuals than 2020.
Further optimisations will probably take place in the future, but any improvement is probably going to be counteracted by more advanced addons utilising all available resources. Time to upgrade, I guess...
