    At first Resize bar was depicted only running on RX6x00 GPU and R5x00 CPU.
    It is now officially compatible with RX5x00 GPU.

    But what is it's CPU status ?
    If we have a compatible motherboard (X5x0 or some X4x0), does that mean that whatever CPU from R3x00 and R5x00 is suitable ?

    It's essentially a rhetorical question because I have a Vega 64, so, even if my R3800X is good, my GPU is not ; and will certainly never be.


    Pfiooo !That makes a big amount of "x" in my message ! :p

    ^^It works for me with a x570 board, a 3800X CPU and a 5700XT GPU.

    Getting SAM set up is a pita with continuing troubles and the average framerate benefit is not much better than zero.
    I dont see why this is worth the effort.
    I already have an extremely smooth experience, this doesnt look to give any benefit.

    You've possibly been saved a lot of hassle, its not ready for prime time and brings new problems.

    PITA? Not really?

    1) Know ahead of time you want ReBar set up
    2) If you know, then you create your Windows installation as non-CSM
    3) After Windows install, make sure you have latest BIOS
    4) Disable CSM, enable above 4G Decoding and enable ReBar from BIOS
    5) Use latest GPU drivers?

    The only "hard" part of the process is flipping 3 switches in BIOS.

    Making assumptions doesnt validate anything.
