really sad but thats the truth....
What is the reason exactly? Context switching or just general 060 is much faster for 680x0 use?
Assuming the 040/060 have similar memory badwidths on the card (neither can make use of 64 bit access), the 060 has twice the clock, but also twice the cache to push.
Has anybody fully timed the context switches on both systems to see what the effect is?
-edit-
Now I think about it, I did actually time context switches on my machine (040 version) with some free source I found on aminet that manually did context switches in a large loop. IIRC, it was about 600 microseconds under warpos 5.
Anbody got a figure for 060?
