If you think that's bad, try writing 3D games on the MIPS without a MMU, FPU or a data cache. Welcome to Playstation programming. Admittedly it's got a direct-mapped scratchpad where you can drop temporary data and some really esoteric low-precision fixed-point matrix operators, but it's never -quite- what you're looking for. My last Playstation title saw upward of fifteen hundred lines of tightly tuned assembly before all the special effects were up to 60fps again. The Lego Racers team have had an average of one and a half programmers tuning their rendering engine for over a year now. I think at this point they're assembly from the BSP traversal on down. Next project's Windows, Playstation 2 and FreeBSD/Linux internally at the least. I'm finally a happy camper. _________________________________________________________ Do You Yahoo!?
