Can you set an FPS cap?
So,not to brag but I have a good PC. and that's oddly bad. if I am in lane with no enemy's around I get 400FPS but if something happens like a teamfight I drop to 200-300 FPS which ends up making my game look like its stuttering for a bit and can mess up how I play a bit. it only lasts for like 5 seconds but its a little annoying...
