System is Phenom 9600 X4 @ 2.3GHz 8GB RAM and GTX 650 Ti.
During Battlefield 3, My GPU will only ever have 65% load max. My CPU stays around 75-85%. My Frame Rate hovers around 15-25. Why is my CPU not maxing out to get me a few extra frames?
BF3 is a very CPU intensive game and your CPU is fairly weak compared to your GPU. It's causing a bottleneck. Upgrading your CPU will give you much better results.
