Your system would barely play it on low setting and with that E6750 it'll just be barely mediums setting. This game was made for Quads. Guy I advise you to read up on the game and any other newer games.

I got GTA4 for my spec below, and let me tell you the game runs like slideshow and is BADLY CODED for normal cpus, hence it needs a quad core cpu.

 

Geometrically speaking, the game isn't that demanding in graphics in terms of polygon counts and all, however since it loads and render the WHOLE WORLD including inside of buildings even when u can't see it on screen, its not designed efficient enough. I would've much prefered having a separate loading screen like san andreas for going into buidlings. Also Putting the game on LOW setting and High setting made no graphic performance improvement nor hits on my PC, its just my CPU thats struggling at 99% load ALL THE TIME.

 

GTA IV was for consoles, hence the codes are written to run on consoles, i suspect GTA IV isn't recoded for PC, instead its simply emulated, hence it explains the enormous CPU load...

 

GTA IV for PC = epic fail

for some reason they assumed everyone has a Quad Core Monster

Hey guys, i have been though a mill getting GTA IV to work on my pc. first of all, make sure you have windows xp with sp3/ or windows vista with sp1. because it wont work withouth either of those. and the game is very difficult to run. mainly because when gta IV designed the game, they actually didnt do such a great job. but! you can make the game run alot better like what i did. also you need to download a cache booster. especially for people with only 2gb of memory like my self. but before i tweaked a little bit, it was crushing my gtx 260. and using all the memory!

 

GTA IV PERFORMANCE TWEAK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

Theory:

Now my theory was that, if you have a memory limit on, and you enter a resolution in the command line that is unable to be achieved with that memory limit, it will still put you in that resolution, but the quality scaling will not be implemented. Therefore no disappearing objects/textures, no long or noticeable pop-in's, and less/no lag.

 

The trick is implementing the higher resolutions with you preferred graphic settings, by limiting your memory to just barely include the options you want, and then you force the resolution.

 

Steps:

 

1. Get rid of -nomemrestrict or any current commandlines you have. Run the game and let it die. When you run the game, go to the graphic options, turn your resolution to 800x600 or 1024x768 or whatever you want the reflection maps/resolution based quality to be at, I did 800x600 mainly because it looks simular to the rest and will give you the most performance. Use the rest of your memory budget in draw distance.etc.

 

2. If you cannot acheive the graphical settings you want with your currently memory budget do this next step. If you can, then you can skip this step.

 

make commandline.txt or append -availablevidmem (multiplier):

This command works like this, say I have 256mb vram. -availablevidmem 2.0 would make it say I have 512mb vram, its a multiplier.

 

So for getting our settings as we want it lets make a budget of 512mb vram, so -availablevidmem 2.0.

 

Open GTAIV, set resolution in the ingame settings to 800x600, set rest of the options to whatever you want (be reasonable).

 

Now continue to the next step.

 

3. Now you have your game set as you want it, but in a f-ugly resoltion, but we will fix that. Next step is to trick GTAIV, even people with 512mb graphic cards or even 1gb, this is even useful for them.

 

One of my buddies with a 8800GTX loves this tweak because it allows him to get much higher frames with very little to no graphical loss.

 

So now lets say all our desired settings ingame @ 800x600, use 650Mb. Ok. But say were now using a 1GB card so it says 650/1024Mb. This is a problem now because if we force -height 1080 -width 1920. We will end up with our ingame options changing to 1920x1080 giving us way more slowdowns because R* starts using that dam scaling reflection maps.etc with resolution.

 

So what we need to do now is limit the memory GTAIV sees to exactly the amount to run our game in 800x600 (or whatever quality refection maps.etc you want) with our desired settings.

 

So lets go back to our dilemma, we have a 1GB graphic card and the game only takes up 650mb with the settings we want in 800x600.

 

We can figure this out by doing some simple math.

1GB Card (650mb desired settings): 650/1024 = 0.635 (its 0.634 but give a tiny bit extra, just like a couple megabytes).

 

So you would use -availablevidmem 0.635 that would make the game detect you only have 650mb ram which barely fits the features you want in 800x600.

 

So now once we have figured that out your commandline.txt or your shortcut appending should look like this (depending on what resolution you want/your vidmem.etc):

 

-height 1080 -width 1920 -availablevidmem 0.65

 

and maybe you add stuff like (-framelimit, or -noblank or whatever).

 

*BUT DO NOT USE ANY UN-RESTRICTION (this includes the nomemrestrict and norestrictions or anything like that)!

 

4. Now when we start up our game. We will be in our desired resolution, and when we look in the game options it will say 800x600, even though we are in a way higher resolution and all your settings will be how you want them and your memory budget will be exactly the right amount or similar like 650/650 or 742/746.etc

 

Funny thing here you wont be able to go back cuz it will detect your memory budget is to low and the game is forcing a higher res, so you might not be able to leave the options screen now, so alt tab, and close the game. If all your settings looked right and it said 800x600 but was clearly in a higher res. Then you did everything right, if not, go retry.

 

5. Now restart the game and play. Yay, good fps, cheated GTAIV to not up the reflection quality with the resolution.

 

Additional Speed: If you happen to be running Vista x86/x64 and you have a directx10 capable graphic card. Do what elecg2 figured out. I tried creating empty/easy HLSL shaders and putting them in GTAIV to get rid of shadows and stuff but that didn't work.

 

However by doing what elecg2 tried, I got a huge performance increase,

 

Go to GTAIV folder, go into common, then shaders.

 

Backup everything in there <- !!!

 

Then copy the contents of win32_30_atidx10, and paste them into win32_30_nv8. Or just rename the folders, whatever makes you happy.

 

That gave me a significant performance boost and I have no graphical problems or abnormalities. Try it, if it causes you problems or decreased performance then just put it back to normal. With these steps you can get your game running beautifully in no time, or at least better than before.

 

Enjoy.
