--- Comment #47 from Loris Zinsou the-lz-himself@orange.fr 2012-08-26 08:39:26 CDT --- I have some news (wine 1.5.11, same nvidia Optimus m540): now KOTOR 2 (Wine version) crashes complaining about the same Pixel Format thing, as well as Team Fortress 2. And it seems to happen only on Optimus latops (these games launch and run fine on a non-optimus nvidia desktop).
Could any OpenGL guru (somedy who deals with the Pixel Format commits in Wine git) investigate this, at least to be sure this is a Bumblebee/VirtualGL issue, and not a bug in Wine which is triggered only on optimus laptops ?
For now, I see 3 things : 1) All these games crash because something goes wrong with the pixel format 2) This only happens on Optimus laptops 3) This only happens in Wine, Native games run fine with Bumblebee, and many other games run fine in Wine on Optimus laptops. For now I'm not sure all possibilities have been examinated.
