-reservedApp 0

Will somebody please explain what it does. Nobody wants to do so in the extreme texture pop-ins topic. All I know about it is that it shouldn't be use with 32 bit OS's.

 

I Googled it a couple times and got nothing. So whoever explains it will be world famous.

It is explained in the thread, but it's a bit crowded now, so you are probably having trouble finding it.

 

This definition may not be perfect, but is the gist of it as I understand it:

 

-reservedapp controls the amount of memory that is left available for other applications. Adding the zero effectively stops other programs (which windows may be running in the background) from using up memory as GTA IV is in use.

If your setup was stable with Patch 5 and you are seeing excessive popping on high end rigs, try the following commandline:

 

-reservedApp 0

 

Do not use any of your old commandlines in conjunction with this when first attempting it; try it on it's own first and let the in game memory management handle the rest. This should NOT be used on Vista/Win 7 32 bit*. Same goes for High Textures in general, there simply isn't enough memory available on 32 bit Vista/Win 7.

 

GTA IV and EFLC are Large Address Aware, on 32 Bit Vista/Win 7 you can use the bcdedit command to enable 3GB memory address space which will allow the games memory management to behave as if it was on a 64 Bit Os. Do not attempt this if you've never heard of this before, it can cause your system to become unstable when using other software.
