I just didn't know which S3 chip you would like to emulate. But, even
a basic S3 Trio32 is heaps better than plain VGA. Also, from your posts it
seems that you are very concerned on performanse optimization, which is
good, because the current implementation of VGA emulation is slow (and
also I believe it's not 100% VGA-compatible). It really drags the overall
performance of bochs and plex86 down. If you think that bochs is more
suitable for video emulation development, that's fine - it probably could
be easily transferred from bochs to plex86 and I believe that bochs will
be very important in the more distant future when x86 will become
outdated.

You can, for example via special calls to host's accelerated opengl
driver. I am not an expert in hardware 3D, either :-)

Slow video is one of major reasons that drags the performance down.
