I’ve had my 1660 for a little over a year now and it’s never peaked performance. It fortnite etc I can get 200fps stable but nothing above or lower for some reason. In any game I play besides VR I have low gpu usage. In beatsaber I used to be able to run decent settings and now anything above low with no detail in reflections or anything I drop frames. My ryzen 5 3600 is over clocked to 4.3 ghz and has a wraith max cooling it. Both the CPU and gpu have new paste and the thermal pads haven’t been touched. My ram is Corsair vengeance rgb pro 3200mhz 16gb and I have a x570 asus board. The cpu maxes out around 80c I believe and gpu never has gone above 70c. The CPU always sits at 3.9 ghz and never boosts. It sits at 50c idle and I have 2x140mm front fans and 2 exhaust so I should have enough airflow as well. If I lower my settings in fortnite my gpu drops frames and if I put my FPS around 144 on high settings I drop frames but my hardware is barely being used.
