It's much faster to keep your textures within the following dimensions as
they fit in the texture cache and only need to be read from VRAM once.
Furthemore, drawing all polygons with the same texture in sequence is
advantagous.

4-bit 64x64 max
8-bit 32x64 max
16-bit 32x32 max

As for speeds, it shouldn't be too hard to set up a test program with
textures at different bit levels. Then time how long it takes to display,
say, a thousand of each.

Ok here are a few questions for NY gurus :)

Why does GetTPage need the semi-transparency rate?

How to poke in VRam (other than Load/StoreImage: I just want to poke a
byte/w/dw, hopefully quicker than by drawing a line/box/sprite)?

Are 16bit sprites faster than 8/4bit ones? (I think they should because
they do not use a palette)
