    Nobody can tell I guess. But I ran the AC benchmark with an RX580 4GB and at max details and 2560*1080 it achieved just 57 FPS AVG. How much will the 570 be slower...15 FPS? Not a good baseline to enjoy the next title with a lot fancier graphics.

    I'd return the 570 and wait until the Vega 56 gets cheaper - it's coming down already. If you're not AMD bound you might want to consider a 1070 TI which has become very attractive bang/buck wise.

    not really interested in max ultra settings anyway, i just want 60 fps medium settings at 1920x1080

    Hopefully not..
    Depends what Nvidia feature they use in engine..

    Lucklly there is not Nvidia Hariworks in ACC so we can cross that one out :D
    Maybe they are sponsoring and helping out with physx

    What would they do with PhysX anyway? Collisions?

    And we already know that CPU will still be the limit for AI driving physics for example, even Project Cars doesn't seem to use PhysX on GPU for anything major, all the load is on the CPU. If it's PhysX on CPU it makes no difference if it's a AMD or Nvidia GPU.

    It will run as well as the devs can make it run, given the software and hardware. Why would the devs not try to make the game run well on every PC so they can get the maximum amount of sales?

    I would think unless AMD or Nvidia had some intervention in the engine specifically then the relative performance between the two will come down more to drivers then hardware, assuming the same general hardware level for both cards. I must say that I had far less weird issues with my old R9 290 then my current 1080Ti

    I believe it was mentioned here before that the engine itself doesn’t know or care what hardware it’s running on. It just tells it to do stuff and it does things... lol

    If they have some collaboration with NVidia... could that mean dedicated driver support when the full game launches? You know, some big AAA games get a dedicated update, to improve performance on that particular game. Not even necessarily that good or acclaimed franchise, The Crew 2 got it's driver update, even when part 1 wasn't that good and... part 2 wasn't that good either.

    Project Cars 2 got this kind of update too: https://www.geforce.com/whats-new/articles/project-cars-2-total-war-warhammer-ii-game-ready-driver

    Indie games (and most games) generally don't get a dedicated driver, but have to work with what NVidia happens to release. Certainly never happened with AC1.

    Unreal Engine 4 Games are running always faster on Nv, because nvidia and epic are working more closely together.
    Check out the benchmarks.
    Same will go for ACC.

    I just hope kunos has the common sense to stay away from gameworks stuff.

    cant find the thread but stefano has already said somewhere that they wont use vendor specific technology as it divides the userbase and means multiple builds for each vendor, which makes life more difficult behind the scenes.

    I recall him stating something similar in a video interview a while back when it was brought up.

    From 28 to 35 minute mark I think it's fully discussed. And it was asked similar to the OP. So I take it that there is a serious concern for AMD graphics cards users when it comes to UE4 games.

    The new UE 4 engine is incorporating Vulkan support now. Not sure when that version will be available to developers for actual use though.

    I recall playing NFS Shift which actually used physx for tire modeling, etc. and it used x87 code. Cornering always resulted in stutter, lost of input control and lower then expected frame rates. The game was never smooth. I recall many complaining about it on EA forums back then. Fast Forward today PC 2 now used AVX.

    I never heard ACC using physx. Lets hope for the best that both Nvidia and AMD will have drivers for ACC when early access comes out.

    Yeah, thanks for confirming this, I was sure I saw the post somewhere and I searched for it for hours but didn't find anything, in the end I started to think my brain was making it up :D

    - Grab early release
    - Test
    - report back any bugs or issues
    - devs check it
    Start over with a new build is released.
    End result...hopefully a stable final release aka full game.

    The early access is really going to tell us if this is the case or not. I say wait a few more weeks and those with AMD cards will see for themselves and will tell the rest if there are issues with performance or not.

    When a dev uses middleware, in this case, UE4, it’s a reasonably safe bet to look at how well that engine supports features and hardware to get an idea of how much the game is likely to support said features and hardware. Assuming the dev fully utilizes the functionality at hand.

    That being said, devs try to be as general as possible for the widest range of support. Case in point, specific to AMD question, all consoles use AMD GPU’s, and as such middleware engines have strong support for ease of porting from PC.

    I’m sure Kunos will try to support the largest cross section of games following UE4 guilines as best as possible.
