what do you think about vram usage?
he was thinking (in windows) of using vram to cache stuff in but have no
idea if theres a way to manualy allocate that or if thats a good idea, or in
any way cross platform.
he was just noticing a similar type of game called nexus has like 80 megs of
art but only uses 20 megs of ram (with 30 megs of virtual ram).
any clue on vram? (:
