Use -memrestrict command line if you have stuttering problems

If you are experiencing frame speed fluctuations, please update to the latest video drivers, then use the -memrestrict commandline. Please do not use any other commandlines as they may override the effects of this one. Start at the lowest number based on your texture setting (ie. try them one at a time) You can try to increase the number until you notice stuttering again.

-memrestrict 188743680 LOW TEXTURES (256M Video Cards)
-memrestrict 209715200
-memrestrict 230686720
-memrestrict 262144000 MED TEXTURES (512M Video Cards)
-memrestrict 293601280
-memrestrict 314572800
-memrestrict 629145600 HIGH TEXTURES (1Gig+ Video Cards)
-memrestrict 650117120
-memrestrict 681574400

If you still notice stuttering with the lowest number, there may be a seperate issue with your system configuration.

Question

Ok, im sorry if this has been clearified but where exactly should i put these command lines in??

I have read that these commands should be put in soo many places i don't know anymore. one thread says make a command.txt and put them in there, another thread tells me to make a launchGTA4.bit and place them in there,yet another thread tells me to make a shortcut of the launchGTA4 and place the command lines in there, and finally in the actual steam shortcuts...

I have done all of the above, but im not sure which one is actualy working. Or maybe its a combination of them all...

where do these commands go???

it would help very much if all the variants of these commands were specified a bit more clearly.

For me the simplest way is to create a "commandline.txt" file in the main dirctory of gta 4 and write the commands in there. It works and I dont have to create extra shortcuts to the game.

I am getting a slow down over time, after playing for 15-30 minutes I start getting a stuttering. I goolge'd this and some people are saying this is cause by a memory leak, so I watched my task manager on my second screen while playing. The memory usage continues to increase until about 3.5 GB's are being used, then the game starts to slow down, and I have 8 GB's of RAM. I have tried all of these commands with no success, got anything else?


System:
AMD Phenom 9600 Quad-Core Processor
8 GB Ram (1066)
Geforce GTS 250 1 GB
Vista 64 bit (fresh install)

Thumbs down

i have C2D E8400, 8GB of DDR2 RAM, 2x 9800GTX+ in SLI, and after the latest patch GTA4 runs like crap on my pc. It lags all the time, and changing graphic settings to higher or lover, changing resolution or anything doesn't help. It just lags and the game is frustrating unplayable this way

Close the Rockstar Social Club, and use "LaunchGTAIV.exe" in the same directory as your commandline.txt (...\Steam\steamapps\common\grand theft auto iv\GTAIV) instead of steam to start the game. The arguments in the commandline.txt will then be applied to the game.

I had a similar problem as this with a very high spec rig, so if you are running into this problem and the above solution doesn't work, you may want to try running the game in windowed mode with my guide here: http://forums.steampowered.com/forum....php?t=1102048

since the last update on 13th of april the game began to stutter after 30 minutes of playing, becoming worse if i dont restart the game. it also began to crash if i drive taxi as passenger. despite that i always had problems with my performance because i have a 512mb graphics card tuned to 1,1gb. the game is first of all unable to detect the true performance of my card and if i use the no restrictions command i can put the details up but having graphics bugs if i do. the game takes too long to spawn objects (sometimes you drive, crash and then something spawns in front of you) i am also having problems with the LoD (level of Detail). sometimes i just got the far far away textures on things just in front of me, for example i am driving into a tunnel or driving downstreets but i cannot see anything because the street-textures stay the same height where i was driving before. so im practicly driving into the ground. got an
intel core2 quad Q6600 @ 4x2,4ghz,
4gb ddr2-ram (only 3gb used because i have win xp),
nvidia geforce 9800gtx+ @ 1gb
winxp sp3
... and i cannot even play on medium detail and textures without having it stutter and graphicbug around...
the -memrestrict command makes me paly longer without stutter but it doesnt help it at all

edit: i also recognized the "loading..." text in your loading screen at the right bottom doesnt reflect properly anymore to show the game is loading. the reflection effect doesnt move from one side of the text to the other anymore since the last update, it just blinks freaky
