A lot of great changes here. Nice!
Although 3D Box still renders wrong for me, some textures not rendering at all (mostly the front, but different ones if you muck about with pitch, roll and yaw). I'm not sure if it was supposed to be fixed this build or not, but thought I'd mention it anyhow.[/size:257rdzbj]
Ignore that, it's just me being stupid and not checking the tracker (and the program) properly, (didn't check "3D Layering" in layer properties.)
Now to go try out xaudio timescaling.
