|Agree that GTA 4 is a very poorly optimized game. |
I can only hit 33fps @ 1920x1200/medium with my rig. Same story: frame rate takes a dive when I increase the view distance. It's definitely CPU-limited, as lowering the resolution does not help.
To max our GTA 4, you need a quad-core CPU. A Ph II X4 with a 5770 would make a better carjacker than an X2 with a 5970.
