I got a GTX 1050 Ti with a Phenom X6 1090T. My GPU always maxed out on 99% and sometimes 100%, with not much bottleneck on the CPU, but 2 days ago I was playing PUBG and streaming w/ my friend and It was fine and then I stop the stream, do some stuff, then shut the PC down. But about 9 hours later, I turn on my PC, do some stuff, then open up PUBG. My FPS is low. Where it usually around 60, it's 30 and lower. Later I found out that my GPU isn't maxing out and it barely go above 50%, but the CPU isn't going above 70% and the thermals are well below 60 degrees Celcius, and it never goes up to 80 degrees. It does the same thing with CS: GO and Minecraft, but it maxing out on Unigine Heaven and Superposition. Please help me. I still have the warranty but I don't even know if that will help. I tried clean install and reinstalling the graphics driver and system restore, but none helps.
