Hi,

Firstly I just wanted to say I'm not complaing about how well GTA4 runs on my computer, I've done hours of research and understand how it was a badly ported game and so on.

But I have some questions about my first home built system that have arisen from trying to get GTA4 to work. I've seen plenty of videos on youtube of GTA4 running on way worse systems than mine, however it literally will not run, even with the worst possible settings. I barely get 20fps with the in game benchmark tool, with everything as low as possible.

Here is my system specs:
CiT Black Ops Case & 500w psu
Gigabyte Z77-DS3H
Intel i3 2120 3.3ghz
8gb Corsair Ram
Asus Radeon HD6670 2gb GPU

I understand an i3 is not ideal and may bottleneck the system, and GTA really needs quad core, although surely not to such an extent that it refuses to work? I'm also starting to doubt the Asus graphics card, and whether its drawing far too much wattage from the motherboard (it has no external power)/generally a poor quality card.

What would you say I should change/test first in order to achieve better results?

I have updated all the latest drivers and such, but to avail. Again I'm not asking you guys to fix GTA for me, just asking whether you can see any issues with my system/things you'd change.

Cheers
Harry
 
Well the 6670 isn't a amazing card to begin with its more of a entry level card for gaming. So I can see how that could possibly hold you back. Although as low as possible seems a bit weird. Your card if its not drawing additional pci-express power will more likely then not be causing a power issue. The game is great on the PC but as you said its not a perfect pc port I found the DLC's more fun personally.
 
i think hes trying to figure out whats wrong with his computer giving him the performance it is 20 fps isn't a impressive feat on low settings in gta IV. So one could say well his CPU isn't as powerful as most who game and same goes with the Graphics card.

@bigshootr8 I think I'm going to replace the graphics card, thanks for the advice.

@sunius/bigshootr8, Apologies! I just can't figure out what is causing the terrible performance. It really is the worst possible settings, and I just thought there must be something bigger wrong rather than just how badly GTA was ported.

I also have this weird glitch, after like 10/15mins of trying to play the game it will freeze, the sound will begin to stutter, I can only describe it as a duhduhduhduh but really fast, and then the game will continue to work (but lagging terribly as always). Even after shutting down GTA the sound continues till I restart the computer. Could that be an associated problem with a graphics card?
 
Your CPU should be more then enough it wouldn't be bottle-necked with your Sandy Bridge i3. The only concern I have is your PSU. What is the labeled 12v rail amps/Watts (should be labeled under the 12v). I don't particularly care for cases that come with PSU's normally they aren't great.

haha im guessing that could be the problem then. sorry for sounding completely stupid but could you explain why that would have a drastic effect on the games performance?

could you recommend a good psu upgrade thats not too pricey?

turning the settings up (in game) just kills it completely.

My PC is very similar to yours actually, i3 2100 with a 2GB DDR3 6670 and 10GB of ram..
I play GTA IV and I get about ~35 avg fps on med-low settings, with a min of 20 fps.. Do your fps hover over 20 or below?
 
No problem well it wouldn't have an effect really on performance well I take that back it may. Basically what the 12v powers is the PCI express lanes among other things. So moving up in graphic cards will be very difficult considering how your PSU's 12V output is so low.

I most certainly can suggest a PSU that isn't much.

And that is a bummer because you definitely have the ram for it you just don't have the horses

@thymanbearpig the in-game benchmark said i was averaging 24fps, but thats at very best. 99% of time its far less than that.

@bigshootr8 thank you, looks like im upgrading my psu!

I don't know a lot about troubleshooting, but I've heard of switching the video card to another slot, I'm not sure if that'd be worth a try.

I've noticed my video driver version is much less than yours? Yet everything tells me im up to date. Also my CPU usage seems very low.
