Major Performance Improvement Discovered For Intel's GPU Linux Driver

Posted by Soulskill on 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

      The Intel drivers for Linux are official and open source. They are actively maintained by Intel themselves. This is not like the Nvidia/Nouveau split, Intel are actually very open source friendly in this area.

    You read the article, but did you read the summary?

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

    I agree. The only thing it is missing is a good text editor.

    As a longtime user of both "My Distro" Linux and "Mine" Linux, I can honestly say that I have never noticed a performance difference between them. However, I can emphatically state that "Your Distro" Linux sucks.

    ...and you won't believe how easy it is!

    C'mon editors, it's like you missed the entire social media headline writing class.
