I got this problem too,even campaign drops to single digit FPS.

I got this problem too,even campaign drops to single digit FPS. music and sound is also gone except for cutscenes...I have tried reinstalling but no dice

I have the same problem but on exo zombies. The sound would cut off and then the game frame rate would drop dramatically to 2 frames per second.

When I play online I noticed that the frames dropped for the first 5 minutes I guess its loading still idk I'm thinking about downloading my game toy 2tb external harddrive maybe it will load faster.. Its pretty noticable when I play up close on my 46 in

I am having this problem too. Can you even play single player campaign? Did you get a resolve to this?

All, I have the same issue. Game runs fine until I'm in the cockpit, then the FPS tanks to single digits. I can barely click through menus. I'm on a brand new $4k computer: intel 10700k, evga 3080 FTW3 Ultra, 16gb ram OC to 3800mhz, game is on an m.2 ssd
drive. My computer that I upgrade from runs this at 2-3x the FPS than my new machine. There is definitely something wrong with the game/driver situation. I did some testing and the FPS drop to single digits goes up to 60fps if you alt+tab out and have a different
window over, even if it's off the screen. It appears that the FPS issue only happens when the game is in focus and fullscreen.
