Well, I completely agree with the original poster. Went from minimum 45fps -70 fps with SU1, SU2 lucky to get more than 12fps. And I have tried all the tricks: empty community folder, dropped my graphic settings to low, deleted cache, etc. Even multiple CTDs. There is a memory management component that they are monitoring that may be my major issue but it is unplayable.
I've participated in too many beta tests for MSFS2020 and now 2024. It used to be fun to test but ultimately my main desire is to fly. I return to SU1 with hopes that the final SU2 issues will be resolved.
