Grid Autosport always crashes at the same place in its benchmark (just before the big hill) but I found if I disable the SB Shader optimizer (R600_DEBUG=nosb) the game runs perfectly throughout. My GPU temperature is fine (tops out at 62c on a hot day) so that does not seem to be an issue. I've dumped the shaders for both when the game crashes with SB and when it is running fine with nosb in hopes they might help (I've followed what Jürgen Scholz did at issue 93352#c7). I won't be near this computer for a few weeks now but if you let me know if there is more info you would like me to gather in the next 24 hours I'll see what I can do. FYI my system is: Ubuntu 16.04 Mesa from padoka PPA (12.1~git160603151200.a64c7cd~x~padoka0) SAPPHIRE VAPOR-X Radeon HD 5870 AMD Phenom II 955 For now I'm just attaching the shader dump from the crashed SB version. If you want them I'll upload the nosb variant as well? I've also attached the script I made for debugging the game.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
