1) If you want to play the games that support Warp3D, then you don't want to play them in software mode. If you don't want to play any of the Warp3D games then not useful.
2) No, there is no Radeon Warp3D driver, this needs to be written or ported from OS4.
3) A Voodoo3 in Warp3D mode will be 2-4x+ faster than a Radeon in software mode and look better too.
Pity, under OS4 or MorphOS the Radeon would dust a Voodoo3. And both of those OS' support Warp3D funtionality with the Radeon.
Anyone know why there isn't a Radeon driver for legacy applications?
It seems kind of dumb considering it shouldn't be that hard to backport.
In fact, the R200 drivers under both OS4 and MorphOS are so mature that they perform really well.
Many MorphOS users didn't move to higher cards when the R300 drivers were introduced because everything above the R200 (under MorphOS) isn't W3D compatible.
And the performance gain was less than you'd assume.
Still, the Voodoo3's performance isn't that shabby.
It beats the other solutions (except for the previously mentioned Radeon).
