Nurdle Posted December 8, 2008 Share Posted December 8, 2008 Ok before I start I'm posting my benchmark (auto detected settings)...... ------------------------------------------------------------- Statistics Average FPS: 45.58 Duration: 37.17 sec CPU Usage: 55% System memory usage: 85% Video memory usage: 96% Graphics Settings Video Mode: 1280 x 960 (60 Hz) Texture Quality: Medium Render Quality: High View Distance: 25 Detail Distance: 37 Hardware Microsoft Windows XP Professional Service Pack 3 Video Adapter: NVIDIA GeForce 8800 GT Video Driver version: 180.84 Audio Adapter: Sound Blaster Audigy Intel® Core2 Quad CPU Q6600 @ 2.40GHz File ID: benchmark.cli Retail version of GTAIV ------------------------------------------------------------- My problem is that GTAIV tells me that I only have 483mb of video memory, but my 8800GT has 512mb. I know there is a command line to alter the amount of video memory you have but I can't seem to get it to register 512mb. Anybody else suffer from this problem and know what setting I should use for the command line? I know this isn't going to fix framerate issues etc but I would like the game to use the real amount of video memory I do have. Nurdle Link to comment Share on other sites More sharing options...

Nurdle Posted December 8, 2008 Author Share Posted December 8, 2008 http://www.gtaforums.com/index.php?showtopic=381121 Already read that post and it isn't really constructive now is it? Just a copy and paste from the ReadMe.txt file. Anyway playing around with the command hasn't helped at all. First I tried "-availablevidmem 1.0" which gave me the exact numbers as before (483mb), Then I tried "-availablevidmem 512" which reported a whopping 1777mb of video memory!

pinkisthenewblue Posted December 22, 2008 Share Posted December 22, 2008 Its a multiplier, e.g. -availablevidmem 2 will give 2 time you;re video mem. 512 will give 512 times your mem - but the game locks around 1800. Link to comment Share on other sites More sharing options...

I have same pc like you and i have 438mb too so this commands are worth trying? Link to comment Share on other sites More sharing options...
Nurdle Posted December 22, 2008 Author Share Posted December 22, 2008 I have same pc like you and i have 438mb too so this commands are worth trying? I tried for a while to hit 512mb but it's not possible. GTA IV seems to cap your memory at 90% and leave 10% vidmem for overheads or something to that effect. For me the biggest impact on my game performance was dynamic shadows (Shadow density), Turning this to "0" saw my framerates improve and generally become more stable. I now get 30-40fps practically all the time. No more sudden drops at night and when raining etc. Link to comment Share on other sites More sharing options...

No one who plays GTA IV sees all their VRAM. My Card has 768MB an I only see 748. This is normal and not being able to use 20MB or so is not going to effect your gaming experience. Forcing the game too see more VRAM isn't going to do anything, you even said so yourself. In fact it might even cause more problems for you. If you really want to use the cammand then use it like this. -availablevidmem=1.0 will use all your VRAM like normally. If you use 2.0 it will double the VRAM available. So I would say use 1.1 Edited December 22, 2008 by Pixelated Link to comment Share on other sites More sharing options...
