I have Gtx 1060 3gb, 1x8gb ram 2400, Ryzen 1400 stock 3.20ghz. In gta 5 ( but even in other games ) I get very low performances: i'm talking about 40-50 fps in gta 5 with High settings ( not very high or ultra ). There doesn't seem to be any kind of bottleneck, but gpu usage is always 60% max 70% with a temperature of about 70/75° and cpu the same usage. None of the 8 cores seems to reach 90-100% of usage, there's stability. I don't know what to do.
