    It would work stright away, if it was no problem to implement right . Simply, devs still does not know why it does not work . Until someone figured out why .
    I've got every other revision of the GCN GPUs running on the OSS stack without issue, with OpenGL3.3 working, full video playback acceleration etc. Everything from the HD8210 on up to the 280. So tell me, what game with a proper port on Linux that is out today needs anythin faster then the 280? 4K doesn't work on Linux at all and lower end GPUs already handle 1920x1200 perfectly.

    Are we supposed to take something useful out of that? Because i sure can't.
    Clearly useless posts, but I'm AMD and open source drivers user and I can't argue with fact that Catalyst is crap.

    Statement like "both latest amd and nvidia cards work *now* with their blobs." aren't true and it's what I posted about above. 290 and 290X is waste of money with Catalyst on Linux because performance is unacceptable low compared to Windows driver.

    PS: And yeah I'm really confused about GPU generation naming/versioning...

    Hell. Why do every press site call 290 as "Volcanic Islands" then?

    But, Catalyst isn't a piece of OpenGL support crap?
    get a refund and buy nvidia
    Are we supposed to take something useful out of that? Because i sure can't.

    260/260x and 290/290x are both GCN 1.1 chips making them very similar. Also, Kaveri APUs are GCN 1.1.

    All the HD7xxx cards were GCN 1.0.

    As for GCN 2.0, rumor has it we'll see it in August w/ Tonga (mid-range).

    Volcanic Islands hasn't come out yet, that's the next gen.

    7790, 260, and 290 are all Sea Islands.

    The rest of the SI cards (7xxx,270,280,etc.) were all Southern Islands. I think.

    I'm not trying to attack devs there, but just agree with fact in this article: Hawaii support is broken.

    Phoronix is only website about Linux graphics so if "managers" read any it's this one.

    Multiple hardware-related websites reported that R7 260X is a rebranded 7790 with unlocked audio part (TrueAudio). Fake?

    PS: They also have mostly the same result in benchmarks too.

Give it another year, Star Citizen, Metro Complete Pack, Civilization: Beyond Earth, Witcher 3 and whatever else gets announced will provide a need for a focus on the high end GPUs sold in the hundreds of thousands as well as the low and mid range that have sold in the millions.
    Of course that is somehow priority excuse because it does not work stright away , i don't believe in that (about numbers) story at all in the matter "chip can't work" and that is because of numbers... i mean that is funny to say and even more funnier who believe at that .

    Only reason why I participate this topic it's because I want AMD to fix their driver and want to see more news on moving more resources towards proper driver. So I seen this news and it's message I can read: hey AMD, fix this! Unfortunately fanboys fail to see this and only see some "Nvidia trolls".

Blame managers not developers. As for devs, they are doing an awesome job! One year ago the only option was fglrx but now I completely switched to radeonsi and it works nicely!

    I bet the problem with this particular GPU could be a stupid typo somewhere in the code as was in a case with dpm on cayman (single line patch fixed a crash on it)...
