Uhhhmmm??

Hello everyone,

So I was going through my properties and I came across this...

Is this normal? Why would Windows be allocating another 767MB to my graphics card? It already has 640MB! It doesn't particularly bother me but I found this pretty interesting, can anyone think of what would cause this (assuming this is out of the norm)?

I think a better thread title than "UMM WTF GUYS" would've been

"8800GTS stealing RAM?"

It's not as obnoxious as you make it out to be, you are right that I could have had a better title though.

Heh, I didn't know the 8800's took advantage of Turbo Cache. Search around a little bit, there should be an option to turn off Turbo Cache, that will stop it from stealing system RAM.

Like I said, it doesn't bother me that much, I'm sure it benefits from that extra RAM so I'll leave it like it is, but I just find that odd, as it's not advertised that it has that feature or anything like that.

My laptop's 7900GS Go does this same thing. It's a 256MB chipset, and it borrows another 256MB system RAM for no particular reason. I don't think Aero needs 512MB of video memory. GIVE IT BACK!

(oh and the thread title could have been a bit more descriptive)

I like your title...

That's exactly what I said when I saw it .

MY gts doesn't do this... Vista glitch?

AFAIK most laptop graphics cards do that, and I'm sure Aero does use that much RAM because, it's a total RAM hog =|. Yes, I know the thread title could have been more descriptive but I can't change it now so... =(

Waaaaa?

Vista now has virtual graphics memory, to better support multitasking of the graphics subsystem. YES, this is normal.

See here:

Opening up the video card to more applications will require Vista to give the GPU more system resources and allow applications to share the hardware. The biggest change for game developers will be virtualized memory for the GPU. The video card will now have its own space in system RAM to store information that can't fit on local video card memory. High-end video cards ship with 256MB or 512MB of memory, but games can still use the extra space in system memory to store large chunks of information, like textures.

And no, this is not TurboCache / HyperMemory - those are controlled by the video driver, not the OS.
