OC Settings aren't being applied after some time in Overclocking and Cooling Posted Thursday at 07:28 PM What is your fps without overclocking after hours of gaming? It doesnt make sense why the frame rate would drop to a 3rd of what is it. It seems like a program / driver issue to me with a memory leak. The only other thing I can think of is the GPU is overheating and downclock to keep from damaging itself. But hours into into gaming?? Your cpu might be the one overheating and downclocking. Just some thoughts.
