I have a phenom ii x4 965 overclocked to 3.8ghz paired with a r9 270 also overclocked and 8gb of kingston hyper x fury ram ddr3. When i am playing bf3 i get randomly fps drops to 40 when it should be around 60+. Most would say the processor is bottlenecking so i opened up ram, gpu, and cpu usage and while cpu usage occasionally spikes to 90% usage it mostly stays in the 80's but the gpu usage fluctuates anywhere from 80-99% usage and bf3 only uses 3.5gb of my 8gbs of ram. So my question is why am i getting these random fps drops to the 40's when none of m hardware has reached 100% usage?
