Best speed using framebuffers

Hi.

I’m experimenting with a VIA-EPIA Mini-ITX with has a Trident Cyberblade
video chipset. I’m currently using a vesa fb at 800x600x32 to run a slot
type game. How do I know I’m squeezing the best possible performance for
this hardware? Looks like the tridentfb does not work on this baby.
There’s a epiafb driver avaiable but it’s too crude. Any tips?

TIA

Adilson.
