So I recently bought a GTX 750 ti to pair with my cpu AMD-A8-5500 because they are both low power and dont really need to upgrade anything else. But now I get very low GPU usage for example in GTA V I get about 40% usage on my GPU while CPU is at 100% I know my cpu is a somewhat bottleneck but this is very severe. I also tried tf2 and I get about 15% gpu usage and low cpu usage. My integrated card never had this problem before anyone help me out?
