- splitfree require dbuffer, PC/Amiga have that... but I dont think
- ethier do it in 'windows'. SGI do window dbuffer in HW using overlay
- planes so require 24bit+xbit to do 12bit splitfree anim.
- They have a vsync signal, but this dont do much for rastersplit free
- anim...

- quadruple buffer or more would be even better :)

- opengl support Vblank, and run on sgi/pc/... A pc card should be able
- to send an interupt.... The card driver /os can act accordingly.

- : already had (vblank & stuff) into PC hardware _and_ the OSes (win, linux).
-
- I dont know PC HW , but Dbuffer is what I would go for... BTW I read
- that the 'majority' of amiga nowdays dont have a vbi anymore :)
- Well they have the native video one, but since its not used it mean
- nothing.
-
- The VBL mean nada for splitfree anim, you can as well use a timmer
- interupt derived from the video mode timing.
