           Version: 2.5
    Kernel Version: master
          Hardware: All
                OS: Linux

            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri at kernel-bugs.osdl.org

        Regression: No

I have Acer Nitro 5 with Ryzen 5 2500U and RX560X.
The dGPU is wired into iGPU (VEGA8) so we have to use PRIME.
I reported a bug earlier about tearing in games.
I have been told i have to wait for scatter gather support.
Now that its in place i tried it to my suprise tearing was still there.
Only way to get rid of it is to use TearFree which intrduces stuttering at even
60fps.

If you need anything just tell me i will be happy to provide any logs or that
sort of stuff.
