Do you believe it's possible to generate 4 medium resolution (800x600)
channels at 60 Hz on a Onyx2 InfiniteReality Deskside with 1 pipe, 2 RMs,
DG5-8 option and 4 CPUs?
According to the specs and using a depth complexity of 2 for low level
flight, the fill rate would be sufficient (230/388 Mpixels/sec) and the
polygon capacity would be large enough (11M/4/60 = 45800 polygons per
frame per channel -- 10000 would be more than enough). However, I'm a bit
uncomfortable with the idea of having only 4 msec to draw one channel
knowing the field of view would be 60 by 45 degrees.
I'd like to receive comments from system integrators as well as from SGI
programmers.
Thanks a lot.
