PC screen skipping FPS but fps monitor in cmd shows 58-60 fps consistent

Environment

OS: [Windows10] scrcpy version: [2.5] installation method: [e.g. manual build] device model: Poco F6/Redmi Turbo 3 Android version: [14]

Describe the bug Hi. Just bought a new phone, the Poco F6/ Redmi Turbo 3, which has SD 8s Gen 3. I tried casting my games using scrcpy 2.5 but experienced frame skipping in my PC screen. Before buying this phone, I use Samsung A52s which runs smoothly with scrcpy 2.0. I tried everything, even lowering bitrate and resolution but still, output is not as smooth as my Samsung A52s which is kind of odd because SD 8s Gen 3's supposed to be more capable than my previous phone.

Is this due to the chipset being new or poco/redmi phones are not capable of smooth casting in scrcpy? Or maybe I'm doing something wrong with my settings.

Please help. Thanks

If you record (scrcpy --record=file.mp4), is the resulting file "smooth"?

I tried recording and it's smoother than what I see on scrcpy screencast, finally!!!! I'm having hopes again now :') If you don't mind, what could be the problem and solution for this?

Is it smoother if you add buffering (at the cost of latency)?

scrcpy --display-buffer=50

I tried adding display and audio buffer by 75ms and it's buttery smooth now! I also tried applying v4l2 buffer but it seems to not run (I'm also not familiar what is this for). Thank you so much!!

Ok, so the source of the non-smoothness was encoder/network/decoder jitter. Do you use scrcpy over USB or wifi?

was using it through USB
