    No. Catalyst was not even benchmarked in this comparison. Besides, all the "average user" requires is 60fps at 1920x1080, which is achievable with the open source drivers according to benchmarks published previously on Phoronix. (According to Steam's hardware survey, 96% of gamers are gaming at 1920x1080 or lower)
    I am not an "average user". I want the same or at least comparable performance with the same settings as the Catalyst driver uses, I don't buy expensive hardware to get sub-par performance. If in a game in 1920x1080 with all settings to maximum the Catalyst driver has room to enable visual enhancements like MSAA and AF then the radeon driver should give a similar performance with the same visual quality. From what I get from comments on this forum at this point it is not even possible to enable/disable MSAA, it is kind of an automatic function. If that is wrong please correct me.

    Having said that, all in all I am confident that we will get there in the not so far future, the radeon developers are doing a tremendous job.

      So the real question is:

      Has the HD 6670 the same problems the HD 6570 has or not?

      Thanks for the answer.

        Personally,

        I never expect to run anything but Catalyst for 3D until AMD itself open sources the entire stack and support for FreeBSD, Linux, etc, whilst focusing on n-tier selling of service development for the likes of Adobe, Apple, Oracle, NSA, CIA, DoE, etc within their HSA initiative.

        As one astute poster mentioned about large amounts of resources [relative to the present value of the company: Only Apple could dwarf Intel on R&D and beat them to the punch] already being leveraged, more will ramp up with the expansion of sales soon to be realized over the next several years.

        Anyone complaining about their lack of effort is most likely the same person who wishes to pay zero taxes for services.

        You want to help, one has lots of tools to debug and help narrow suspect areas of development that can expedite quicker release cycles.

          I am not sure what is wrong with Michael's Radeon HD 6570, I don't believe this is a problem that applies to all of these GPUs. Must be something specific to the card manufacturer. A XFX Radeon HD 6670 works just fine here in terms of performance, and should be noticeably (20%) faster than the 6570.

            This review reminds me why I still use nVidia with blob drivers.

            Good work on AMD's behalf though, they're really pushing forwards with their drivers. I think AMD could fix this driver cycle issue by making the hardware and firmware more complex and making drivers more simple. I realise in time, this might come true, but for now this is just a pipe dream.

              kernel 3.11 + dpm by default is not fast for games in my experience, There is needed to force the performance level to the highest level via sysfs to get it working properly

                Exact same level as will never happen. Catalyst has like PER CARD optimizations that would NEVER EVER EVER be accepted in an open source project like Mesa (or the kernel) it creates automatic spaghetti code.

                About MSAA you can modify it, its an environment variable.

                  This is why I said "at least comparable". If we get to 90% I am happy about that.

                  Only partially true: http://phoronix.com/forums/showthrea...817#post353817

                    So, opensource driver never will be as good as the privative one? so, technically is not possible? Thats sad to heard, I was expecting that day.

                    But, in my case (ati hd4200 + mesa 9.2 develop..... + dpm thing + r600 shaders optimization) steam games like team fortress 2 and portal seems to run equal (or maybe faster) than in windows using the free driver, seems than the theory is different than the practice in what I have tested.

                      yes, as stated and shown on the very first page
                      Cool, thanks for the info!
