i would like to add, that my english is not that good so i would be able to explain everything to you in detail...

just want to CONFIRM that this actually WORKS...

so if anyone who is GOOD in writing FAQS would try this - he will be quite surely able to help you guys through this process...

After doing this, you won't be able to access your graphics menu anymore. When you try to exit the screen it should ask "Do you want to apply settings?" If you say No, you get stuck in an infinite loop. Which is why he told you to set everything before applying this 'tweak'. A buggy graphics menu means it's working.

Yea thats the down side if you go to the graphics menu ur stuck ctrl alt delete. lol.
But thats ok, once you have it set happily you don't really needa go back there.

And currently for anyone interested im fiddling around with motion blur. I wanna get the motion blur working but so it activates at higher speed. Cuz I like it when im driving, but when im standing still/running around I don't like the textures being butchered to fuglyness.

sure i know , just my crappy english , i did it right

What's the multiplier for a 4870X2 2GB?

I cranked up the graphical settings to the highest settings and it's using then around the 1440mb of vid. memory. This outlined in orange, but anyway....

[TeaBeeCZ]

I've just managed it but haven't tested for longer time, I'll see if there are no more "all of a sudden" missing textures after some playing time. I will report...

BTW super idea, man.

Well if you have 2048 VRAM, and its taking up 1440. Id say try:

-availablevidmem 0.705

See if that will do the trick.

What you mean with "motion blur" ? How do you activate it? Because if you are talking about that "P" blur that is sh*t, just make things worse

Exactly, using P looks nice when your driving fast but terrible when your walking around. I'm gonna try to make it so it blurs when your going fast in your car. But not blur at any other time, I'm sure fiddling with the settings for the mo-blur in the visualsettings.dat can get it just right ill let you guys know if i make any headway on that.

Let's say you do this trick...and it works. (with say -availablevidmem 0.705)

Is there any reason you couldn't change your available memory limit to even less, say .25 (or 25%) and get even higher performance?

@MonkeyMhz

my commandline.txt is blank , i start the game , set the resolution to 800x600 (60Hz)

in the memory line stands : 676/739 (i have 8800GTX)

shut it down

then i edit my commandline, so it looks exactly like this : -height 1050 -width 1400 -availablevidmem 0.916 and save it

i start the game : go to the graphic settings , and the resolution is set to 1400x1050 and im way over the video memory XXX/677

- so where is the problem ?

[DJ24966]

No matter what the menu goes back to 1024 * 768... and performs even worse than before... I was getting 15 fps before, now can't even hit 10..

You must limit to some quantity of memory that meets one of the resultions, like 640x460 or 800x600. What is happening is that the tweak denies the capacity of the game of scaling the maps, which consumes more memory; so you need to limit it to some memory quantity need to run at certain res.

Make sure you don't have -norestrictions, your game should not be able to go much over your GPUs VRAM, unless if you have no restrictions or nomemrestrict. Which would cause this whole process to not work. Ill add screen shots on what to do when I get home, incase if your mis reading the instructions (I know its hard to explain).

Yea, you got it. Your just tricking the GTAIV system to thinking you don't have enough memory to move your res up, so really its moving the res up forcefully but in game it cant so it leaves you with the reflection maps of the 800x600 setting.

i thought the in game options were supposed to say 800x600 even though the resolution was whatever you put in the commandline, but im still seeing this



i'm only getting about 14fps with this setting, am i doing something wrong or is my computer just beyond help?

That shouldn't be happening set your available vid mem to 0.5 half your 512. Now go in game, set it to 800x600 then use the rest of your memory budget on draw distance. It should not let you exceed your memory size. Now when you exit and add -height -width. With your desired res, when you go in game, it should still say 800x600. If not then the VRAM must be increasing cuz 1024x768 takes more VRAM on the counter than 800x600. And if you don't have norestrictions or memrestrict on then it should not let the VRAM go much over. If your VRAM is shooting over like 300/243 then obviously you have no restrictions on somewhere and you must get rid of that.

True, but again GTAIV gave u about 20mb *space* over the counter. So limit ur GPU a bit more so it wont have the budget to go over 800x600. The difference from 800x600 to 1024x768 is a couple megabytes, so its tricky to get ur GPU to limit so the game cant go over 800x600, but if u keep lowering your GPU limit you will get it.

Well,

In my case i hate the lower quality of textures etc, so i probably would restore that.
Also, after 10 minutes i get a BSOD and i have to reboot my pc manually.

So i think i have to tweak the available vid. mem.

The says i have 1011mb by default. 1011MB is not the "official" 1024mb.
Let's see what happens when i use 2022mb instead of 2048mb, with a slightly different multiplier.

Well yea use the multiplier thats on your cards exact mb that the game detects, you have to inch it down till you get it right.

Btw what does the BSOD say, cuz this should not in anyway be able to cause a BSOD. And also when the game says 800x600 when your running at a higher res. Its not decreasing the texture quality. I believe the things that scale with resolution are the shadow maps, reflection maps, environment maps, and possibly some shaders.

Same as this guy, followed the instructions, the command line is exactly : -novblank -height 900 -width 1440 -availablevidmem 1.83 -refreshrate 70

Its showing the resolution in game, and over memory: (Uses 890 for 800x600)



I'm not stuck in the settings screen btw, the options can be changed and such without problems, and theres nothing on removing memory restrictions.
