Hello, i have played minecraft for many years on xbox and pc, a little ago i have been back into the game. but while in a realm with my friends i was disconnected and when i loaded the game back in it was unplayable, i mean 1 frame per minute it was horrible, so i ended upm logging off for the night after attempting uninstalling the game restarting and re-downloading it and nothing was working. so after playing different games and all worked fine, one week later i logged back into minecraft, and it was fixed i had no problem, played for a couple of hours and then took a break(about 30 min) came back to the most unplayable game. and it only is on minecraft. please help.

Wyattyos 15 Reputation points2025-10-31T05:13:04.7066667+00:00 I am having the same exact issue. I try to play NOW after an update that happened yesterday and now Minecraft Bedrock Edition is sucking all of my memory/ram away causing my PC to lag. Note: I have 16GB ram, a I7 14th Gen and a NVIDIA 4060 so i shouldnt have any issues whatsoever.

AttackHeli 10 Reputation points2025-10-31T05:52:07.2566667+00:00 I too am facing the same issue. My realm was not working for me and a few friends, but we updated our games finally. Once we were able to get into the server, my game lags BIG time. I shouldn't be having issues; I wasn't literally the day before.

Rick278 10 Reputation points2025-10-31T18:42:25.91+00:00 Same issue here. My son went playing today for 10 minutes without facing issues. Suddenly the game got closed and pushed an update that makes the game practically unplayable. Only lagging also at the menu. (no issues with other games)

Simone Rocchetti 90 Reputation points2025-11-01T18:28:56.94+00:00 Same here… the perceived lag seems to be caused by abnormal RAM usage while running Minecraft. Within just a few minutes of gameplay, all 32 gigs of my RAM were completely used up by MC. Can anyone else confirm this behavior?

Flávio Alves 5 Reputation points2025-11-01T18:30:11.3466667+00:00 Same here, after a few minutes playing the game suddenly starts to increase the RAM usage up to 100%.

ROBERT PAULSEN 20 Reputation points2025-11-01T21:03:49.0733333+00:00 I've got likely the same problem. Minecraft is taking 27gb of my 32gb of ram.

Joshua Loera 40 Reputation points2025-11-01T21:08:24.9533333+00:00 I am also facing this issue. The game has been perfectly fine on my 32gb ram pc with high frames at 150fps+ for months. However, whatever update the game or launcher has been through. I have been getting frames like at 10 or less. Also, my ram usage was minimal like less than 16gb before. Now, it is using 30gbs+ of my ram and has been the problem of my gameplay. All my other games have worked perfectly fine, ran diagnostics over and over, nothing is wrong with my PC. They need to fix this issue as soon as possible. Nothing in game fixes it either, render distance, shaders, quality on fancy settings, simple settings. nothing.

2025-11-02T10:26:58.1833333+00:00 Tested other PCs running stock Windows 11 24H2 and I can confirm RAM usage on that system is normal. Only my Windows Insider machine is affected, and only in Minecraft.
After entering the world RAM usage rise to full 100% and stays there until the application is closed.No other game (Sniper Elite 5, DCS, Falcon BMS) or work App (Photoshop) does that.
I'm opening a bug on the MC Feedback website. -

Mark Abery 10 Reputation points Microsoft Employee2025-11-02T21:29:19.84+00:00 We have the same issue. Two fixes/workarounds so far. One - which i tried and works - is to switch to DX12 (by using RTX mode). The other is to turn off "reduce input lag" (I've not tested this yet. RTX does fix it if that's an option for you.

2025-11-02T22:05:24.29+00:00 Hey Mark. any help is indeed appreciated! unlucky me, I don't have any RTX capable card on any of my systems, so... can't confirm that.
I've tried disabling "reduce input lag" as suggested, and the game now feels less laggy and frames are slightly better (but far from normal). For me is still unplayable.
more important, the RAM issue is still there... 32gigs eaten by MC in seconds after logging into the world (both new and pre-existing).
But I'm thinking ... if going RTX solves, maybe it's a DirectX related thing...

2025-11-02T22:37:12.48+00:00 Hi everyone! Quick update: the 100% RAM usage issue has been resolved by turning off the "Improved Input Response" option and rebooting the game. The bug I reported to Mojang today has been redirected here:
https://report.bugs.mojang.com/servicedesk/customer/portal/6/MCPE-179496
Can you confirm if this solution works for you as well?
