I can also confirm that I am having the same issues on Bedrock Edition PC. Running a Windows 11 5090 build and definitely not getting the same fluid FPS that I got before the 1.21.120 update.
Before the update, I was able to get a stable 165fps (capped at my monitor refresh rate) in all circumstances including chunk loading at the recommended render distance on fancy graphics at 50 chunks. I have turned off V-Sync in the game directory files as well as turned off improved input response and I still have not had any improvements from the 30-45fps stuttering when chunks are rendered and being loaded.
It looks like this issue is being tracked under multiple bug reports (MCPE-232560, MCPE-230304 and MCPE-230304) so in order for the Mojang team to investigate, it may be useful to collate them all under one? I will defer that up to you though 🙂
I hope it can get fixed because it honestly has put me off from playing the game at all since that update launched, getting jagged drops and cutting out is really affecting playability for me!
