    Default Venezuelan spanish is the same that spanish

    Agreed, I'm Chilean and I went through the page reading everything without problems. The most difficult one is the one spoken by a minority in Europe, and even that one is quite easy.

    With Intel you got open-source hardware support in the kernel even before the chipset is available in store, so when you go pick it up in the store it is immediatly supported out-of-the-box.

    The Nvidia proprietary graphics device driver works great, except for lack of support of kernel mode setting (KMS) and XRandR. It always support the latest hardware, and releases are relatively quick to catch up with X.org ABI changes.

    With AMD it never supports the latest graphics cards and it lags behind X.org ABI changes so much that they end up holding back Linux due to distributions not shipping the latest X.org due to AMD not having a device driver out that supports it.

    GL1, AMD are you kidding me?!
    This.
    Linux drivers and OpenGL performance have been on ATI's todo list since forever. Good hardware without proper hardware support is a job half-done. That's why it's always nvidia for me. Hell, nvidia even had time to develop VDPAU years ago, which proved to be a very successful library right from the start.

    Actually OpenGL performance is quite good with fglrx EXCEPT in composited desktops. There it sucks ass. With all of them (Gnome Shell, Compiz, KWin). I mean, it's really really bad, to the point that an Atom N270 netbook with it's crappy GMA950 offers EXACTLY the same desktop experience as much more powerful Radeon HDs from AMD (namely the HD4200 which is what I have tested, both with fglrx and radeon).

    Depends on what you mean by "quite good". Afaik, their OpenGL performance lags behind Direct3D. With nvidia, they're usually on par (I get 34fps in unigine 2.5 in dx11 and 31fps in opengl mode). I'd ve happy to hear AMD has closed this gap, but I haven't seen many OpenGL tests lately and none that compared directly to DX.

    Because if AMD fix the bug today. then the fix is at the earliest in 3 month in in the driver release.

    I don't use windows so I have no way of testing that. However I found this article a few months old where OpenGL performance with Ubuntu was better than Windows. I also remember seeing some post a few months ago in the forums where a user was getting numbers similar to yours (with nVidia) with Catalyst.

    ..and you were serious! Thanks for making me spit out my coffee in laughter!

    Better hope it doesn't take them as long as it did to fix catalyst's issues with gnome-shell LOL.

    Yeah, that's why I got intel with my new laptop. Spotty performance with compiz, and totally not working with gnome-shell. My old laptop has an hd2600 with 512mb of dedicated vram. The integrated ironlake graphics on this laptop give me better performance with compiz/mutter/kwin. I don't play any games so the dedicated card was just becoming a burden anyway. So glad I no longer have to use any proprietary drivers.

    But we don't know how similar the OpenGL and the Direct3D renderers actually are in Unigine.

    Are there reasonably complex benchmarks where it was even possible to implement the same algorithms in a similar way in Direct3D and in OpenGL so that we can know we are actually benchmarking Direct3D vs OpenGL implementations in the graphics drivers?
