what i would like to do is have gta 4 utilize the shared ram because it only recognizes 256mb which is my dedicated in all with shared i have 1383mb which would make the game run alot smoother and better quality is there any command line things that would allow it to use that or patches or something i am using the STEAM version of the game other system info and specs macbook 5.1 unibody os-windows 7 cpu- core 2 duo 2.0ghz vid card- nvidia geforce 9400m (prereleased drivers) 256mb dedicated 1383 total with shared ram 3.0gb
I don't know if this will work but you could try it however. First create a commandline.txt file in the folder where GTA IV exes are. Then add "-availablevidmem 5.4". The 5.4 is a multiplier that multiplies the amount of memory the game recognizes. So with 5.4 the game recognizes about 1382 MB. If it doesn't work, try a lower value.
thanks just to let you know yes it did work now my only problem is i need more ram to make it run a little smoother
