Multi-texture in 1.30

[redvex 0]

I'm playing opf 1.30 on my pc (ati rage fury maxx)

and on a mmy friends one (nvidia tnt2 32 M sdram).

My framerate is very higher though he has a pIII 800 and I an Athlon 600.

But the point is that when he switches on multitexturing,

the terrain is beautiful, it looks rough and more real.

Instead, when I turn it on, the terrain only looks more lighty. What's wrong with my pc (or my game)?
