Brief description of the issue: MSFS start initially normally with normal FPS, but then after 2 minutes after loading a flight, locks solidly to 10 FPS, no matter what graphic setting low or ultra, with and without addons in the community folder. This is ridiculous, no matter what I try the problem persists.

Provide Screenshot(s)/video(s) of the issue encountered:





Detail steps to reproduce the issue encountered: Load up FS2020 Problem-free initially, load up at any default airport , in any aircraft, Initially 25-40FPS Id say maybe more, and then instantly drops to 10 FPS and locks up a solid 10 FPS , No setting or anything helps. Doesn’t matter on the ground in the air, it’s the same. It’s Unplayable.
