Are you sure the graphics card is enabled? Have you run any benchmarks?
Check the cable of your monitor and where it is connected (motherboard or gpu) in the back of your PC. You might be using the processors integrated graphics.
1. I'm not sure what you mean by 'enabling' graphics card, so you'll have to educate me on that for it to work
2. I haven't ran benchmarks, but I have tested Just Cause 2 and 3, and they both have received FPS levels lower than 25, and stutter very frequently.
3. My cable is plugged into my graphics card.
