About speed, GPU is faster than 68000, i did a quick test having 1376 vertrex rotated and drawed on screen, with the GPU running on main ram, with no optimization, i doubt that the 68000 can do this...


Ah! A man after my own heart!!! Hey, what kind of frame rate did you
get just for shits and grins or was your goal to simple test the GPU?

...on the 68k doing this...

No...the 3D demo in the atari dev kit is what you get when you use the 68k....slooooowwwww!
One model at a frame rate between 10 and 30 (if its way back in the z plane).


Do what the 68k is doing instead with the GPU and drastically increase the speed!
Do that in main with the GPU and drop a few cycles here and there but zooooom!
Use the local for all that stuff anyway and do all the AI and other stuff out in main,
all the init and what not. the 68k is still fine to set up a level or game boot init.
Personally, I'd keep it off the bus(asleep even) as much as possible.

Jagmod is amazing! He has hundreds of cry decent sized objects (scaling ones)
on the screen at 60 FPS and the 68k completely stopped. There are some things
the 68k may be good for, but it aint in the main loop (usually)!


Sounds like JagMod is the official Jaguar "Mega Demo Master".

Just tell him to take out ALL user interaction and add some giant scrolling text with poor grammar, and he will be untouchable.

Gorf had a real gift. He made things that were really, really complicated sound really, really complicated.
