    I understand your situation. I have gtx260sp216 card with 1792 megs of gddr3, of course it is LARGE card, but very powerful (less in era of 460/560+ but still its useable only with blob, and fermi support is even more damaged). So you have this card, payed for it and you expect it to perform. 5870 with gddr5, wee, yes - MONSTER.
    You insert the card and heh... Yes.
    So you stand there, between the unfree decision - opensource and borked, or blob and working investment.
    And if even your blob driver is flawed(like it was in 4670 era, several years ago), you want to throw the card in trash...

    Still radeon has most stakes of becoming somehow usable open AND performing driver. Its these 5 developers vs 2,000 that ultimately decide. Official AMD keeps telling me: a boat with least interest will get least amount of purchases, and I keep telling them : a boat with most developer attention will get most interest and most amount of purchases.

    I think their whole strategy is to attract new programmers and somehow get part of nvidia-only performance gpu cake in linux by dream a of open driver. Well, at least they fixed the closed driver so you can use the card to some degree and keep it; and some talented people(students) appreciate open driver and work on it... doing their job, fixing their own boat.

    I think the root of the problem lies within secret partnerships - ie they are not interested in selling their cards for use within linux. But not much of the concurrence here, nvidia is actually becoming crappier and crappier in linux support.
    hey the problem is the r600-hd6970 is a ati architectur not designet to be open.

    the r600 is just a testrun for the hd8000 generation of cards.

    because the new architecture are easier to handle and the opensource amd team do have access from the start on and they build a OS driver from the start on.

    meybe you just need to wait and in 2012 you buy an hd8000 and your opensource dream come true.

          r600g is in solid enough shape now that the lack of an optimizing shader compiler is beginning to hurt.

            your result isn't bad i got 3fps on an hd4770...

            your card is 4 time faster with the same driver...

              I'm having trouble accessing your site for some days now. Works via a proxy though.

                Uhm... where do you live? Maybe it's a problem with my load balancing implementation, can you try with http://diego.linuxsystems.it/ which doesn't have any kind of load bal? It's htpassword protected, so you should just see the login.
                Also, can you resolve the name? 'host linuxsystems.it' or 'dig +short linuxsystems.it'
                Thank you for reporting.

                Edit:
                My entire network has an interconnected and centralized banning system, if your ip does something wrong in a server you will be banned from my entire network. I have disabled it now, but it may have been the problem...

                    i run the same test with the same pc but i chance the card to an hd5670... also 3fps.. same result as hd4770-

                      Anyway even 13 fps is nothing! With an OpenGL 2.1 rendering and a 1024*768 resolution it should be able to do more than 100 fps with proprietary drivers, so it's ten times slower, probably even more.
                      Fortunately mesa does not still support OpenGL 4.1, otherwise it will be a slideshow

                        Do you have a link to show that? In http://www.phoronix.com/scan.php?pag...e_heaven&num=2 even the best card, 4890 with the blob, did not break 80fps at 1024x768.

                        Would the 3.x vs 2.1 codepath really have that much impact?

                          Ok. 100 fps.
                          - Consider the rendering is better than OpenGL 2.1.
                          - Consider it is 1280x1024 instead of 1024x768
                          - Consider it has 16x Anisotropic filtering while mesa doesn't support it
                          - Consider it has 4xAA while mesa doesn't support anti aliasing.
                          - Consider the final FPS score is lower than a screenshot because sometimes there are big fps drop.

                          I was wrong, mesa is 30 times slower at least.

                            4890 is garbage heatgun. It was an attempt to fight against gtx280/285 until evergreen showed up and it was partially successful - 5870, given optimized driver and application (the way that vliw5 engine is effíciently utilized) should outperform 4890 at least by factor 2.5

                            But of course, opensource driver lacks features and there is no optimization, hence this results. Still, you have a card from manufacturer that pays opensource development, which is very good.

                              Hey, mesa is opensource! All the drawbacks you listed require huge crew of driver developers with access to hardware. Damn, 1 year ago I had to disable noveau, to use nvidia driver, because noveau and its kms simply caused kernel panic on my gf parents machine with 8300 igp.
                              What AMD could do, is put many many more people behind opensource driver - and associate them the way they associate their closed source development with card sells. They refuse so far.

                              By the way, that phenom II of yours is big bottleneck.

                                I don't think there is a 2.1 vs 3.x codepath difference. It requires at least some GL 3 features, which Mesa has implemented, so I doubt they'd go to the trouble of creating alternative paths for other stuff. Maybe someone can point to a specific extension that Mesa is still lacking - the tesselation in 4.0 and AA are the main things I know of that aren't implemented yet, and that screenshot also shows tesselation off in the proprietary driver test.

                                Edit: I suppose they're probably using some geometry shaders as well. Forgot about that.
