In latest 1.17.30.24 I noticed Huge performance drops in Fullscreen mode, I switched to previous Beta versions to make sure it is only happening in latest Beta (and It was)
This might not be the same as MCPE-121850
as I had Vsync disabled (Which was the fix to the report linked above) and also tried different settings in Nvidia control panel for Vsync.
severe performance drop can be seen only in fullscreen mode.
Steps to re-produce:
1. Create a new world on 1.17.30.24 or 1.17.30.25 with a PBR resource pack applied.
2. Turn Ray tracing on
3. make sure you are in Fullscreen mode (other settings such as VSync do not matter, I've tried playing around with these settings & didn't make a difference).
4. Start flying around in the world (fps is far more stable when not moving at all)
5. Observed results: Performance heavily drops
Expected results:
Performance should be the Same or better than Previous versions or 1.17.30.23 Beta
Other notes: just to do it in a cleaner way, you can first create a world in 1.17.30.23 Beta, play around, look at your frame rates, export world, import it in 1.17.30.24 Beta and start monitoring frame rates again, this is only to have same conditions (all in fullscreen mode)
Important Update: I noticed I can maintain 60 FPS in fullscreen mode too Only if I stand still and Do not move or run or fly anywhere.
As soon as I start flying around I notice frames dropping to lower 30s, which again isn't the case in previous betas.
I updated re-production steps

Resolving temporarily as Awaiting Response. Could you please attach the texture pack you're using to this ticket?
I doubt a normal resource pack can be the cause, but there you go mediafire
Could you please include more details about your system (RAM, CPU, GPU spec)? You can run dxdiag and copy the relevant information from there. (Win+R → dxdiag) - be sure to remove any personal information, just the PC specs would be useful.
Without the information we may not be able to reproduce the issue.

Windows 10 Latest (21H1)
Intel i7 7700k
Nvidia GeForce RTX 2070 Super
16GB DDR4 RAM
Minecraft is installed on a SATA SSD with ~40GB free space.
I also looked around more in Nvidia control panel, tried to uncap fps but no luck sadly.
I believe my specs are absolutely enough for 1080p@60fps, switched back to Previous betas/none beta before 1.17.30.24 using Minecraft Bedrock Launcher, everything is absolutely fine in all of those versions, I tried downloading Latest Beta (1.17.30.24) directly from Microsoft store today (without Bedrock launcher), same issue occurred, insane fps drops in Fullscreen mode only.
just in case, this is bedrock launcher BedrockLauncher/BedrockLauncher (github.com) which allows Win10 players to change versions easier, hence I'm able to confirm I'm facing the problem on latest beta (1.17.30.24)
If others aren't able to re-produce the issue let me know, might be something on my end, which in that case I'll have to investigate more about the cause, but it seems unlikely as it worked fine in previous versions.
Update:
I was able to fix the problem by turning "FXAA" off in Nvidia control panel, this shouldn't be an issue anymore.
