[NOTE: THIS GUIDE WAS MADE AND WAS TESTED ON MY OLD COMPUTER WITH 8500 GT].

This guide is only for Nvidia Graphic Cards. (Doesn't work well on ATI, sometimes it doesn't work at all).

Make sure you have the latest patches installed for gta iv and social club. The best patch in my opinion that works best is the 1.0.3.0.

NOTE: This may or may not work for you, depending on how old or fast your RIG is, it worked for me and improved the FPS rate from 19 to 40.

WARNING: Do step #3 at your own risk. You may screw up the game if the guide is not followed properly.

There are some cards that have more trouble playing GTA IV, but luckily there is a solution without overclocking your graphics card! Since my gaming PC wasn't fully done back then, I decided to look for a solution for my 8400gt, the game lagged like crazy, I was getting around 19-21 fps on all low and on high around 5-9 fps. It did show an improvement form 32 to 46fps!! At the end When i finished I ran the game and from 21fps I was getting an average of 32 fps! (30-32 on the outside and 32-40 on interiors).

Please follow the steps CAREFULLY!

1. First download this, Its a command txt file. Place it in the game directory and don't edit the file! For example: C:\Program Files\Rockstar Games\Grand Theft Auto IV.

2. Once the command file is in the game directory, download this other one and place it here X:\Program Files\Rockstar Games\Grand Theft Auto IV\pc\data\cdimages
Don't forget to make a backup of the original file!

3. Download this other file. Pay attention! Extract the Contig file, cut or copy the contig.exe to the game directory, X:\Program Files\Rockstar Games\Grand Theft Auto IV and make a shorcut to the desktop, should look like this.


[Open in a new window for higher resolution].

After you have the shortcut right click it and go to properties, in the Target field, add a SPACE at the end then -s like this.

[Open in a new window for higher resolution].

Then click apply or OK. On the contig shortcut on your desktop run it, you should get a CMD box and it should be done in 5-10 minutes depending on your computer. Don't close the window!

4. The last thing you are going to do is get hacked Nvidia drivers(new ones) it seemed that the drives were locking the FPS at 19-22. With hacked drives the FPS are free and unlocked meaning that there are no restrictions. You can download it here, just choose your graphics card series or model and download your driver.

Hope this helped.. It did for me i gained 17 FPS! If you need any help please leave a comment! :)

Here is a screen-shot getting 42 FPS without blur on a Geforce 8500GT.

Hey r4fay can u tell me what does 'Contig' do? And the new gtxd.img file has reduced graphics? I am asking it because I am getting 30 FPS on everything High but I want to improve my FPS but dont want to compromise Quality. Haha that's why I have put all on high. BTW I have GTS 250 1 GB. Reply soon

Like reaper said, the Contig does that function. The new GTXD.img reduces the texture quality a bit. Increasing your FPS rate is just useless, movies run at 25 FPS, so gaming at 30 isn't a pain.

Ok. One more thing the commandline file u provided contains these three commands -memrestrict -availablevidmem -percentvidmem. These are incomplete, there are certain values along with these command like with -memrestrict after that u have to write a number according to ur video card memory like for 1 Gig card i have used 629145600. Then it becomes -memrestrict 629145600. This is also the case with the other two commands although I am not sure what they are. Something like -percentvidmem 1.05. So i think u have missed a step in ur guide.

Ok, smarthead. The Contig file is there to auto-adjust them, when you run the Contig file, it takes some time to identify your hardware and set the valves according to it.

Oh ok I didnt know it because I thought Contig only defrags. now I think I should use Contig because I was always confused about the right values of these commands for my system.

EDIT: Ok, smarthead, I copied the commandline.txt file to the directory and then Contig file and then made a shortcut and put a -s at the end and ran COntig. It ran for around 2 mins and closed but it did NOT set any values in the commandline.txt
