I don't know any technical details, but AFAIK some emulators (snes9x? xmame?)
draw virtual screen on texture. And animation is smooth.

Please keep in mind that some applications update texture every frame.
Ok. I didn't understand the format that the card was expecting. A
large misunderstanding on my part. Thank you for clearing that up.

Let's say the texture loaded is 16-bit raw 256x256 texture.

At this "convert back" part, you just expanded the image back to its
original uncompressed size. No gain and you lose ima
So, I'm guessing that textures aren't loaded into memory before starting

Another wacky idea from the lurker:
I was looking at a voodoo? (yes, they still exist) review the other day
talking about texture compression and the effect it has on the texture
when finally rendered. While viewing the screenshots, it struck me that
the effects greatly resembled jpeg's lossines

Gareth, it's not a question of worrying.
Seriously guys, this kind of thing is the last thing you should be
worrying about, at least until you have a working DMA implementation and
a fully-featured Mesa 4.x driver...
Just my 2c.
