Trying the mod out in the most recent update.. game wont launch after editing bat and json file?

Is there a Mac OS version? I really need it!

Hey! I wish I could get this working on B42, but everytime I use this mod the game launches and I can get into the game itself, but upon interacting with anything my entire UI disappears, I can see it throwing tens of thousands of errors into the console.txt file, and attempting to pause the game does nothing. Followed the instructions to the letter with only this mod, same issue.

unclear installation guide from the notepad

@Gojita, for B41 you should go to the youtube video linked in description and download the files from there. It should contain the .bat .json and a guava file which is one of the dependency needed for the game exe, there is a version mismatch, so it fixes that.

@Jezo, sadly fps increase is not guaranteed, as you can read from the previous comments some people got really good fps increases some did not. This mod is not some magic, it just adds some java arguments so game tries to run better. If you have many mods installed you might get diminished results.

I can run the game but the fps still looks the same

b41 game is not working

B41 here, this one DOES NOT WORK , game doesn't even start. Both json & .bat file. For context, I've tried this on multiple PC of mine & even with dedicated server.

Lets be honest we are all here because our laptops/pc suck

applying the BUILD 41 FIX, the issue remains the same.

I’m hosting a server on my PC (not a dedicated server) using Build 41.
I applied the SERVER BUILD 41 files from YouTube, but I’m getting a "Server has stopped during launch (NormalTermination)" error, and the server won’t start.

Build 41 does not work on co-op mode. It terminates itself, adding server fix doesn't help either.

after initial impressions were good and stuttering seemed to be much better, im not sure whether i was just imagining it. game still stutters a lot when driving around and multiple zeds on screen with weather effects etc. but i am using quite a few mods so maybe thats just unavoidable. thanks

This is awesome, THANK YOU!

Build 42.10 Can be used Very good Thank you!

Hi hello! Great mod working well on all the client side. But I got a question. We hosting on a dedicated Server Nitrado. Really wondering If somehow this can be add into the server. Since Nitrado doesnt have StartServer64.bat in their file somehow.

this is woking

I get the error below when hosting non-dedicated server.
I have already downloaded the b41 fix in YT and placed it in the PZ installation folder.

@Scylde, it's client side. everyone who wants to use it should modify/change the default files with the modded ones

Not really seeing an increase in fps, but definitely see a reduction in stutters. I am running a I9 14900k and a 4070ti so that may be why I don't see any fps increase.

Is this host side or client needs to configure their own files?

Thank you for your wonderful work sir!. Can you make a version for MacOS? thank you very much!

amazing, no more lags even with 200+mods.

@JellyGoR, you can start it via steam, works just fine.

Should I start it from bat or steam?

This mod requires you to place the guava-23.0.jar file directly into your Project Zomboid installation directory, typically located at C:\Program Files (x86)\Steam\steamapps\common\ProjectZomboid. You'll need to obtain this file from the web for the mod to function correctly.

For any other installation steps, please refer to the modder's instructions. Following them precisely should ensure the mod works without issues.

If you encounter any problems, perform a Steam file integrity check, then re-add the guava-23.0.jar file to the Project Zomboid main directory. After that, follow the modder's instructions again. You shouldn't experience any major issues.

Thank you for creating this optimization mod! I'm finally looking forward to enjoying an optimized Project Zomboid experience with my friends.

@inverspe No it shouldn't cause any conflicts. What this mod does is basically add some arguments to the exe in java so it will utilize your CPU and RAM better. It's no different if you go and manually add the arguments. I have over 400 mods in my playthroughs and never noticed any conflicts or bugs related with this mod.

would this mod cause any potential incompatiblity with other mods?

@kps224, as long as you install it correctly, it wont cause any problems. If you don't install it correctly the first time all will happen is game wont launch that's all. There are couple of thousands of people currently using the mod as of right now that don't have problems.

Can someone check if this works? It won't cause game-breaking glitches or device problems?

@4Zeta
used the b41fix file from YouTube Unable to start the game，help thx

@irrelevantredundancy are the same but mine version autodetect hardware, and setting all avaible cores on low pc is not so good , i guess with a recent cpu is too much giving all cores , im using a 14700kf :)

@4Zeta La versione del gioco che sto giocando è la b41, ma dopo aver copiato e incollato i file del modulo B41 corrispondenti nella directory principale, il gioco non si avvia.

Hey! @4Zeta -- I've been using your improvements since they day you released this mod. I'm always looking around the internet for potential performance tweaks and I stumbled on a post that instructs us to add this to the launch parameters, and I wanted to ask you how it would interact with your version of the PZ64 .json.

-refresh 120-maxMem=12288-malloc=system-USEALLAVAILABLECORES-high

Will these commands coexist with/enhance/break what you have already done?


Quick Guide to Improve PZ Performance by @Sonov Belial

I use my PC to set up a B41 server and connect with friends. Do I need to install both B41 fix and Server fix at the same time? Where is the replacement file for the server located.

nn ho capito se qualcuno puo rispondere ma nello step uno dobbiamo selezionare noi le specifiche manualmente o copiare direttamente tutto il codice?? se domanda del kaiser perdonatemi ma so imbranato. capita

Well, it started up fine when I used the b41fix file from Youtube.Sorry for the trouble.

This log appears and it won't start...

Please teach me the solution...

I noticed worse performance after upgrading to Intel Ultra 7, does this work differently with CPUs that have P/E cores?

@frango if have some problem contact me :)

@Sqwerm thanks a lot for your help!

@Starfield if you arent able to check with right click the 2 files i cant do nothing :)
