It will be slow, compared to an FFB card, but that's just because of the
way to memory controller works, and also because even though the SX/cg14
provides genuine TrueColour support, it doesn't have any acceleration
features over what the GX family provides beyond double-buffering.
There is no 3D hardware acceleration like the FFB's, AFB's, etc. provide.
Pity in a way, since having a circa-1994 high-end computing platform with
integrated TrueColour is quite a feat for the era. I think only SGI and
perhaps Tektronix had similar offerings then.
The best way to make a Sparc 20 more efficient for graphics is to use more
RAM and faster CPU's, since that takes a lot of the back-end load of the
memory controllers. Still, the SX is limited in it's performance, and you
can't get around that. 8-)
