Sounds gpu bound. What card and resolution?
Don't Bump it P.O.s the Mods. GTA 4 is a very demanding and optimized game it will eat up a buch of GPU power and CPU so your GPUs running at there max is a good thing.Not sure what just happened so bump?

The recommended hardware is always much lower than in reality so it seems. Also I agree GTA 4 is a poor console port in typical Rockstar games fashion but good thing the curse was broken with MP3.actually that is wrong its just GTA IV is very badly coded so it pushes gpus harder ? recommended GPU for GTA 4 is a HD 3870 ?
SLI 470's, 1920x1080. My specs are in my sig. Im also using IceNhancer V2.1.
your problem is iCEnhancer remove it and see your FPS go over 100fps+
You can test for CPU bottlenecking by lowering your resolution. If the FPS doesn't increase in the particular situation you're testing, you're CPU bound. Otherwise you're GPU bound.
GTA IV is traditionally a very CPU hungry game, but it's not so demanding that an i5 @ 3.7Ghz can't provide a good experience.
The problem when the game launched wasn't that you needed a crazy awesome CPU, because you didn't it's just that when you didn't quite have enough CPU power there was nothing you could do about it, you can't turn down the CPU requirements for a game like you can the graphics requirements, if you're GPU limited you can trim down the resolution, the AA and AF, the draw distance, the shadows and lighting and a million other things to improve FPS, with CPU you're more or less shit out of luck, maybe the amount of peds/traffic mattered a little.
You can always confirm where the bottleneck is by simply altering video settings, if you lower or raise the load on the GPU and the frame rate changes you're GPU bottlenecked. Theoretically if you're CPU bottlenecked lowering the graphics wont give you a significant increase in frame rate.
um nearly every setting in GTA 4 is relying on cpu power. in fact the cpu plays a huge role for many settings in most modern games.GTA IV is traditionally a very CPU hungry game, but it's not so demanding that an i5 @ 3.7Ghz can't provide a good experience.

Overclocked both cards to 700 core and my FPS stayed much higher, though my minimum was the same. My CPU usage also doubled, before most of my cores stayed at or below 25% usage and now they are at least 50%, kinda weird. My GPU's are averaging 97% usage but its fine now that my CPU usage is higher and my average FPS is much better.
I find it all this hipster talk about how a ultra fast CPU makes games run faster/better hardly believable being I have had no problem running games at 60fps on my golden moldy OCed Phenom II x4 CPU. I guess if you are after 120Hz game play then an i5 or i7 is the only option in some cases. As for GTA4 on my Phenom II x4 955 @ 3.6Ghz and 560SE @ 1680x1050 I am seeing 45 to 50fps with some ass dips down into the low 30s intermittently on occasion.um nearly every setting in GTA 4 is relying on cpu power. in fact the cpu plays a huge role for many settings in most modern games.
for GTA 4 if you run full max settings, it is 100% cpu limited in many spots even with my 2500k at 4.4. shadows and draw distance alone kill the framerate and those seem to be mostly cpu related NOT gpu related as lowering the resolution does almost nothing but lowering those settings will bring the framerates right up. so the fact is even my 2500k at 4.4 cannot provide a nice experience in this game on max settings especially if trying to use vsync.
A GPU is not about conserving electricity it is about playing games LOL.

I agree +1^ and well said I could not have said it better.Stuff like shadows should have almost zero impact on the CPU, these are things calculated by the GPU, anything graphics related is. The CPU tends to control physics and animation and in GTA IV the blending of the 2 using the euphoria engine, and AI routines. The amount of cars and peds tend to effect that the most and so to some degree the draw distance as that decides how many are being calculated.
The rest such as resolution, texture quality, shadow quality, post processing effects, AA and AF are entirely GPU calculated, there is some nominal CPU overhead for driver functions but basically 99% of the work for these things is GPU bound.
Whether or not you're GPU or CPU limited depends on a few things, you can take even the most GPU hungry game and if you dial down the graphics settings sufficiently so your running at higher frame rates (thousands of FPS) you can switch the bottleneck to the CPU, so it can change depending on your expected/target FPS, I don't know what sort of frame rate you're after, but either way a 2500k @ 4.4Ghz is way more than enough for a reasonable frame rate at 1080p
EVERY setting that keeps me from staying at 60 fps in GTA 4 on max settings with a gtx670 is cpu related NOT gpu related. I have probably spent more time testing this game then most people have playing it. shadows and view distance are a big problem for the cpu NOT just the the gpu and that is a fact. I already told you that I can lower the res in those cpu dependent spots and my framerates remain the same yet I can lower shadows and they go way up. that alone would tell that it is a cpu intensive setting.Stuff like shadows should have almost zero impact on the CPU, these are things calculated by the GPU, anything graphics related is.
