The GPU lockup and crash happens in Bioshock Infinite, right after the intro logos and before reaching the title screen. It is not random, there's no way to start the game at all without touching Mesa configuration. However, launching with R600_DEBUG=nosb makes the game start up perfectly. Everything works, no visual glitches either, only performance is lower than expected, possibly because of the lack of shader optimization. I can do an apitrace if needed, but can't replay and analyze it, as apitrace can't replay on forced OpenGL context. (BARTS only exposes 3.3, overriding is required to start the game.)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
