    [Success] Radeon RX 6800 XT - Big Sur

    Well using WEG on GPUs that have natively supported hardware encoding/decoding actually gets broken.

    Make sure you have the last kernel patch (Shannee's Fix PAT) enabled and the second to the last kernel patch (Algrey's Fix PAT) disabled. By default, Algrey's patch is enabled and Shannee's patch is disabled. Be aware that by using Shannee's patch if you are using DP/HDMI audio it will have...

    Try adding this VFCT.aml to EFI -> OC -> ACPI folder and in the config with your original VBIOS switched over.

    Not sure if that will work with the RDNA 2 GPUs since the ATY,bin_image isn’t being exposed to the OS, like it did with earlier GPUs.

    I also had a Radeon VII and its 100% worth upgrading, I went with the Sapphire Nitro+ RX 6900 XT. Now just need to sell this Radeon VII.

    I did this and supplied a PR on AMD OS X Github repo awhile back, it was revered because users can just disable which patches aren't needed on their own. The CPUID registers to identify the CPU vendor can not be renamed within a DSDT or SSDT. They are read directly from CPU itself. This is how...

    TRX40 users do not need any of the 2 Fix PAT kernel patches. There is actually quite a few kernel patches that are outlined for AMD users that TRX40 users do not need. Ryzen users on the other hand must use them. One main take away from all the testing I have done on TRX40 and regular Ryzen...

    Guess I read it wrong, my bad but you should still be able to do it with the `-mb` option. -mb <Num> <File> Modify SSID, SVID, BIOS Pin Number, & Boot Message in BIOS image of adapter <Num> to values in <filename>. Input file example...

    You shouldn't need to use a hex editor to change the device-id of the GPU. You should only need to re-flash the GPU with the option `-padevid=<ID>` in the command. Make sure to check the help command for ATIFlash. Example: AtiFlash.exe -f -pa -padevid=73bf 0 newenhancedbios.rom

    Just a FYI..... `shikigva` boot-args do not work in BigSur. https://github.com/acidanthera/WhateverGreen/blob/master/Manual/FAQ.Chart.md#drm-compatibility-on-macos-11

    DP 1.2/120+Hz is supported in macOS, all depends on your monitor EDID mainly. Like my 1080p monitor works with 144Hz but only in one of the DP ports, if I plug it into a different DP port, it doesn't give me an option on refresh rate. Play around with the ports.

    Incorrect, like for example Windows supports 4k/120Hz over HDMI while macOS does not. macOS only support 4k/60Hz over HDMI. Because the AMD drivers for Windows support HDMI 2.1, where as the macOS drivers does not support HDMI 2.1.

    Not in a bad mood at all... People just need to stop trying to compare features from different operating systems is all. Each operating system handles features of devices in different ways, where you get functionality in one operating system, doesn't mean you will get the same functionality in a...

    Why do people continuously compare what they get in Windows to macOS time after time again. They are completely different operating systems and the drivers functions in completely different ways. Its mind boggling.....

    Can you upload your entire EFI, it looks like you have somethings that shouldn't be there.
