EF2000 seems comes with latest spd3d.uc (spd3d.uc inside contains header with "ELF" that reminds me apps on linux same or almost same header. Rendition developers is linux funs)))? all dos games comes with spd3d.uc so that means its dynamically linked as for example glide2x.ovl in dos 3dfx?
thare is Nascar2 demo that also have rendition support
there is rumors that if you copy spd3d.uc as spd3d.uc2 it allows you run on v2200 , need to check.
Formula 1 contains weird file winspd3d.uc
by googling "spd3d.uc" you can quickly find games , they all already documented here
tomraider demo can be played with verite card, its can be found on 3d blaster pci diver bonus disk
i also found sp3d3.voh file, looks like source code, or decompiled, in non readable or understanding form (
another idea is to change spd3d.uc from another game to descent2 , so maybe it fix purple color on s220 video card
