Intel N5000/QSV Performance, can I improve it?

[Breakintr]

Ok, I've enabled low-power h.264 and I'm not sure if it made a difference. Checking intel_gpu_top closely, I see this request/actual info:

Code:

root@proxmox:/# intel_gpu_top -J | more

Does this mean GPU is being throttled? Need to find a fan and point to the tiny cube to see if it improves
