OCing the CPU or GPU? And no before that it was an hd 7770 and that was the machines first card

that's definitely a CPU bottleneck, back in the days when i upgraded my Phenom II 1055T to a 2600K, i got like a 20FPS increase.

start with the cpu and if nothing gets better then try the gpu but its probably the cpu. dont be concerned with the vram for now if its only using 800mb then thats all it needs i dont think u have a problem there. and the other thing is probably just the benching software it is it a free version or paid? and maybe try uninstalling & reinstalling or updating it if possible

Should I overclock the CPU or GPU? And I've never had any nvidia cards in the machine

It's GTA IV's native benchmarking utility

@smex I've tried the nomemrestrict commandline.txt file and it makes no difference

Your best bet is to upgrade your CPU. although overclocking can help a little, it wont be very significant (1-5fps increase) unless you can hit something crazy like 7GHZ

A CPU upgrade isn't in my reach at the moment so I guess I'll just stick to games like crysis 2 which I can run on ultra + DX11 at 30fps then smile.gif
