Hello, just getting set for Bioshock here in the next few days and I just reinstalled vista 64bit. I noticed it's using about half (if not more of my 2gb of ram) i've been reading the some posts about it and it doesn't look like shutting off superfetching is much help. So i'm just curious from a gaming viewpoint if I need to be worried much? When I launch a power hungry game like bioshock am I going to have to worry about memory issues/framerate drops?

Thanks.

You shouldn't have to worry... Vista allocates RAM for program usage, but relenquishes it if it's not needed.

Vista uses RAM to its full potential. Just because you have little left doesn't mean a thing. Close a program and the memory use barely changes.

As he said, it allocates memory to programs.

Previously Windows would leave X amount of memory "free" - like having something sitting around doing nothing until its needed for a new program. Now, the memory is all working and realloates as needed.

Very efficient use of the memory and a nice job on my part of over explaining. ;)

This also give some issues as if you run more applications at same time and switch from one to another for while and then switch back, you will get realy bad performance and high disk ussage as it start reading all data from swap back to ram and it doesnt matter if other application dont need resources used by other one.
This is what realy bugs me as for example when i swith from EQ2 to desktop to read som web or watch some video whitch dont require much ram, and after some minutes switch back, game is unusable for some time whitch can reach 2min+ in some cases. (2GB ram)

I would not call this very efficient, its just oposite.

Sounds more like your system setup and EQ2 than with Vista. Tabbing out of games has always been odd on any OS I've tried it on.

Vista can flush its RAM cache very quickly, and I don't see the desktop/video/web as being particularly demanding, so chances are there is either a problem with the game or the video card driver. The video card should switch memory from the game to Aero and back smoothly, so you should check to see if the video card drops back to 2D mode when alt-tabbed (as it should) and try running the game without Aero enabled and test alt-tab. You could also try increasing EQ's priority in the task manager to see if that helps it regain focus more quickly.
