I was wondering why my rig is stuttering and freezing in game for a second at times. Usually when I play Rainbow Six Siege. I have a i7 8700k with 16gb RAM. 165hz monitor with GSync. I tested temps and they look fine. (70C max for GPU, 65-68C for CPU). I have all updated drivers. Is it possible that it might be Shadowplay from GeForce Experience or is this a hardware issue?
