Remember the anti-aliasing issue that didn't receive an answer for two years? When there was finally an answer to that, it was simply "It cannot be fixed, blame your drivers (and our inability to upgrade to a better API)".
Well that is true. But it's true. =]
Even now, Mr Indiepath had played around with antialiasing in the dx module of Max and people are getting similar results - it just doesn't work properly in DX7 anymore. That's hardly BRL's fault.
Whereas texture compression is still working fine afaik.
