--- Comment #39 from Henry Kroll nospam@thenerdshow.com 2008-11-27 17:16:17 --- How many matrices for multimatrix vertex blending does your card support? See http://www.kludx.com/capability.php?capability=29 Yes, the above patch hack to return pCaps->MaxVertexBlendMatrices=0x4 works for me using NVIDIA 9600. I also tried setting it to 0x0 and got the expected old behavior (models collapsed onto the floor).
I read Stefan Dösinger's comment on this back in February: http://www.mail-archive.com/wine-devel@winehq.org/msg41911.html and posts leading up to that. Very informative!
