And now AMDGPU-PRO has dropped the proprietary OpenGL and Vulkan drivers and AMF, so the only thing you would get from it that’s different from the open stack is the OpenCL driver and maybe AMDVLK. https://www.amd.com/en/resources/support-articles/release-notes/RN-AMDGPU-UNIFIED-LINUX-25-10-1.html

No, they just include libarchive in Windows

I’ve only gotten that when I’ve mistyped the encryption password. They really should improve the handling of that.

Apparently so it does, and it says “HDMI Freesync” rather than “HDMI [2.1] VRR”. FreeSync HDMI is a completely different protocol and is supposed to work under Linux. Found a thread here, can you try cat /sys/kernel/debug/dri/0/HDMI-A-1/vrr_range and edid-decode < /sys/class/drm/card0-HDMI-A-1/edid? Though there is no solution there.

I thought that there was VRR support over HDMI even for versions below 2.1 spec.

Yes, there is FreeSync HDMI, which is supposed to be supported on Linux, and which is unrelated to HDMI 2.1 VRR. Don’t see anything about the monitor supporting that though (LG 24GS60F based on your previous post). Nor anything about HDMI 2.1 VRR, it probably only supports VRR via DisplayPort Adaptive Sync.
