    It's all good, you replied anyway

    As for sisched, I've never tried it, I was about to once but then read Marek saying it wasn't useful anymore to globally enable it, better to autoselect it with driconf as needed, and never tried.

    Shouldn't optimizations in radeons benefit most supported cards? I assumed since it was a common driver that most things would apply, unlike with lower level stuff.

    Thanks!

    By the time I tested, the stock 4.11 kernel hadnt included new enough amdgpu driver to support SI flawless. Thats why I tested with staging kernel. But youre right, that makes comparison indeed a little bit off.

    PS: The performance per buck may be worse, especially for the RX 570, RX 580 and Vega. Miners bought a lot of these cards so they're much more expensive and price stable as they should. I mean it's good for AMD. They can earn a lot of money. But it's not good for Gamers. :'/

    95 % of the games of my library run butter smooth on AMD and don't have more bugs then with nVidia. A few might need workarounds and for a few there's work being done to make them work.


    I'll personally wait for the next gen 7 mm AMD graphic cards to be released. There's no sense in buying a new card without a die shrink: No performance improvements, no energy saving.

    No one comments on the fact, that's this resolution is kind of unfair for the HD 7950.

    Micheal, did you make sure there's no overflow in the HD 7950 VRAM? I'm pretty sure the HD 7950 would look much better on Full HD. I'm not sure if there'll be more performance gains then or if the improvements will be on the same relative distance they're now.

    Given those exciting test results, i'm considering AMD to be my next card, but still i wonder:
    * how's the performance per buck compared to nvidia proprietary driver?
    * Do games have problem running on AMD?

    There is even more to expect with sisched, but I heard you need latest llvm.
    My guess is, that theres not much in the tank for SI cards in mesa. There are simply not enough devs. Their bug management is miserable. Every new optimization leads to a small bug somewhere, so they likely want to avoid that and improve current gens.
    Which doesnt mean you cant expect Performance improvements, but they are likely to expect in the kernel and llvm.

    If not, that'd mean nothing major for SI anymore and maybe time to stop using git and move back to stable after all these years.

    I think it pretty good for gaming but we need something equal to radeon chill in linux to get good performance/watt.

    How many years have passed since Fury was launched? People are complaining about Vega launch perf, but I remember when Fury was launched and RadeonSI wasn't that great as it is today, so I hope that it doesn't take this long to Vega shine
    The Fury did definitely take a while to mature. Some reviewers have revisited Vega and there does seem to be some improvements to it already. As I've said before, Vega is a good GPU, just not really that great for gaming.
