Hardware/software relationship - 64 bit

What I was convinced the scheme was that the GPU processes all the mesh data and textures but that the video memory is shadowed in RAM for direct access by the CPU but the order or approach there doesnt matter as much to me as does the effect of video memory on application space. Does the video memory take space from the available space for the application execution? If I have 4 GB available for the application as Vista dictates then does shadowing 4 GB total video memory leave me no room to execute the application? If so you would think the application would crash immediately with an OOM (out of memory) error but I might be misunderstanding how this is supposed to work. Thats how I came to ask my question.

As said on 64-bit subsystem this shouldn't be a problem. Btw it's a very bad idea to buffer textures to system ram it's a performance killer.

Thanks but thats what I want to know exactly is how it does work? I guess Im not being clear enough.

I guess you should consult your hardware dealer about possible compatibility issues before splurging the dough. Your configuration is probably at the top 1% of AH playerbase if not higher so regular users never have to think about that kind of problems.

if you are using onboard video then yes it does. you have a separate video card with its own RAM, so no it doesnt.

This would not be entirely true if it was a 32-bit OS. But since it's 64-bits the OS can allocate memory way more freely. The single 32-bit application will still have it's own 4gig max box but AFAIK video etc. peripherals do not need to be included in that (in 64-bit OS). They can use a separate memoryspace and the app will see the full 4Gb.
