    Heaven, Sanctuary, Warsow and Furmark. The rest appear to be either totally or partially CPU-limited.

    You can see Xonotic moving from totally CPU-limited to partially CPU-limited as the effects level is raised.

    Read it as: we don't see what happened with llvm in last 3 months here
    You can test mesa + llvm 3.6 using my ppa. I keep it in sync with both llvm git, mesa git and oibaf ppa so its very stable (as stable as git can be) and fully functional.

    The only thing i didnt add to it is beignet because its not compiling with llvm 3.6 (i sent bug reports upstream to beignet devs).

    some stuff that llvm 3.6 has over 3.5,

    borderlands 2 works with dynamic lightning enabled, some titles are faster and/or more stable and is has improvements to clover.

    test it out:

    Hi, this is the UNSTABLE, built from git padoka ppa. if you are looking for the STABLE padoka PPA, go here: https://launchpad.net/~paulo-miguel-dias/+archive/ubuntu/pkppa/ If you like/use this PPA and think i deserve a cup of coffee, do a Paypal donation: https://www.paypal.me/padoka I don't have the time to support multiple ubuntu versions, so i only provide support for the LTS and the latest. if you need support for older versions, use oibaf repo instead (URL below). oibaf ppa for refer...


    enjoy!

    Compared to 6 months ago I can play almost any game without this issue.
    So far the only game I found with this issue is NWN:O (using Wine), unplayable.

    So I'd say it's better, but not fixed.

    The 290 seems ~40% faster than the next fastest card (7950) on all the non-CPU-limited tests, which is what you should expect from the HW complement. What am I missing ?

    Some of these benchmarks might not be fit any more and limited by CPU indeed, but in general it still looks like it does not perform much better.

    The kernel actually doesn't do very much.
    Performance is mainly determined by mesa.

    ANother click-baiting article
    I don't know what's your problem. Just don't read it if you think it's not worth and don't insult people who put effort into this. I liked the read, so thank you Michael.

    If we compare let say last 6 months or better what we have this time last year... yeah many, many issues are fixed Still not complitely without issues, but of course it is better then ever

    It's ~40% faster on GPU-limited benchmarks, which roughly matches the difference in shader hardware, so that seems about right.

    The slowest card tested is ~HD4870 class and average is more like ~2x that, so it's not unexpected that the less demanding apps are going to be CPU-limited.

    Yeah, I just bought a R9 290 yesterday and am waiting for it to arrive. Even though the results for it are disappointing, it should still handle everything I want it to and it will only improve. The 290 and 290X are a different architecture than the rest of the GPUs, and the 285 is different from everything else too. So I figure it'll take a while for those to improve. The 290 itself has dramatically improved over the past year, and even though it is far behind what it should be, it's still got some leverage over many other GPUs.
