SOLVED: Trancoding performance suddenly poor

[yellowjacket_ur]

UPDATE: I was able to fix the issue by first changing the Linux kernel to 6.6.7 using a guide that others used to get Arc GPUs working. That didn't work using the Unraid 7 beta, so I downgraded by Unraid version to 6.12.10 (which doesn't have an Arc-compatible kernel).

Now I'm able to transcode my movies at more than 80 fps (see screenshot from movie: Alien). I didn't do anything else apart from what I described and now it's working I certainly won't be touching it!

Thank you for the assistance and hopefully this can help someone in the future.
