As soon as OBS is open, even without recording or streaming, my FPS in League of Legends drop from the capped 144 (or 120 if i cap it at that) to almost exactly 108 and I don't know why. FPS is capped, and my PC is more than powerful enough. vsync doesn't help. I also disabled the GeForce in-game overlay. The issue is always there in Borderless mode, but not in windowed. If i enable full-screen, at first my fps are at 144, but if I tab out and back in once, the fps drop to 108 or so. Does anybody have ideas on what to do
