I have seen a few people having issues getting encoding/decoding to work
using Intel 600 series motherboards and AMD RX6400/6500XT GPUs. After
a bit of digging I found a solution. Being able to use the intel iGPU for
encoding/decoding makes 8k video playback a lot smoother and less CPU

Make sure you have an intel CPU with an iGPU, any intel CPU ending in the
suffix "F" or "KF" does NOT have an iGPU. Also, this was tested with a 600
series motherboard (LGA 1700).


Enter your UEFI and navigate to:
Advanced -> Chipset Configuration

Set "Primary Graphics Adapter" to "Onboard"

Save and exit.


Connect your display to a display output on your motherboard's rear IO (not
the GPU)


Reboot the system and test 8K 60fps playback:

Make sure to select "4320p60".

Now you should be able to view smooth 8k 60fps footage without high CPU usage
and with no performance hit. Gaming will still default to your dedicated GPU so
you won't lose any performance there either. There is also the added advantage
of power savings using the iGPU for general desktop tasks etc.
