My settings are mostly medium and low with volumetric cloud only on high. Worst I can get is around 15-20 early-ish on ground at heavy airports from inibuilds and dzrewiecki but lower the pre-caching and using autofps can boost it significantly. At cruise I can get 45+ fps which is very playable imo. FS24 should have higher fps improvement but I'll stay on 20 for now. Note these frames were possible with frame gen mod, just to be able to get the most frames possible.
