When I loaded up Arma today, my screen was really shaky, like actually shaking. When I got to the main menu, I was only getting about 3-5 fps, and nothing would fix it. I had no other programs open, I tried uninstalling and reinstalling drivers, going back to the previous driver, switched to 32 bit, back to 64, deleted and reinstalled Arma, Restarted my computer in safe mode, nothing works. All my RAM is working properly, I have a good amount of CPU usage, Graphics card is working fine. I have an i5 4690k, a GTX 960, and 8gb ram, I can almost always run the game in the 40-60 fps range even with heavy mods. I was at the main menu with no mods loaded. This was very all of a sudden and I don't know what to do. If anyone has any clue what's going on I would really appreciate it... my head hurts...
