Major Performance Improvement Discovered For Intel's GPU Linux Driver

Posted by Soulskill on Friday November 7, 2014 @01:49AM from the striving-for-parity dept.

An anonymous reader writes: LunarG, on contract with Valve Software, discovered a critical shortcoming with the open-source Intel Linux graphics driver that was handicapping the performance. A special bit wasn't being set by the Linux driver but was by the Windows driver, which when enabled is increasing the Linux performance in many games by now ~20%+, which should allow for a much more competitive showing between Intel OpenGL performance on Windows vs. Linux. However, the patch setting this bit isn't public yet as apparently it's breaking video acceleration in certain cases.

Probably the "Official driver" bit

That's probably why it wasn't being set then.
