Not sure what is causing the problem but when I don't click on anything the cursor seems very laggy and makes FPS drop from 144 to 20-30. it happens in game as well. When I hold left or right mouse button and make the cursor solid and do the same action the FPS doesn't drop at all. Going to reinstall game to see if it fixes.
