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.
You should be able to use as much VRAM as you want. Meaning, you
should be able to go far beyond the physical VRAM size as long as you
don't mind the degraded performance of paging.
What version OS and what graphics HW are you running?
