Today I went to play some rust, and I was getting some crappy fps. after investigating I found that my GPU clock didn't go past 450MHz. My GPU is a EVGA GTX 770 2gb with acx cooler. Another weird thing was that my CPU loads were reaching up between the high 50s and mid 60s most of of the time and sometimes dropping down to low-mid 40s. This might be an outcome of the low clock speeds. I haven't overclocked my GPu or anything and just left it to it's factory overclocked speed. This wasn't happening before, as i used to get great fps, now it stays at around 20-35 fps if i'm lucky. Help would be appreciated .
