How much video memory can a windowed app use?



Hi

I'm curious about a couple things. First, how much video ram can an opengl app use up "safely" when the app is windowed ( as opposed to full screen ). My app is a Cocoa app and has standard Cocoa controls alongside the Opengl display.

Secondly, how can I find out how much video ram is available?

And finally, what happens ( to the app, to the system ) when the card runs out of memory? I've had the whole system lock up, more or less, when I got close ( I'm guessing I was using up about 40 megs vram out of 64 ) -- I have to assume it was a memory issue, since dropping the number of vertices eliminated the problem.
