The driver doesn't set if early z is enabled directly, since it just sets EARLY_Z_THEN_LATE_Z most of the time, and the hw should figure out if early z is possible (taking into account all state), otherwise use late z. If that's the case, then overriding the Z_ORDER to LATE_Z for the db_shader_control value might be necessary in this case. But that's just a guess, I could be completely wrong here - I've got only a very rough idea of radeonsi hw and driver...</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
