Yup, my thoughts, too. I re-installed the sim last night. Pretty much all of the settings were recovered from the cloud. So, that works 
. Have the sim pretty much on the high side while turning down some to low or off - such as the raytraced shadows and motion blur. The texture resolution, though, is at medium at airports such as KFJK and EDDF with broken clouds. At high, VRAM may still be at the edge, but FPS suffers way too much. Anisotrphic filtering gave me 3-4 fps more at 8x, compared to 16x. I also cap my FPS to 60 fps via Nvidia control center. I believe there’s still a some room for performance optimization on the sim side for the future.
That said, I mostly fly the Fenix aircraft and the IniBuilds A330, which, in my opinion, is really good for a default aircraft. GA aircraft will definitely be better on the FPS side.
