Hmm. My card has 256MB of VRAM (ATI Radeon 9800 Pro), so I'd hope
there's plenty of RAM. I have a RB app used for Zombies to create
human textures -- only a single model in the RB3Dspace and there's
still a hiccup.
It really depends on the number and size of the textures you have
loaded. I'm not sure how Quesa works, but it might just be that your
textures haven't been preloaded to the video ram.
I believe a 1024x1024 texture (24 bit) uses about 3MB of VRAM. 256MB
VRAM will give 85 of those.
If you really want to pack in the VRAM efficiently, I've read
somewhere about sticking a single large texture into VRAM and
texturing the majority of your models with that -- supposedly
speeds load time and avoids much of the RAM-VRAM swapping. Now that
I think about it, it's probably a trick best suited for consoles
with their fixed hardware requirements, but I think it's an idea
worth pursuing.
I might be heading that rout. It's the only way to combine an entire
environment to a single mesh while preserving its texture.
