I see, I understand why the video engine usage is low.
I moved libgstva.so and disabled useX86Drm, but it seems vaapi is still being used. I've attached the log.
The display is just a regular FullHD 60Hz monitor. Thank you.

Yes, because your GStreamer has alternative VAAPI codecs. Please also move file sudo mv /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstvaapi.so /home/viseme and check how the projection behaves with no VAAPI codecs.

Was 60Hz correctly detected by the system (e. g. in Display settings)? Is there any scaling active?

The projection is now smooth after disabling VA-API (by removing libgstva.so and libgstvaapi.so).
　Video Engine: 0% usage.
　Render/3D Engine: Increased to ~60%.
　GPU Clock: Jumped from 200MHz to 715MHz.
It appears that on Geminilake, the light VA-API workload was keeping the GPU in a low-power state (RC6), causing the delay. Forcing the Render engine has effectively "woken up" the GPU frequency.
On the other hand, I am trying to increase the GPU clock speed with vaapi, but it is not working. I disabled C-State in the WYSE5070 BIOS, changed powercontrol to on and added kernel options.

Any improvement in boot time, interfacing speed with x86 system? I'm thinking of getting Lattepanda IOTA for Hudiy which has higher speed than Pi5.
