When I start the game and go into editor/scenario/whatever, for about 20 minutes everything is fine. Then out of nowhere the FPS drops to the high 10s and low 20s, but only when I look in a certain direction (out of 360 degrees it seems like half of it causes the framerate drop). This happens on all maps. Going back to main menu and reloading the editor/scenario doesn't seem to fix the issue, but it does change the direction I need to look to lag the game, it seems to be random each time.

So far the only fix I've found is restarting the game entirely but that's WAY too annoying. I saw an old post on Bohemia forums about a similar issue and it mentioned changing the memory allocator, but I had no luck with that and changing the graphics settings in game didn't have any effect. I know it's not my GPU/CPU thermal throttling. I also don't remember this being an issue on Windows, but it can't be Linux either because I remember playing this on Linux back in October and this wasn't a problem. My system itself is up to date, but my drivers aren't (I tried updating my GPU drivers and it seemed to fix this particular issue, but introduced several other problems that weren't there before). Is there another way to fix this that doesn't involve updating my nvidia drivers?
