Mesa demos, quake3, freespace2 and some other stuff. > The WARP is swapped because the 2nd warp is designed for dual texturing. I got the impression from the docs that both WARPs are used regardless of texturing mode. And with strips and fans the WARPs aren't swapped. But then again I can't be sure what's really going on under the hood since the full docs aren't available... > > - I changed the dualtex fan WACCEPTSEQ value to the one used in the WARP > > DDK.

This might be reverting the fix to the infamous G400 q3 lockup. Be sure > to play many hours of quake with this test before considering it right.

Is it mentioned in cvs logs somewhere? I tried to look at the mga-0-0-1-branch logs but It seems that most of these changes to the WARP DDK values were done in utah-glx... I'm pretty sure that the WVRTXSZ values are wrong in the DDK since they would use a lot of reserved bits... -- Ville Syrjälä [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ ------------------------------------------------------- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.
