Is there any updates on this issue from Microsoft/Mojang? or Nvidia?
this is also happening across v26.3 snapshots too..
so most likely a driver issue from Nvidia or Java or both I figure.
total freeze need a forced reboot no..
only the whole Windows GUI is lagging real bad.. could be an Nvidia driver bug…
a CTRL+SHIFT+Windows-Key+B will force a reboot of just the gfx drivers.. 😄
I was getting 160fps then the Java edition v26.2 would drop to 12fps or so after a few minutes or so..
totally UN-playable..
we have the same issue probably but different hardware..
maybe its a bug in the game than.
ooh so not even v26.3 has fixed it yet…
But your PC’s a laptop I take it, the system memory is a tad bit low.
and 1GHz.. how much system memory/RAM does your laptop have, David?
my desktop PC I upgraded from 32GB to 64GB of DDR4 RAM
and went from 16GB of DDR4 RAM in my DELL laptop to a nice 32GB of GSkill TridentZ
But you said it wasn’t lagging before v26.1?
nope I was mistaken, it happened again even when using a different resource pack a 128x.
so idk what it is Nvidia driver or game bug?
I have been able to play Bedrock edition fine.
its only the java edition that is having this issue and v26.2 too.
In my case I disabled an incompatible resource pack.

v1.21.q
it seems it was not fully compatible.. bummer.
the lag extreme went away and did happen on my modded client load..
hmm… so yeah.. at least in my case.
David rueda González, what graphics card do you have?
and driver version?
so the devs here can compare it to see what is going on.
hmm should I have opened a new ticket?
I am having this severe lag issue too on the v26.2 Java edition. modded and vanilla too.
It is soo bad that Windows explorer and the UI lags except for the mouse cursor..
but the latest bedrock edition worked fine…
I tried downgrading my Nvidia gfx drivers from v610.62 to v610.52 hotfix to no avail..
in the end either a full restart/reboot of the system or the CRTL+SHIFT+WinKey+B to force a reboot of the gfx drivers.. stopped the lagging but only if I shutdown Minecraft java edition first.

OS: Windows 11 Pro (x64)(v25H2)(Build 26200.8655) CPU: AMD Ryzen 9 3900X 12-Core Processor motherboard: Asus PRIME X570-PRO (BIOS_r5044 [01/04/2026]) Memory: 64GB, 2x G.Skill 32GB (PC3200)(DDR4-2137) Graphics Card: ASUS PRIME GeForce RTX 5070 12GB OC Edition, GPU by NVIDIA. so I have plenty of system memory/RAM and vRAM too I set my Minecraft moded install to 3GB XMX memory profile but it was using over that in Task Manager... so I may have to bump it to 4GB or 5GB of system memory.. but the issue appears to be out of dedicated vRAM.. race or memory leaks.
ooh ok so its not effecting me then ok thx for the info.
hmm interesting...
does this effect the cheat command /experience?
of course I gave my self exp 365 levels of it or so before I had any gear at the beginning of a new v1.20.4 world.
are the devs going to fix this a all?!
or will I be forced to continue with the workaround forever?!
No I'm not saying that...
I'm saying that this command line does works fine as a workaround.... but I should not have to resort to using it...
since a junction should being working just fine... like it did in all previous versions of the Minecraft Launcher...
with this issue only occurring in the MCL v2.0 and newer...
this is the modified shortcut I will be forced to use to keep my Minecraft running like normal..
F:\JoeGames_Minecraft\MinecraftLauncher.exe --workDir F:\JoeGames_Minecraft\.minecraft
This is the junction command line I use to create the junction I use...
junction "%AppData%\.minecraft" F:\JoeGames_Minecraft\.minecraft
please note that the %AppData% variable auto targets the roaming directory by default so its not needed in the cmd line...
Junctions can be downloaded from System Internals website here for testing..
https://technet.microsoft.com/en-us/sysinternals/bb896768.aspx
#MCL-5294 only explains so so...
MCL-5385 'Game directory is invalid or inaccessible' when a junction is used or an appdata environment path is used
#MCL-5385 mentions the use of junctions not working....
Mentioned in report 5294, this works as a work around.. but is simple not a good fix... as junctions are supposed to be transparent... and should not be affecting "C:\Users\UserFolder\AppData\Roaming\.minecraft" write location
"--workDir F:\JoeGames_Minecraft\.minecraft"
please reopen my ticket... and find a good fix for this, junctions worked just fine in all previous releases of the Minecraft Launcher...

Note the forward-slash instead of a backslash... is this just an typo error or is it effecting the launchers functionality as a part of this bug I am reporting on...??
This is the log file containing the references to downloading to AppData/Roaming and not writing/accessing to .minecraft folder....
it should be noted that I found this file in the correct location in .minecraft folder.... strange...
I grabbed the fresh v26.3 release and even with mods the lag issue seems to have gone away.. but I didn’t play for too long..
