Increase VRAM for games

I am playing GTA 4 with m15x. But when I want to increase the view distance, it says that my resources is either exceed or full that I have to lower some settings and free up the resources. But I want to increase the view distance while not lowering anything else. Is there a way to increase the VRAM in m15x?

 

How much vRAM and system RAM do you have?

Have you tried other drivers?

 

You can't change it.

And GTA IV is made of fail and buggy as hell.

GTA IV for PC is an epic fail. worst port from consoles ever (SLI? what's that?), and terrible optimisation.

 

My VRam ingame is set to around 500 but I have 4GB RAM. Why is that? Confused...

 

cuz your GPU has 512mb RAM

 

isn't the VRAM on consoles ALWAYS shared?

 

I thought that with dedicated graphics, the amount of VRAM on your card(s) was what you had? And something about system RAM being much too slow to handle VRAM duties. I could be wrong.

 

System RAM is not too slow to handle VRAM duties. The bus between the system RAM and the GPU is too slow to handle the necessary tasks. Plus, using that bus constantly for that purpose would slow down CPU performance significantly, just due to the bandwidth problems... (ever tried to access the internet when someone was using the full bandwidth of the connection you're on?... same idea. messages get queued (or dropped), and take a lot of time to get to where they're going)... overall, using System RAM for VRAM purposes is just a dumb move... that's why they stop you from doing it at a hardware level.

Chipsets with integrated graphics cards have more direct access to System RAM and are often significantly slower in performance than their dedicated counterparts... making their RAM Bandwidth toll less.

Maybe that's why Intel will never be able to touch nVidia or ATI in the graphics segment... hmmmm.

anyways, I will say yes, that with dedicated graphics the amount of VRAM you get, is how much you have. no way to change it. and 512MB is kind of the standard right now... systems with more than that are usually ultra-high-end desktops, SLI setups, or something of that sort.

 

OK, that makes sense. I just remember reading that it was rather difficult to use system RAM as VRAM.

Also, in SLI and CF, the VRAM is mirrored, as in two 512 cards do not equal 1GB of VRAM, but rather 512MB mirrored. Again, I could be wrong.

 

Hi, you do not need to increase your Vram just go games right click on gta4--> personolize--> modify the first option or add another with ("C:\Program Files\Rockstar Games\Grand Theft Auto IV\LaunchGTAIV.exe" -nomemrestrict -norestrictions -novblank -texturequality 2 -percentvidmem 100)
For me it is working fine,

 

So is GTA IV working, or no? I read in another thread that it was released prematurely and that people were requesting refunds for the game.

 

Working 100% for me on High in single player. During multiplayer there's the occasional crash.

 

That sucks. I already told my wife I didn't want it anymore.

 

well, single player is fine, for the optimal settings I get decent framerate with some slow downs at night driving. Whatever, maybe I will wait for the patch then
