Again, many thanks for your input. I already made a similar config for NewMode, allowing smooth rendering in an unpromoted mode and everything else on Voodoo.
I feel it must be possible to get everything on Voodoo with enough experimentation, but it could take a while to figure out and maybe not worth the effort.
On my A1200T/Apollo1260/64MHz, the Layout interface is smooth enough at about 800x600 and 16-bitPC mode. 24-bit promotion makes it jerky when manipulating objects. Anyhow 16-bit is quite suitable for the two color interface, eh?
I will continue to experiment and if I get the Rendering screens to work, I'll post it here.
Cheers,
