Following SU5, when taking off from grass or dirt strips, my FPS slows down to 10 and stays there. Known issue?
Having the same issue, except it’s dropping to 10 fps every time I click into the game - both cpu and gpu usage drops to about 10% when in-game but when tabbed out or on another monitor it jumps back up to about 80-90, as well as fps going up too.
grass got a lot higher, and it uses transparency, which causes overdraw, which can really impact FPS
Can vote it here:
Grass height now ridiculous since update - Bugs & Issues / Scenery - Microsoft Flight Simulator Forums
This issue was “resolved” by the developer of the plane, who removed the new dust-effect (when landing on dirt/snow/water), until he can figure out what caused the massive FPS drop.
