It looks like the original define was a bit off, although obviously this is not the correct one either. Someone with an actual nv4x card and better understanding of OpenGL than me should take a look and reverse-engineer the (remaining) format(s) > Weird... > > If you think it could be useful I can try to extract the code into a small > compilable test case... That's always a good idea :)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
