I’m one of the lucky ones who enjoyed the first year of MSFS with no significant performance issues and no CTDs. After Sim Update 5, I couldn’t launch the simulator and (to cut a long story short) ended up having to do a reinstall from the Store. Everything is now working fine, with excellent performance once I’m in the air, BUT I’m getting huge FPS drops (down as far as 6 FPS at times) and dreadful lagging on take-off runs and landing (i.e. when I’m actually on the tarmac). Exactly the same problem occurs with planes as different as the default Cessna 152 and the FlyByWire A320NX.
Windows 10 is up to date, as is Flight Simulator (version 126.96.36.199). My GPU is an RTX
2080ti and the NVidia driver is also up to date. I have lowered my graphics settings to Medium, but with no result. I’ve deleted my previous Rolling Cache and my Community Folder is empty. Can anybody help?
