I added screenshots to this post, hope this helps.

I really hope this gets fixed because 60fps might be a lot to some people, but with my good laptop that's super low.

Its possible its just running at 60 fps
Vsync might be enabled by your graphics driver (seperate from Minecraft)
Make sure to close Minecraft before saving the text file then re-open Minecraft (otherwise it might be changed by the game)

No, I have already checked my graphics driver, and I know it's not just running at 60fps because when I exit out of full screen I get 300fps, and yes, I close minecraft before I edit options.txt. The problem started after Renderdragon was introduced to Windows 10

For some reason I get 300-500fps with full screen off but with full screen on I get 60fps

Steps to Reproduce:
1. Go to options.txt
2. Disable Vsync
3. You open minecraft, but fps are still locked at 60fps

Observed Results:
Even though vsync is disabled, you only get 60fps

Expected Results:
Just like before Renderdragon was released for windows 10, after disabling Vsync, fps should be higher than 60fps

Seems to be uncapped when the game is not in fullscreen, but then it enables vsync when I put the game in fullscreen.

Jonathan5733 2021-12-19T20:44:24Z

Strangely. I'm getting the game uncapped in windowed when V-sync is on. Could be something with my device.

EDIT: The uncapped windowed mode with V-sync on only occurs on Windows 11. I have reported that as MCPE-151510

since the newest x86 builds now have renderdragon this bug should be prioritized to be fixed

Just don't play in fullscreen. For some reason when you play in full screen it reactivates the Vsync

Just tried the latest preview, and the fix only works when the game is not in fullscreen (Windows 10). With fullscreen on, it still locks my FPS to 60. And I can confirm that even with vsync turned off, I still notice a slight input delay compared to the x86 version of 1.18.12 with vsync turned off.

Mineliver 2023-08-06T14:39:03Z

The latest preview now have a vsync toggle but switching it off or on doesn't do anything. Vsync still can't be disabled.

Affects in 1.21.44 on Windows 11.

Affects 1.21.51 Using Windows 11
Even after using Nvidia Panel to disable it, it still doesn't turn off

I have this issue on my laptop which has an integrated gpu and an rtx 3050 TI. However, not on my older PC which just has an nvidia rtx 2060 super. My gut is saying it is to do with the the windows compositor / DWM

Edit: Optimus laptop, Fps is unlocked with windowed not fullscreen.

To People experiencing this issue when in full-screen only:
Your issue is likely fixable by disabling windows full-screen optimizations
To disable full-screen optimizations in Windows:

Locate your Minecraft bedrock exe (Usually at — `C:\Program Files\WindowsApps\Microsoft.MinecraftUWP_[...]\Minecraft.Windows.exe`)

Right click on it
Go to properties
Head to the compatibility tab
Check "Disable full screen optimizations"
Press Apply

And you're done!

Hi!
For this moment the ticket has been closed as Awaiting Response.

Is this issue still present on the latest version of Minecraft?

The ticket will automatically reopen once you reply. Thank you!

Lisa Su 2025-07-01T22:49:08Z

Yes, still present.

Go to AppData\Local\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\minecraftpe
Open options.txt
Change the gfx_vsync value from 1 to 0
Save the changes
Open Minecraft
Notice FPS is still capped at monitor refresh rate

This bug is caused by the Render Dragon engine.
