If Diablo runs at 640x480x8bit at 30FPS that should take somewhere around 9216000/s or roughly 9MB/sec from the CPU to the Voodoo card on the Mediator. Maybe in ideal conditions the PPC on the motherboard could write to the Voodoo something close to this speed-maybe. But usually we assume it's more like 6MB/s.

If Diablo is running at 16bit color depth this goes up to roughly 18MB/s-totally unlikely for the PPC on the CSPPC to access the VRAM on the Mediator this quickly.
Obviously this is not a problem with the slowest PPC card sitting on the PCI bus.
Solution: Cowcat updates DevilutionX to use Warp3D

If would be interesting to hear how a CSPPC+CVPPC works with DevilutionX.
