Hello,

       I am using Acer Nitro 5 AN515-51, NH.Q2QEY.004. I always gaming with AC cable plugged in. But i am suffering fps drop spikes in every game after 10 minutes. It happens every minute, in length of 2-3 seconds and sometimes longer. It affects the overall quality of gaming. It is like this since i buy this laptop 1,5 years ago and never found a solution. The CPU and GPU temperatures were high like 85-95 celsius. Then i undervolted my CPU -135 mV and used maximum fan speed with predatorsense(a version of it is working well for nitros) when gaming and it solved my temperature problem like 15-25 celsius decreased. But the fps problem still persists. I don't know what is causing this issue.

      Before writing this, i played a game for 30 min and suffered fps drops a lot and I checked the temperatures after this issue caused the game unplayable and the results were interesting. Because my CPU and GPU temperatures were never above 75-80 celsius. I checked the intel xtu temperature graphics and it is showing that i am sometimes suffering thermal throttling during 2-3 second. It is matching with my problem. But the temperatures were should be low enough to not cause this. Also my all drivers are up to date. What may be causing this?
