I have an R9 270x paired with an FX6300. and in games i get occasional lag, not bad but like 30-35fps in medium settings in games like saints row IV, i checked to see if i just couldnt run it by looking at my usage, but my GPU is about 50-60% and my cpu is about 70-75%, they never fully utilize for some reason and i get lag. Any way to fix this? Even on low settings on some games, i get tiny lag spikes for no reason.
