    Phoronix: Intel's Sandy Bridge Driver Is Nearly Ready

    Intel began working towards Sandy Bridge support (the Intel HD graphics found on their next-generation CPUs to be launched next month) since this past February and in the months since and it's now their open-source Linux drivers are nearly ready for the first early-adopters of these soon-to-be-released Intel Core i5/i7 processors...

    That's good, informer when i got my Intel G33 board i had to wait over 1 month for initial Linux support. Btw. you could buy the board before official release just like now with some P/H/Q67 boards.

      Is there a word on proper H.264 video acceleration playback?

        I would also like to know this (SB having a dedicated video accelerator).

          I'm not sure whether VA API support for Sandy Bridge is already working but at least Haihao Xiang seems to be working on it.

          See libva git commit log for Sandy Bridge and especially H.264 decoding on Sandybridge

            Obviously, there is. Take a look here.

                MPEG-2 VLD and H.264 VLD decoding are both supported now on Sandy Bridge. VC-1 decoding and H.264 encoding will come next.

                  Did you test it yourself yet?

                    If they finish complete 3D and video-decode support AND the chip+foss code will do more than 100 fps on IDTech3, I will buy intel-only system.

                      You don't own a full hd tft? 100fps at 320x240 would be funny however

                        Considering 2 fps on Mesa Software Rasterizer, 100 fps ain't bad.

                        I currently get ~60 fps fullhd(regardless of quality settings) on openarena using 4770, where I got ~160 fps via proprietary (and buggy) fglrx from almost triple weaker 4670. So, current opensource driver is delivering only 1/5 of possible performance and only a subset of hw features. The devs are heroic though, the company not so. But it could be way worser (as in nvidia).

                          Thats completely enough because only in benchmark the game is not limited to 60 fps.

                            I have several problems with it.
                            1) The performance per watt is bad. ok, 220 fps from 300 possible would be ok; but not 1/5 of actual performance.
                            2) 60 fps is not enough for fps shooter, 85 and up.
                            3) The framerate quickly goes down if more than one player appears close on the screen.

                            I have once used 9800gt green with proprietary running one "space" kind map in QA, 16 ai players, rocket match(lots of explosions), fullhd, maxed out and spectating from the side - 120 fps.

                            Very comparable in performance 4770 runs same at 5 fps best.

                              tearfree gaming on the most tfts means 60fps is forced.

                              ok yes 85fps brings more heatshots but you got ugly graphic by tearing.
