Recently, I have had issues with lag. I'm pretty I have a pretty good system to cope with most games fairly well, which was the case for a while. Now I have to have the lowest settings and still barely get any FPS.
Specs:
Graphics Card: AMD Radeon HD 7700 Series
Processor: Intel(R) Core(TM) i5-2500k CPU @ 3.30 GHz 3.30 GHz
RAM: 16 GB
I am running Windows 7
