Yes well basically my game crashes after about 10/15 minutes. The mods that i have installed are: LCPDFR, Tow truck, Police helper, Policing tools, Breathelising, Medical examiner and traffic flow. I also modded the police cars.

 

Crashes are normal when playing with mods, but you can lessen the amount of crashes by running the game as administrator, removing high-poly count cars, reducing the amount of scripts and reducing the in-game graphic settings. I have to commandlines for you, which you put in your main GTA IV folder. Create a file called "commandline.txt" and add firstly this: 

-renderquality 0 -shadowdensity 0 -texturequality 0 -viewdistance 0 -detailquality 0 -novblank -norestrictions -percentvidmem 100 -minspecaudio -novsync -renderquality 0 -frameLimit 0 -nomemrestrict

If this seems to reduce the amount of crashes you have, consider using this instead: 

-novblank -norestrictions -percentvidmem 100 -novsync -frameLimit 0 -nomemrestrict

If that didn't work, revert back to the previous one. Yes, your game will look bad with the first one since it forces the game to bare minimum settings. 

 

What are your computer specs btw? 

Also make sure Clip Capture is turned off (that option is found under the 'Game' menu on the pause screen).

my specs are: Processor Intel® Core i5-3470 CPU @ 3.20GHz, 3201 MHz, 4 core('s)

Please post your full specs. Also, did the commandlines work? 

Processor: Intel® Core i5-3470 CPU @ 3.20GHz 3.20GHz

Ram: 8.00GB

Graphics card: NVIDIA GeForce GTX 650

 

The command lines did make a diffrence, it now lasts about 10 minutes longer. However now i discovered that when i enter a car chase it crashes..

Does it still crash as frequently if not using modded cars? Did you follow the tip given by Original Light (Disable clip capture)? 

Yes I did, it was turned on so I turned it off. I don't know if it did make an diffrence and it doesnt make a diffrence if i use modded cars or not.
