Let's see how much can Valve help in improving OpenGL performance on Linux.

    don't know if it is just conspiracy theorist in me, but that paper was contradicting it self on all fronts like he wrote it half drunk and forgot what he wrote in previous sentence. just to name a few
    - directx coders know how to code, opengl... NOT (translation, if it is a car and red it is a sports car, if it is blue it is a truck)
    - all coders more optimize directx implementation, then says valve obviously didn't (how so?)
    - claims valve coded for dx9 and then graphs show almost same results for 9 and 11
    - coders optimize for dx11 rather than 9 (leaving me wondering if everything till 11 was a pile of crap)

    but, the claim where my alarm went ballistic was this
    "If we really want better OpenGL drivers, what we need is programmers that write better OpenGL programs."
    huh????? based that they wrote their benchmarks for OpenGL.... it leads to
    - benchmarks they provide are complete crap as there are no coders that would know how to code, god forbid optimize OpenGL
    - they are sole coders on this planet that know how to use OpenGL efficiently
    - wondering as last time i checked ps3 and ps4 for example don't have DirectX and since there is no coder who'd optimize all games for those run at 70%

    and i'm no linux'be'all evangelist. if it doesn't suit somewhere, it doesn't, if directx is better, why not. why would i care? i don't use windows from personal belief and i wouldn't even if they strapped 3 hookers on my win box for the same price as OEM.

    still, reading that was triggering same bullshit alarm as reading MS published reasoning why Server 2003 over linux. and then you look at hardware they used... absolute worst from NEVER, EVER use that in linux, where winner was Raid controller which worked at best 5MB/sec in linux. was really funny looking at results they got there/ i wonder how much network traffic was. maybe, 5MB?

    You wouldn't fuck 'em becuse you dont know what to do with them =D

    If I get this correctly, you just said you 'dont care/what do I care what is used', then you used a euphemism stating you wouldn't use Windows with strap-on hookers.

    Othwerwise, I think I'm lost in translation =D Yeah, go for that. I jsut like the idea of strap-on hookers threefold.


    On an even lighter note, YAYYYY SteamOS. You can go away thinking yet another person, Michael, realises the point of this article!

    yea, i don't care and i wouldn't use win. nor osx. i stand at what i said.

    but, the fact that i wouldn't use windows never posed slightest trouble to suggest those 2 when i felt they will do the needed job best and fastest. more than few times i suggested windows server infrastructure and redirected as i knew their environment was too dependant on some strictly windows services which might pose trouble later if they were not compatible in planning.
    hell, i even code software for windows on linux and i have no hard feelings. all i do is code so cross platform i never need windows in order to be sure it will work 100%.

    what would be strange here?

    I don't get what's happening in the first two graphs. The latency graph clearly shows that Windows has much less latency on all cards, and it's not just the spikes. But then the bar chart shows Windows has lower FPS than SteamOS. That looks contradictory to me...

    Default windows has higher latency!

    did you misinterpret it?
    the y-axis says "less is better"
    and what you can see is that steamos has the lower latency comparing same cards. It is however quite hard to read because the colors overlap so much. But look again, on most points you can see that steamos is slightly lower==ahead of windows. Also the spikes are bad and they seem to be there only for windows - assuming that there are no steamos spikes exactly hiding behind the windows ones.

    Default directx?

    and yes - it was all tested in opengl 4.4, as clearly stated in the box on the first page of the benchmark. And yes, a directx comparison would be interesting!

    Oh, OK. I thought one orange was the other orange, and there not being any purple anywhere also makes ir more confusing.

    Default purple

    you can see some purple. it is the lowest color, right below the red. you should check your monitors color or zoom in a bit

    I meant at first glance. Sure, you can see the few fragments of purple at the bottom of the red line if you try, but it's not exactly obvious it's there when you look at it for the first time.

    Playing back X input is not reproducible, because games have randomness. The enemies might behave differently, and so on, causing a different graphics load.
