@4Zeta: Hmm, I don't want to bother.. But it seems that it doesn't work for me, I've done exactly what the description says and it doesn't work for me, I've copied and pasted the two files, the ,ProjectZomboid64.json and the ProjectZomboid64.bat one you provide in the mod subscription itself, path: C:\Program Files (x86)\Steam\steamapps\workshop\content\108600\3459875383\mods\Multicpu Fix\41 and,.... because the game does not open. I'm doing it wrong?

If you need help add me on discord 4zeta

@Gojita, nope, ProjectZomboid dont allow that, so b41 youtube, b42 follow instruction here.

@4Zeta: Thank you! You already have a new subscriber on your YouTube channel! ^^

@Gojita now in the main page :)

@ShiroKureiji sorry just added now :)

@Miruoaser check the video tutorial or add me on discord

@4Zeta: Hello! I don't see the link to build 41 anywhere, could you provide it? Thanks a lot.

@4Zeta: Where is the YouTube link? or the instruction for B41 my friend?

@yaaago.davi doesnt works like that , add me on discord

so still not there but i made a copy with the exact same name and put the info that u put in the instructions

@yaaago.davi
C:\Program Files (x86)\Steam\steamapps\common\ProjectZomboid
this is the default folder

Check the Video Tutorial to install the mod :)

help i cant find projectzomboid64.bat

Video Tutorial on YT

@xfadedlover yes always :)

should i resub the mod?

@xfadedlover yup new instruction post b42.13.0
@the wok follow the new instruction post

new update rewrote my files back

okkk another update should i make any change?

aye aye

NEW VERSION UPDATED, B42.13.0 MULTIPLAYER,
WITH THE LAST UPDATED YOU NEED TO REPEAT THE INSTRUCTIONS IN THE DEDICATED POST!!!



If you can i need a benchmark video before and after... i need some to improve this mod for all !

No :)

so uh...i should change nothing?

@xfadedlover Nope i've updated only the old files..:)

new update should i update the bat and json file too?

@jestergamer101 yes use the link of yt

confirmed working B42

does this work for b41?

@JGuar for now is useless to give more than 12 gb of ram, now i allocate with this mod 10gb max
maybe in the next update i will put more.
This MOD is thinked for low bugdet PC

so the code is only if you have 16gb max what if you have 32gb? Will it auto detect that and adjust?

@Augustssy Done, i've resolved with the empty folder :)

I’ve found the cause: you need to create a “common” folder in the same directory as the folders named “41” and “42”—only then will the game recognize this mod properly

the mod dissapeared from my mod lists after my game crashed and i have spent hours searching online on how to fix this issue, so it was the new update that caused it? bruh i just wasted my time

你好 I see the last update was two hours ago. After resubscribing to get the update, I can confirm there are new icons in the mod folder, but the mod still doesn’t show up in the game’s mod list.

mod is missing from list after update

@B.I.G. 这个mod不光是订阅 还需要按说明手动修改两个文件的文本 我试过按作者之前给的文本修改后游戏无法启动 删除其中两行代码后就正常了
当然 现在作者好像已经修复了这个问题 按说明复制修改代码是没问题的

same, the mod disapear from the modlist

Hi! Since today the mod disapeared from the modlist. I tried unsubscribing and re-subscribing but no sucess.

@RayPlayST Hi! What does it do?

ProjectZomboid64.JSON
del:
"-Djogl.disable.openglcore=false",
"-XX:+OptimizeStringConcat"
B42.12.3 OK

@mac.edgar Thank you :)

The game is so much smoother. All the freezes and stutters have beeen greatly diminished. Thank you.

@Sui

No, it was basically massive lag upon transitioning into a high-pop cell from a low-pop cell.

And again, have it fixed or at least massively better. Get like a half-second or so hitch now, vs. needing to close and relaunch game previously.

No idea what I had done wrong.

As an FYI, I did get this working.

Thanks!

@jtcbrown If it's just one cell it could be too many items on the ground, I just stumbled on this mod hoping to fix that issue. It's a vanilla problem and there no mods to solve it that I've found, made worse by my lap potato. Only fix seems to be using containers and keeping them safe, maybe spreading them out more or limiting your hoarding habits to within your hardware specs.

@4Zeta Thank you for trying to fix this game, it's got so much potential but it's legit been driving me insane to try and get/keep it working.

450 mod single game. 330 fps in ravencreek nice!!!

I found that the game stuttered heavily while playing with 100+ mods, more heavily than I could accept. Looks like there's some details to be ironed out.

As of 11-25-2025 this mod is not working, I have backed up both files, enabled the mod prior to pasting the new .bat/.json, pasted the new files and it does not launch. Please fix as I love what these changes do for performance. Thanks!

@jtcbrown This type of stutter is sometimes caused by other mods like bandits, maps, or texture errors that keep writing to the file.
If you check the console file, you'll find the answer.
I use it on a hardcore server with 500+ mods with no problems.
