My PC is not the best:

or specs here: http://www.newegg.com/Product/Produc...82E16883113088

Video card is a 4670: http://www.newegg.com/product/produc...82E16814102855

However there seems to be various tweaks and such for GTA IV.

If I can push 30 FPS. I'll be happy. While the game still looking good.

I also own the Steam version of the game.

I've read some tweaks at the GTA steam forums. I can't seen to notice a big difference.

Thanks.
 
You have a 4 core processor which is good but it's clocked very low and your videocard is killing you. GTA 4 needs a lot of video RAM.
 
I used some commands added to the launchgtaiv.exe to make mine run quite a bit better. Using these commands, the game is tricked into thinking that your video card has less RAM that it actually does. After you add the command to force the game to run at your desired resolution, the texture levels will run at whatever resolution you set in game. So, if you set the resolution to 800x600, you'll get low texture levels. This is the only way to adjust the texture levels.

These are the commands that you need to add to your launchgtaiv.exe:
-height 1080 -width 1920 -refreshrate 60 -availablevidmem 0.75

Of course you'll set the resolution and refresh rate to whatever you're using. The availablevidmem command sets the amount of your actual video memory the game is able to use. So setting it to .75 allows it to use 75% of your video ram. You'll have to play around with settings to see what runs the best and to see how much of your video ram you want to give to the game. When you find the best performing settings, you need to adjust your availablevidmem to make it so that your available memory in game is very very close to the amount of memory that is being used by the game so that it will be forced to use the low resolution textures.

If you have trouble following my directions, here's some more detailed instructions:

Using these tweaks, I went from getting low 20's to 40's. That's still pretty terrible, but it's playable. I have a q6600, 4GB RAM, and a 1GB 4850 so it's not like a game with this quality of graphics (not so great) should run like this on my system (I get close to 100 FPS all the time in CoD 4, around 90 or so in Fallout 3 and Oblivion, and 80's in BFBC2.. all of which look much better than GTAIV). The engine that GTA IV uses has always been horribly optimized. It even ran about as terribly on consoles as it did before I did the tweaks on my PC. After doing the tweaks, the game was very playable for me.

Having a quad core (any) and a 4600 class video card makes for things to be really playable. A basic Phenom 9550 was as fast in GTA4 as an E8600, so your quad is right up there. To be honest though, GTA4 doesn't really run very well on good hardware. My quad is quite a bit faster and my video card at times has theoretical double the potential power (double SP near same clocks, double memory bus) as a 4760, yet still get around 25-40fps with everything on high.

I would put everything to medium and reduce distance visuals. That way less Vram is being used (main problem with the 4670, it's pretty much a 3870 with less than half the bus with) and your CPU is being pushed more.
 
Well that blows. I picked this GPU as it was recommended based on hardware I have from a thread I made on these forums. I mean I know I should get a faster CPU & bigger power supply. However I'm not looking to play the latest cutting edge games.


Would using Overdrive be of any use?
 
Something is up......

No matter how low I make the settings in GTA IV or like Left 4 Dead 2 even. The FPS doesn't go past 30ish.

Tried messin with Over Drive too. No difference.

That video card is well suited for the rest of your system. GTA IV, however, IS one of the most demanding games on hardware right now, so you shouldn't expect spectacular performance. That's just the way it is.
 
just turn down the draw distance, since there are building everywhere you won't notice it.
and turn of shadows completely. I went from 40FPS to a rock solid 60FPS just by turning off the shadows.

On my system with a 980x and three 5870s in CrossFire the framerate will still dip below 60 fps (I play with vsync on) at various times.
