      Thx, interesting data, intel is the only one whose open drivers performs pretty decent, taking into account hardware limitations, noveau and r600g perform horrible.

        Intel has done well. My current HTPC is a 4500 and has worked well enough for ages thanks to Intel (hardware video decoding not withstanding).

        The gallium drivers are still new, give em time and they'll reflect the true power of the hardware.

          What I'd like to know is if all these new performance improvements will be able to be ported to Gallium3d if/when Intel makes the switch, or if they will only work with classic mesa3d.

            They are staying with classic right now. It sux, but it gives results. I hope they realize Gallium3D power and make the switch. As I am new to Intel universe, here is a question: Does it support s3tc?

              I know older graphics are not really supported anymore, but how does this changes affect older graphics?, did anyone compare it with PTS?
              I'd love a bit more performance out of my 945GME but I know it's difficult.
              Anyone knoes if only the codepaths of sandy bridge are updated?, can this be "ported" to older hardware?

                For us novices who opt to ignore your warning, are there any guides for doing it anyway? Would you recommend the xorg-edgers PPA?

                  I know, hence the "if." My "what if" question about whether they could port these optimizations to gallium3d "if" or when they switch still remains.

                    I'm going to speculate the reason Linux driver performance is now so close to Windows is because Windows driver doesn't expose full potential. The latest graphics driver for Windows, 2361 claims up to 43% benefit in the games tested: http://downloadmirror.intel.com/2003...se%20notes.pdf

                    Someone also benched it and verified the results, although the gains are lower, its still there: http://communities.intel.com/message/124739

                    Here's what the release note claims: "Hardware Transform and Lighting support in OpenGL added. Increases performance in certain
                    OpenGL applications."

                    That sounds similar to the Linux patch for enabling 60 VS threads, doesn't it?

                      I just got a new sandy bridge laptop, can't wait for this kernel The performance of these integrated graphics is already seem faster than my dedicated ati card was in linux.

                        What was your dedicated ati card? Can you be more specific about the performance?

                        I know there was a joke somewhere but I am seriously wondering about Intel's graphics support w/ Sandybridge especially when it concerns laptops.

                        The integrated Intel gpu in say i3-2410? How is the support?

                          I was actually wrong that my laptop was a sandy bridge, mine is one gen before that (Arrandale) The processor is an i5 460m

                          And support has been excellent. My old card was a 512mb hd2600. Felt like garbage in linux compared to this. I also have vaapi working perfectly with VLC player without having to do any dicking around, I haven't had a problem with the graphics yet.

                          I'm running gnome 3 on it and its super responsive and great for web browsing/video. Scrolling was total garbage on the ati card with any compositing enabled, with the intel card I can use smooth scrolling in firefox/opera/chrome with no issues, just as smooth as windows.

                            Something is very wrong

                            Ok, something in my system should be wrong.

                            I have seen reports from phoronix on i3-2100 with 2.6.39 openarena 800x600 tests at 180fps.

                            My system can only run 110fps with mesa from git.

                            What am I doing wrong?

                              Found my problem: MTRR.

                              Compiled kernel with CONFIG_MTRR_SANITIZER_ENABLE_DEFAULT=1 and voilá, got 217fps.

                                Hi, I am using linux 2.6.38 from kernel ppa on Ubuntu 10.10. will I get performance boost with MTRR enabled. my graphics is Intel GMA 4500. if I will how to enable MTRR.

                                Thank you
