Ever since the release of version 1.16.0+, I have been experiencing a lot of issues with performance on my laptop. My specs are: 6 core, 12 thread intel i7 8750h @3.7-3.9ghz when charged, 32gb ram @2667mhz, and a geforce 1050ti. My CPU cache has jumped up in usage, by quite a significant factor. My laptop runs extremely hot and the fans always kick into max speed.
Overall performance is still much worse, as noted by a myriad of other performance related bug reports spanning since 1.16.100 betas and into 1.16.200. This CPU issue seems to be related to vsync being turned on. However, capping the FPS seems to be exponentially less strenuous on my cpu, but of course that brings severe input lag (see MCPE-98861). Simply telling players to cap their framerate is not the proper solution...Minecraft Bedrock was inadvertently advertised as the version that performs better due to the compiled language and being able to run on lower-specced devices, however that no longer seems to be the case.
----------------------------------------------------------------------------------
RENDER DRAGON BETA: The new render dragon engine brought back in 1.16.100.59 is worse ** for performance. As a consequence of the game auto-detecting the minimum amount of chunks the player is allowed to generate, I am forced to render no more than 32 chunks. The result is a constant 100% cpu usage when walking around generating chunks, 60-70% usage when idle, lower FPS, and a strange side effect also being that my GPU is hardly being used. This may be what is causing the issue, but I'm not sure. See 1.16.100.59_render_dragon image below.
----------------------------------------------------------------------------------
Below, I attached some images to compare how the game performs in each version. I tested version 1.14.1 (which runs good) and 1.16.20 and 1.16.40 (which runs very poorly in terms of CPU usage), respectively. *note, I am using no resource/behavior packs in these tests.
In the image "1.14_generating_chunks-1", my cpu usage is at 39% when generating chunks at a 16 chunk render distance and 50 particle render distance, and no anti-aliasing.
In the image "1.16_generating_chunks", my cpu usage is at 86% when generating chunks at a 16 chunk render distance and 50 particle render distance, and no anti-aliasing. That is a massive dip in performance. Chunk loading is very slow. My cpu L3 cache is 9mb.
The effects of this noticeable dip in performance can even be seen in instances as simple as the main menu.
See the screenshot "1.14_idle_in_menu.png", my cpu usage is at only 19.2% when idle in the main menu. My fans are not even audible.
Now see the screenshot "1.16_idle_in_menu.png", my cpu usage is over double, at 42.2%. My fans kick in on the menu. Not to mention the game in just the menu is using 73.4% of my GPU.
EDIT: I attached a screenshot (called "cpu_temperatures") of cpu temperature readings for each core, 1-6. Core 1 is first, core 6 is last, read them left to right. 87 C is absurd. I took this screenshot when I was idle in my own world with 16 chunk render distance. 87 C is ridiculous for a game as simple as minecraft, without any shaders or extremely high settings.
I used to be able to turn my render distance up much higher in previous versions, but with every successive update, performance has only gotten exponentially worse.
Overall, resources dont seem to be used effectively in this game anymore, and it mainly seems to be attributed to render dragon, and yet Mojang insists that all devices should have it. CPU usage can be way too high, but the cores are not yielding better performance.

I'm idling at c29% what kind of specs are you talking about on your system. RAM, cpu cores, gpu (integrated?) avg 26% in the menus
i have 8GB Ram, quad core (AMD), integrated dual GPU (ancient)
I went into detail with what my specs are and compared it to a previous version. I do not at all think this is an issue with my computer given by the fact that I showed 1.14.1 runs just fine for me.
I have been having the exact same problem, I though it had to do with the resource pack am was using, but it was working fine in pervious versions, and even without it on I am still having upwards of 70% CPU usage with 80 chunk render distance.

even the simple thing of moving caused a lag spike for me.

I was about to say considering the render distance, 70% is not all that bad. But then I remembered that the L3 cache on a 3800x is 32mb. Still seems pretty high.
Reminder that this is a bug tracker, not a discussion site. Comments that do not add information about the reported bug are subject to removal.
In particular, this report pre-dates render dragon and is distinct from the issue of low FPS with RTX cards, which is tracked at MCPE-111547.
I have already posted this in another issue but I thought it would be some useful information. Take a look at these interesting screenshots. My hardware is an RTX 3060 GPU and an AMD Ryzen 7 5800H CPU. I'm running on Windows 11 OS (Happens on Windows 10 too). Minecraft bedrock uses way too much of my CPU (around 80%) but it only uses 1-2% of my GPU (hilarious). My ram is also being used more than it should be. The weird part is, is that sometimes it's the opposite, the GPU is used more and the CPU used less. All of this causes terrible latency, fps, render distance availability, etc.
Take note that these tests were run with a render distance of 76 to get the most accurate results.

Yep, It's a issue on my computer too. I reported it on MCPE-163184. My game had very high CPU Usage and it was using the Integrated graphics instead of the dedicated GPU. There was high IGpu Usage as well.
For a myriad of reasons, I've been playing Bedrock Edition almost exclusively on 1.14.1. This is one of said reasons. 1.14 runs effortlessly on my relatively low end laptop, but as soon as I open any version of 1.16, especially 1.16.2, CPU usage spikes into the high 90s and my fan sounds like a helicopter. This is one of the things pushing me personally away from this version of the game. Would love to see this worked on.
