    Oh damn edit timeout. Of course I mean in 2014.

    It would be better it you think before you write. Bumblebee works with an on-demand started 2nd xserver as the Nvidia hardware is switched oft with bbswitch while not used. That's undetectable via glxinfo without preloader, but the officially supported variant has the Nvidia driver active all the time and can not save much energy while you don't run games, vsync is currently not supported as well. But the speed you can get is much higher than via Bumblebee. Btw. the xrandr code that Nvidia is using does not only work with modesetting, but with Intel and even radeon as output device as well. I used a HD 4550 and GT 630 OEM in a Q67 Intel board to check.
    What does it have to do with Steam supporting optimus or not? Evasive answers always win arguments, don't they?

    You can be sure I know how this works, but he mentioned Bumbebee and that works differently. I can configure Optimus with Kanotix Spitfire as well, but it would not work with pure Debian because of a recent xrandr fix in the xserver which would require a newer Nvidia driver than currently available in official Debian repositories or a patched xserver. Bumblebee uses optirun or primusrun which can be configured per game in Steam, just like using a "DRI_PRIME=1 %command%" override with OSS drivers. The official Nvidia way requires a restart of the xserver with different xorg.conf which is done smart in Ubuntu with a lightdm startup script.

    Also Intel have like 60+ full time employees who work on Linux graphics stack (calculations from git logs there).
    This is likely more than AMD FOSS, AMD Catalyst (Linux) and Nvidia (Linux) have together.
    For example last time I count Mesa+Radeon+HSA developers of AMD there was like 15-20 guys.

    Your point is fair, though, as far as graphics are concerned.

    If Valve could do it than OSS devs would be able to do it pretty fast as well. So we will have good OSS Vulkan.

    Take notice to many who think Intel is some sort of great supporter of Linux. Valve has far fewer resources to leverage and manage to do this work.

    I was responding to

    Although, Vulkan on Intel seems kinda pointless, will be GPU limited anyways.
    in particular.
    The point was pedantic if I understood you to be saying that Intel GPUs aren't worth the effort of supporting vulkan because of their, relatively, low ceiling performance. I was simply saying that all GPUs will be GPU limited in scenarios where the bottleneck isn't the CPU... but in a more succinct way
