Hello, so i made a topic about this some months ago, but i explain very bad in it so, hope someone can help me out.

 

I play with some mods for callouts, and common mods like vdH Police Helper and some custom vehicles (Just emergency vehicles, police, ambulance, firefighters and the speedo). The game runs great, i have low fps but that doesn't matter, is my bad PC. Right, so when i play for some reason the map starts dissapearing, and no, i don't mean the normal bug when you don't use the commandline, so i load my saved game, i go to the closest PD, select any character (i forgot to say i have UK police and vehicles are from the UK mod too, but this happens with a lot of cars or models, is not the mod itself), i select a car and then i start playing, sometimes this bug happens in a chase, sometimes it happens randomly, sometimes i request an heli and it happens too, but i don't know the exact reason. Well, hope people here can help me solving this thing, i can't try nothing by myself now because i don't really know what's the problem. I let my PC specs (they're bad but they can run the vanilla game very nice with the commandline that i'm using and with all the mods i'm using it just drops some 5 or 8 FPS so i doubt that my specs are causing this problem), and my commandline.txt.

PC Specs

RAM: 4,00 GB (3,88 available)

Proccesor: Intel(R) Celeron(R) CPU N2808 @1.58 GHz 1.58 GHz

System: 64 bits

OS: Windows 10 Pro

GTA IV Patch version: 1.0.7.0

 

 

Custom vehicles (Especially for GTA IV) are usually the culprit for this. The high poly models you may be using are allocating too much of your video memory so it stops rendering the map.  This is amplified during pursuits because not only is your game processing the AI, but also spawning in more high poly models as back up. Your best bet is to either remove the models or add them one by one and see how many your game can handle. Judging by your specs I'm assuming you don't have a dedicated GPU? 

 

Note: This is personally what I have found over the years playing GTA IV, there may be many other culprits but for GTA IV with the map disappearing this is the most common issue I and many others have ran into.

Well, you're totally right, i saw a video about this and i understand that, but i don't understand the question about dedicated memory, if you're talking about the availablevidmem in the commandline, i put 40.0.

It's like 2000 mb or something like that in the game, let me check.

I'm speaking of the actual physical amount of dedicated video memory your graphics card has.  Example: Nvidia GTX 1080Ti comes with 8GB of dedicated video memory for it. The commandline you are using is great to make the game ignore limits of the memory (Although this can cause memory bleeding), however it still depends on how much memory your graphics card actually has.
