I'd appreciate suggestions for improving the graphics performance
of DEC Personal Workstations running Digital Unix.
Our users who typically run their apps on Sun Ultras
have complained that the DEC PWs are 8-10 times slower
on their benchmarks. They got a bunch of extra speedup
on the Ultras using an optimized XIL (I think) library.
Is this library (or an equivalent) available for the PWs?
But even without XIL, an Ultra1 is ~25% faster.
I think the PW has the PowerStorm 4D30T graphics card.
