    TSMC is responsible, next year Arctic Islands and GloFo will fix the inconveniences. :lol:

    It seems that some websites are testing new R9 390X with older 15.5beta drivers and some are using new 15.15beta and 15.20beta drivers for 300 series. New drivers are responsible for some of the bigger gains seen from 300 series cards over 200 at the same clock.

    This is from a post on another forum:

    Greebo wrote:
    Someone else also mentions that they've got 10FPS extra in Witcher 3 after flashing R9 290X to 390X and installing 15.15beta driver (another way of making them work than modifying .inf).

    This must be that completely rewritten driver AMD mentioned not long ago. It would be interesting to check how many draw calls Hawaii can do with it compared to current driver. I'm expecting this aspect to be improved and closer to nVidia in DX11.

    When did AMD say they were rewriting their D3D driver? I missed this....

    It was during their PCGaming event I think. I'm sure I've heard it and not read.

    Anyway I went ahead and installed modded cat. 15.15beta on my R9 290X. It gave me 1FPS (3%) extra in Witcher 3 at the Skellige on the sea. The location is not very demanding and I had no time to go back to Novigrad or Velen to test there. Important to note is that I play at 2560x1440 so performance gains might be bigger at lower resolutions. Also the guy claiming 10FPS gain in Witcher 3 is on cat. 15.20 and he has CF!

    Still 3% is more than 15.5beta gave me 2 weeks ago :)

    EDIT: Before someone says - Pics or it didn't happen ...

    The following seems to point to significant changes:

    I should say I was sure I've read it and not heard it ...

    This is the source I gathered it from, thanks 3dilettante!

    PS. I need to test same setting in Windows 8.1 as some optimizations might be only working with newer WDDM! Please give me few minutes ...

    It turns out Windows 8.1 is no better for Witcher 3 on AMD :)

    Identical performance so nothing really to report.

    That's all I have time to test for now as it's already 1:30AM here, time to bed!

    It would also be interesting to see if there are any gains with less powerful CPUs and also whether VLIW GPUs have had any gains.

    Hopefully they are also going to rewrite their shader compiler. That would give even bigger gains.

    You mean there's more to drivers than the compiler ?! o_O

    Not a good look for AMD.

    I don't understand the glowing reviews for the 390 series, considering the enormous price difference between those and the 290 cards.
    Why would anyone buy a 390 for 350€ when the faster 290X can be had for 330€ or the similar performing 290 can be found for as little as 270€?
    And the 390X's 450€ price is nothing short of obscene. 120€ for more VRAM and a minimal boost in the clocks (so minimal that it's practically non-existent, considering how many - if not most - 290X cards were already using those clocks).

    The 390 cards are a terrible deal, compared to the 290 models.
    Same thing with the other 300 offerings. 150€ for the 370 with a 16 CU Pitcairn, while the 270X with the full 20 CU Pitcairn and higher clocks can be found for 145€.
    R360, a cut-down Bonaire with 12 CUs can be found for minimum 115€, while the 260X with the full 14CUs Bonaire and same 2GB GDDR5 costs around 110€.

    The only new SKU with somewhat increased value is the 380 over the 285 because of the increased base clocks, but even there we could already find higher-clocked 285 cards with the same 980MHz, for the same 210€.


    Perhaps the prices in the USA are drastically different, but for an European these reviews make no sense to me.
    Are they only testing the 390 series against those rare and old 290/290X units with the horrid stock coolers that no one bought?
