I do not know...
But I do not use such things as Allegro for my 3d projects. At least my current
project can not be written with Allegro. Allegro is a very common gfx library.
For *really* fast 3d game engine it's not suitable. Btw, Allegro doesn't support
Light Mapping used in Quake and it is not a very good thing for portal
rendering.
But please don't get me wrong!!! Allegro is a *very good library*, though.
As for math chip, it's very slow on 486s and quite fast on Pentiums. For
Pentiums I recommend to mix CPU and FPU instructions in order to achieve the
best performance. Btw, pairing on U and V pipes is also a very good feature of
Pentiums.
I strongly recommend you to switch to Pentium instead of old and slow 486.
Btw, why your 3d engine is so slow? Mine does 45-70 FPS on P133 in 320x200 mode.
I think yours is slow due to overdraw. Right?
Good Luck.
