    not really, and since my free time is highly limited i'll just wait for it to hit mainstream.

    thanks!

    Hi,

    i'm a happy owner of an R7 260X, is there any chance of having a guide on how to switch to AMDGPU driver with my card on ubuntu 16.04?

    thanks in advance.

    They firmware images are the same between amdgpu and radeon. We just split it out differently. E.g., there are two sdma engines and each one could theoretically load different firmware, but so far they don't and there are no plans to change that. radeon just loads the same image on both engines. amdgpu uses two separate files, but the ucode there-in is identical. We just wanted to be as flexible as possible going forward.

    I don't know why I hit this problem... Last time I tried Catalyst on it, several months ago, it was working fine. Since then it's been lodged in a daily benchmarking system on the open-source drivers and doing just fine.

    Are you sure it doesn't boils down to settings ? (In the last test, resolution seemed to be 2560 x 1440, while here it's at 3840 x 2160. Or, at least, so says the graphs).
    I'd be curious too what the numbers turn out to be if the resolution were halved to 1920x1080. Would be more of a sweet spot for the R7 260X than 4K. ( Sorry, always critics around these parts...)

    Why can't anything be simple
