EDIT: Found why there was a problem. Click - That was my problem . It's because gta4 only supported GPUS up to 2gb, so since mine is 3gb, it miscalculated how much ram was up for use and thinksi don't have enough
@jason387 - Yes,it's GTA 4. I've used ENB series by Vucko 4.0(I think) ,cars,city textures,road textures by Fonia5


Looks like I was right after all, the problem was with VRAM.

Not exactly what I described, but the symptoms all pointed towards "not enough" VRAM and not something else.

Did you actually solve it?

It runs much smoother on nvidia cards. Because it is very poorly coded!

No,i didn't .I removed the game from the PC,i can't stand gaming under 60fps .I was having 10-15fps lower performance with a card 2.5x slower than my current one.I'll play something else,might try saints row 4.
