--- Comment #17 from Loris Zinsou the-lz-himself@orange.fr 2012-05-08 05:30:09 CDT --- I would be glad to help testing new wine builds (If I can get it to compile on Ubuntu 12.04 64bit). As you may already know, since my only computer is laptop with nvidia optimus, I always encountered bugs with OpenGL apps in wine, but Direct3D ones run fine. And most OpenGL 32 or 64 native apps run fine too.
People assumed that something was wrong with virtualGL (the piece of software behind bumblebee, which enables optimus cards on linux), because at this time that was the only configuration that triggered bugs (setPixelFormat bug in OpenGL apps, OpenGL extensions detection failing...) but now it seems everybody has these kind of errors.
