memory caching

[Tom]

What determines the cached memory? I am looking at the performance tab of
the task manager and it says total physical memory 2045, cached 1432, free
12. How can you turn this off? I am having a problem running quake 4
because it can't allocate enough memory to play at the lowest settings. In
xp it plays fine with my system which has an opteron 170 and an ati
x1900xt.

Vista uses all available memory for caching, but releases that cached
memory when another program requires it. If Quake4 is not running,
it's not because Vista is holding memory.

Have you installed the ATI drivers for your video card?

I have installed the latest drivers. It is something with vista that it
doesn't like but I am not sure what. I will try to run it in compatiblity
mode. The game launches and goes to the main screen. It doesn't get the
error until I try to load a game or start a new one. It gives the error
when the loading status bar is almost to the end.

It sounds like the game itself is allocating memory instead of the OS maybe
? Are you running it in XP compatibility mode ?
