Hi everyone. I have a 3gb VRAM Sapphire HD 7950 standard edition (not vapor-x) paired with 8 gb of ram, and an AMD 6300 processor. On GTA IV at max settings, I am getting slightly choppy video while only using 1211/3048 mb of VRAM. I tried setting the priority for GTA IV to high in Task Manager (Window's 7 Pro). Is there a reason that I am getting choppy video? Is my processor bottlenecking the setup? Thanks in advance
