With 25 mhz 030s (GVP, A3000s), you can beat the blitter using the processor for lines and polygon fills (30% and 100% faster, respectively). A3000s are even faster if you use 32 bit writes to chip ram. I achieved a 25% improvement on the A3000 over the A2000 w/030. I haven't tried comparing 32 bit block copies against the blitter, perhaps someone out there has... John
