Lag spikes while using builder tools | Axiom | Page 1

Hello. Recently I have been getting lag spikes when using any builder tool. When I use extrude, move, clone, erase etc I get lag spikes that make it very frustrating to use. Especially when building quickly with extrude. (Also, this issue isn't only with big selections. The lag spike is the same length whether is 1 or 100 blocks.)

Now, here is what I think is the culprit. This issue only started after I reinstalled windows on my computer. So I know that this issue probably has to do with that, but I haven't had any issues with my PC at all. This is the only issue that has popped up since the reinstall.

I play with a lot of client side mods, but I have also tried testing this issue on a fresh Minecraft instance, only using Fabric API & Axiom. The issue persisted on both instances equally.

Ill provide any details y'all need. But here is what I can think of:

Minecraft 1.21.4
Fabric 0.16.14
Axiom 4.8.0
Fabric API 0.119.3+1.21.4
Dedicated RAM 8gb
Updated all essential drivers for PC
GPU: 4070 TI Super
CPU: AMD Ryzen 9 7950x3d 16 core
Total ram: 32
Installed MC on my SSD
Windows 11

I know this issue may boil down to a Windows issue, but I honestly have no other issues than the Axiom lag spikes. So I didnt know how to research / fix this problem without asking here. Appreciate any advice! :)

#

I also did simply try resetting the PC too. No fix. I am not super tech savvy so I am sorry if this is is a silly thing to be posting here. I just have no clue how to fix this.

how big of a lag spike are we talking?

spiral rover Jun 9, 2025, 8:13 PM

#

Ill record a vid for you

distant hound Jun 9, 2025, 8:13 PM

#

you just reinstalled windows? no hardware changes right?

#

distant hound you just reinstalled windows? no hardware changes right?

Correct

#

Recorded that on the fresh instance of MC. It is the exact same with sodium + client side mods

you could run a spark profiler

spiral rover

this is literally unplayable yooo

spiral rover Jun 9, 2025, 8:18 PM

#

Will do

distant hound Jun 9, 2025, 8:18 PM

#

/sparkc profiler start
/sparkc profiler open
or something like that

spiral rover Jun 9, 2025, 8:20 PM

#

is this right? https://spark.lucko.me/fE5izgn7xv

I reproduced the lag spikes while running the profiler

allocate more memory

spiral rover Jun 9, 2025, 8:21 PM

#

wait what?? i set it to 8 gigs i see that it says 788mb

#

I use prism launcher... maybe it didnt save my allocated mem?

#

distant hound Jun 9, 2025, 8:22 PM

#

yeah I see now

spiral rover Jun 9, 2025, 8:24 PM

#

distant hound Jun 9, 2025, 8:26 PM

#

thought it looked like garbage collector lag spikes
idk how to read flamegraphs

spiral rover Jun 9, 2025, 8:26 PM

#

Hmmm

distant hound Jun 9, 2025, 8:29 PM

#

you could try using -XX:+UseZGC -XX:+ZGenerational -XX:+AlwaysPreTouch -XX:+UseStringDeduplication with a java version that has a zgc like temurin

#

other than that youll have to wait for Moul

spiral rover Jun 9, 2025, 8:32 PM

#

distant hound you could try using `-XX:+UseZGC -XX:+ZGenerational -XX:+AlwaysPreTouch -XX:+Use...

Sadly no change. Unless I did it wrong.

distant hound Jun 9, 2025, 8:33 PM

#

and it worked perfectly fine before the fresh install?
with the same settings?

spiral rover Jun 9, 2025, 8:34 PM

#

Yup. Same settings and everything. I backed up my MC on a seperate harddrive so I wouldnt have to manually tweak everything after the reinstall. Exactly the same instance of MC

distant hound Jun 9, 2025, 8:34 PM

#

what gpu driver are you using?

spiral rover Jun 9, 2025, 8:35 PM

#

576.52 (nvidia)

distant hound Jun 9, 2025, 8:37 PM

#

did you have an older driver before?

spiral rover Jun 9, 2025, 8:38 PM

#

Hmmm I dont believe so no. I keep my drivers up to date. The driver version was released may 19th and that was before i reinstalled. I reinstalled windows 5 days ago. (wouldve noticed this issue earlier but i am just now testing mc today)

#

I just had an idea. One change was that I installed the Nvidia app. I noticed it has global settings for my graphics. Maybe one of these settings is doing something funky? (before i used geforce experience)

#

#

but thats my only idea.

distant hound Jun 9, 2025, 8:41 PM

#

its only a nicer looking control panel with built in bloat
nothing that should affect your performance

spiral rover Jun 9, 2025, 8:41 PM

#

love built in bloat.

distant hound Jun 9, 2025, 8:42 PM

#

at least I didnt use most of its features once I tried it
msi afterburner and getting graphic settings off of reddit or something is nicer

#

wth is geforce experience

spiral rover Jun 9, 2025, 8:43 PM

#

distant hound wth is geforce experience

It was nvidia app before nvidia app.

distant hound Jun 9, 2025, 8:43 PM

#

I see

spiral rover Jun 9, 2025, 8:45 PM

#

Well i will wait and see what Moul has to say. Until then i will keep researching on my own and hope to stumble across a random fix :P thanks for your help. Lemme know if u think of anything :)

distant hound Jun 9, 2025, 8:46 PM

#

and the lags only occur when using axioms tools?
normal minecraft, fill commands and quickly placing blocks works fine?

spiral rover Jun 9, 2025, 8:48 PM

#

Lemme check that. didnt think of that

#

Nope no lag at all. /fill works and placing blocks quick is smooth as butter

distant hound Jun 9, 2025, 8:51 PM

#

send minecraft/logs/latest.log of the client

#

after that its for Moulberry to look at

fierce treeBOT Jun 9, 2025, 8:54 PM

#

@spiral rover (Ronnoc09) uploaded a log,

Fabric 0.16.14 on 1.21.4 using 3 mods

spiral rover Jun 9, 2025, 8:55 PM

#

I reproduced the bug for the log.

#

i did another spark profiler and i noticed the more I use i use the extrude tool, the higher my memory useage jumps. https://spark.lucko.me/ldYbrQ1XPf
like i got it to 90% for a sec while using it pretty fast. in the past it wouldnt lag me so i wonder if its a ram issue?

spark

#

like maybe while i was reinstalling windows, something weird happened to my ram ?

distant hound Jun 9, 2025, 9:03 PM

#

unstable ram?
did you do overclocking?

#

how many ram sticks do you have?

spiral rover Jun 9, 2025, 9:03 PM

#

no overclocking. I got two ram sticks.

distant hound Jun 9, 2025, 9:04 PM

#

what are the specs of the ram

spiral rover Jun 9, 2025, 9:05 PM

#

I got TC T-create ram
DDR5 2x16gb
6000mhz

#

i have warranty on my ram so if i need to return it i can do so. but still so odd cuz other games work perfectly fine. Marvel rivals for example runs perfectly smooth. no issues whatsoever

#

And like everything else in MC from my knowledge runs super smooth. I get great fps and gameplay stability. It is simply just Axiom from my knowledge.

distant hound Jun 9, 2025, 9:08 PM

#

yeah thats probably not the issue anyway
I mean you could run ycrunsher for a few minutes to check
but I would just wait for Moul

spiral rover Jun 9, 2025, 9:08 PM

#

Ill just wait for moul. Until then ill just play MC and see if i can reproduce the bug in other ways to get more info.

spiral rover Jun 9, 2025, 9:56 PM

#

My memory useage is going from 10% and then slowly up to 95%.. Then all of a sudden goes straight down to around 10% again. I know this is garbage collection from java, but is 95% too high? is this what may be causing my issues?

distant hound Jun 9, 2025, 9:58 PM

#

is this with the java args I gave you?

spiral rover Jun 9, 2025, 9:58 PM

#

Yup

distant hound Jun 9, 2025, 9:58 PM

#

try without

spiral rover Jun 9, 2025, 10:00 PM

#

Ah yea that made the memory issue more stable. The main issue still persists tho obviously. but hey atleast im not 95% memory useage

#

thx

spiral rover Jun 9, 2025, 11:41 PM

#

Also for when moul reads this, i just tried changing most vanilla MC settings to different values. render distance, vsync, and all the other settings etc etc. nothing changed.
