CPU Bottleneck?


Mar 23, 2012
Hey guys i was messing around with Dirt 3, running benchmarks and such, when I noticed something wierd. I normally game with Ultra settings and in Full HD resolution(1,920x1080) then I get around 33 FPS; however even when I turn everything right down(even the resolution to 640x480) I only get to around 68 FPS. Could this be a sign that my CPU is bottlenecking my graphics card? I thought about it because I know Dirt 3 tends to be CPU intensive.
My current system specs are Intel Core 2 Duo (2 cores at 2.4 Ghz), 2GB RAM and ATI Radeon HD 4770.
