When using HW TCL in Tuxracer or PPRacer (that is essentially the same

can see that there are problems with light reflection in those places
where there's ice (for example in the first stage that is full of ice
pools ) .
You mean the flickering? That's probably Z fighting, most likely a
problem in the game itself. You should bring this up with the PPRacer
project, now that there's active development there...
No, this is a result of the tcl fallback used for the GL_SPHERE_MAP
texgen (it is z fighting I guess). Someday we should figure out why it
doesn't work correct in the first place probably (if you kill the
fallback, you can clearly see it's not quite correct in ppracer), though
it wouldn't hurt to make the fallbacks work better neither (r100 has
afaik the same problem, and it can't be fixed by not using a fallback
since it doesn't support GL_SPHERE_MAP texgen).
