This is a quick guide on how to fix the issue of intense lag when using mods.
What We Know So Far
If you’re already using mods then you’re probably facing a huge lag when playing followed by audio not playing or loading taking 3x longer.
This happens because PD3 requires you to add “-fileopenlog” to your game start options for you to be able to play with mods, but this configuration causes performance issues. Some players says to have fixed it by installing the game on a SSD, but since not everyone has one we need a workaround for it
First things first, remove “-fileopenlog” from your game start options
UE4SS / Allow Pak Mods
Download this mod: Mod Link
Right click PD3 on your Steam library and browse through the game files.
Head to “PAYDAY3\Binaries\Win64” and extract all contents from the .zip folder you downloaded in there. Should look like this:
Inside the mods folder you extracted there’s a “mods.txt” file.
Open it then find the line that says “AllowModsMod” and replace 0 with 1
Personal note: I’ve set all other mods in my .txt file to 0 and so far I didn’t got any issues ingame.
If you have any issues try setting everything to 0 except for “Keybinds” and “AllowModsMod”.
You’re all set to install mods and play.
To install mods (if this is your first time installing any) head to “PAYDAY3\Content\Paks” and create a folder named “~mods”. Then once you download your mods simply extract the .pak file inside it and you’re done.
Thanks for reading and big thanks to Narknon on modworkshop for uploading the mod.
This whole guide was created based on my own experience, which means I hope it helps and works for you the same way it worked for me.
