    Nice, first result of the 5700XT :)

    13 % faster than my 64 and 14 % slower than a 2060 :-(

    ****! Expected somewhat better performance! Might reconsider my August upgrade plan.

    It's a real shame...amongst all UE4 titles ACC seems to be one of the worst for Radeon. 5700 XT is better than the normal 2070 in most benchmark - it's the 5700 XT's target on the market! In ACC, the 5700 XT is 35 % slower than the 2070 :-(

    I can only encourage all AMD users again to use the report tool in the Radeon driver download section. In the following dialogs you can choose "poor performance".

    AMD is adding specific support for selected titles...maybe enough requests will make them cover ACC.

    My 5700xt is the reference design from AMD with default settings. It's nothing overclocked. I have also tested with a higher power limit (Afterburner +50), then the card runs at about 2020 MHz at 85-90 degrees Celsius:

    2019-07-19 20:37:13 - AC2-Win64-Shipping
    Frames: 4690 - Time: 60000ms - Avg: 78.167 - Min: 57 - Max: 114

    That's not a big difference compared to the standard settings.

    Are you sure the GPU even ran at 2020 MHz during the benchmark run? At such temps I'd expect it to auto-throttle.

    How about undervolting? It's a common trend for Radeon that undervolting increases clock speed (automatically) and FPS while reducing temps and power consumption.
    Unless you're CPU-bottlenecked, undervolting a Vega, for example, increases FPS by up to 10 %.

    The first result was with standard settings.
    In Wattman this means "manual" in the tuning settings.
    But there are other settings that I have just tried. "Automatic Undervolting", "Automatic Overclocking of the GPU" and "Automatic Overclocking of the Memory".

    Here again fresh measured on all settings (GPU and Memory clock, GPU Temp und Power via HWInfo):

    Standard (manual): GPU Clock average ~ 1,920 (max 1,950) Mem Clock 875, max Temp GPU 87, max Power 188 Watt
    Frames: 4661 - Time: 60000ms - Avg: 77.683 - Min: 57 - Max: 110

    Automatic Undervolting: GPU Clock Average ~ 1,970 (max 2,000) Mem Clock 875, max Temp GPU 88, max Power 188 Watt
    Frames: 4730 - Time: 60000ms - Avg: 78,833 - Min: 57 - Max: 113

    Automatic Overclocking GPU: GPU Clock Average ~ 2,015 (max 2,070) Mem Clock 875, max Temp GPU 89, max Power 220 Watt
    Frames: 4794 - Time: 60000ms - Avg: 79,900 - Min: 58 - Max: 116

    Automatic Overclock Memory: GPU Clock Average ~ 1,920 (max 1,940) Mem Clock 890 max Temp GPU 88, max Power 188 Watt
    Frames: 4670 - Time: 60000ms - Avg: 77,833 - Min: 57 - Max: 114

    Thanks for sharing. Wattman is an ok tool but has some mysterious bugs. Also, the auto tuning settings did little to nothing for me. I re-installed the driver, did NOT click accept in the Wattman, a ymore and switched back to Afterburner.

    But you can do it in Wattman if you prefer that tool. Just set the voltage control to manual and reduce each value by, say, 80 mV.

    Thanks for the results @schorni and congrats for the new system.
    Its what we about what we expected @LeDude83 your vega is the best variant out there so difference will be around 15 % for similar models .
    @Ole77 simlar by me for ACC better get rtx 2600 Super or rtx 2700 for 400usd/420 euro i personally will go for strix 2070 super

    cant edit my post so i will write another.
    When you buying new GPU you have to consider your monitor and the Freesync support. It make big diffidence
    Some Freesync monitor work with Nvidia, but some not (especially the 75hz variants).
    In this case 5700xt is better option bcs 80 fps is still respectable and you will get much better experience than 100+ fps on 60hz (bcs you can run 75hz only with freesync on those monitors)
    We dont have to forget also anti lag that works well in 60-80 fps range and eventually radeon image sharpening.
    So we dont have to write of 5700xt in all cases

    I'm pretty sure this is incorrect, if it's not compatible you won't have variable refresh but the max refresh of the monitor stays @75Hz, if it's compatible the only thing you will miss is LFC (low framerate compensation). I would still suggest to have both high refresh rate and freesync because it's buttery smooth.
  16. Berniyh

    You can always run a monitor at its max refresh rate without adaptive sync.
    LFC should work as well if the range of the display is wide enough. If you're looking for a Freesync 2 display that should be the case.
  17. Martin_Top

    If we talk about LG monitors you can do real 75hz only in freesync mode otherwise you can force 75hz with nvidia control panel but you will have 75hz with frame skiping. (they are alot of threads about this in other forums ). Im not sure if nvidia support fully and without bugs (blurring) adaptive sync on those type of displays.

    The Combination of cheap FreeSync monitors and Radeon GPUs remain s a strong selling point. I tested a very good Gainward Phantom GS 2070 in March or so as Nvidia had announced FS support. Activating adaptive sync worked well and it clearly did its job. But the Vega did the job a lot better, much smoother. Maybe the reason was this frame skipping thing Martin mentioned. I wasn't aware of that...I should have tested 60 Hz mode. But as Martin says - you want your 75 Hz FreeSync Monitor to run at proper 75 Hz with proper adaptive sync.

    @AC Support it seems like I'm unable to edit the first post in this thread. Or am I missing something?
