LAG

Every time I update my game, the lag gets worse and worse. I cant even play on gridmap without the game freezing or getting the Blue Screen of Death (im serious). I can play other games like War Thunder at almost max graphics and I cant stand that this game wont get over 7 FPS. I really enjoyed this game until the last 3 updates came out. I really want to be able to play this game but I cant.

I have updated all of my drivers and it hasn't done anything.
