I was playing the Beta 1, and had around 40-50 fps with stuttering. Sure my PC is trash ( i5-3330 3GHz, AMD HD 7790 2GB, 8GB RAM ) and they said they improved with Beta 2. When I get into a game, and do anything, like moving, looking around or something happens near me, my fps drops to 2-4. I just applied the newest Optional update for the AMD driver: 18.8.2 but nothing is wrong with other games I play. Someone suggested me that this is happening bc of the tessellation and my old GPU can't handle it. My game is on All Low, only the resolution is at 1920x1080 and Fullscreen. I don't know if this is happening to anybody with low end PCs but I'll have to refund if this keeps up. I'll have a new PC sure, when I'll get money, but until then 23€ is 23€ wasted that I cannot use.
