I've looked at the cube map part and some things don't quite work well. In
particular, 3 tmus and cube maps don't mix too well. Apparently, we're hitting
some hardware limitations there. For instance, if you run ut2k3 with 3 tmus, it
will look very wrong, and after that you're stuck with completely broken mipmaps
until you reboot! I've hunted this down, it's because the
TXFORMAT_CUBIC_MAP_ENABLE bit is still set, and if this unit is not enabled, it
will never get unset - this breaks mipmapping on either unit 0 or 1 (or both,
dunno), despite that the unit isn't actually enabled. That could obviously be
fixed, but I'd bet it doesn't work if the unit is enabled neither...
I'm wondering if the 3tmu patch was actually correct, can the radeon do
trilinear filtering simultaneously on all units? And if not, on which units can
it do filtering involving mipmaps simultaneously? And what about trilinear on
some units + cube mapping on others?
