    This crash still exists with the 20.9.1 AMD Driver. I have a AMD Radeon RX 580.

    But I confirm the message from "CHRISTIANSCHL".
    The crash doesn't happen if the settings is set to Standard !

    Direct3D 12 don't support creating MSAA swap chains--attempts to create a swap chain with SampleDesc.Count > 1 will fail

    Still exists in 2020.1f1

    It exists on Linux (Manjaro) with Mesa drivers for Radeon RX 580 on Unity 2019.3.3f1.

    AMD Radeon RX 580
    Driver: 20.2.2

    Had same issue after updating Radeon driver.
    Crash doesn't happen if settings in Radeon Software -> Performance -> Advisors is set to Standard.
    Can reproduce crash by using Gaming or eSports settings.
