Game Stuttering

[keithkay 1]

Hello, I have 530 hours in to this game and i obviously love it but lately the game has been stuttering for me. and its like full on 1 to 2 second stutter. I have i7 6700k 4.0 ghz 16 gb  ddr4 3000mhz ram gtx 1070 1tb ssd. playing the 41.50 iwbums. This never happened before but started lately. I am so frustrated. any advice?

This tends to happen on games where you live longer and you've visited a lot of cells around the map. This is what I do and it seems to work; you can increase the amount of RAM allocated to the game.

C:\Program Files (x86)\SteamLibrary\steamapps\common\ProjectZomboid
Look for the file "ProjectZomboid64.json" or "ProjectZomboid32.json" if you're playing the 32-bit version. Open it with notepad or notepad++

You're going to be looking for the lines that start with "-Xms" and "-Xmx" under vmArgs
I set mine to these values:
        "-Xms6144m",
        "-Xmx8192m",
Which corresponds to 6GB minimum(startup?) memory and 8GB maximum memory as opposed to the default of 1GB I think? Your system should be able to handle that just fine to be honest.

I find that I have to reset these values every single update so keep that in mind.

The Zomboid Devs might have better ideas of course

Could be the antivirus on your PC. Can you add an exception to it for the "C:\Users\YourUserName\Zomboid" folder? The game saves files in that folder and some antiviruses  keep checking those files nonstop, creating stutters.

Thank you for your advice but this happens from the very beginning of the game. Also i did change the ram allocation long time ago.

Thank you for your response but I am not running any antivirus.

I would double check, like I said, the RAM allocation you set in that file resets after every update so you have to re-apply it every time. Also this stutter can happen early game as well depending on how much ground you cover in-game.

Apart from that, maybe try doing a fresh install, or if you're using mods, eliminate the mods one by or - or start in vanilla and gradually add mods until you find a possible culprit.

Could you share your console log here? Just go to "C:\Users\YourUserName\Zomboid" and attach the "logs.zip" file to your reply here.
