And like 0.00000000000000001% chance it'll work on nv4x. The driver logic is just not there to handle those giant shaders. It should, however, work fine on nv50+, which has a real compiler backing it. With xf86-video-nouveau you should be getting dedicated EXA acceleration logic. I did notice a small bug in some of the pre-nv50 logic while trying to fix something else: <a href="http://cgit.freedesktop.org/nouveau/xf86-video-nouveau/commit/?id=278ad73475bd137eac8a49ec7a22406bfc2867e7">http://cgit.freedesktop.org/nouveau/xf86-video-nouveau/commit/?id=278ad73475bd137eac8a49ec7a22406bfc2867e7</a> Unlikely to fix anything for you, but thought I'd mention it.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
