Papyrus Tweaks NG v3.2.1

  • Renamed:  Main Thread Tweak and associated settings,  it instead is just “SpeedUpNativeCalls” because the current name doesn’t fit the current functionality at all anymore.
  • Fixed: the event order execution bug with a native cal speed-up tweak. The executing script calls on the main thread one by one changed the order events will execute in minor cases. In just very few scripts were super picky about this and bugged out (like Arniel’s endeavor and Alduin’s wall being the most noticeable examples). This is fixed now, thank you to everyone who reported this issue!


Take notes: Papyrus Tweaks NG requirements these mods below:

  • SKSE64 2.0.12 (VR), SKSE64 2.0.20 (SE), or SKSE64 2.1.5+ (AE)
  • Visual C++ Redistributables 2019 
  • Address Library for SKSE Plugin

This Papyrus Tweaks NG is a collection of fixes and tweaks to the Script Engine (not increase or decrease FPS at default settings.)

  1. Fixes: the bug fixes to the script engine.
  2. Tweaks: optional improvements to the script engine’s performance and logging.
  3. Experimental: not fully tested, understood or side-effect are unknown. It only enables you if you like to live dangerously.

These settings can be configured in PapyrusTweaks.ini (in Data/SKSE/Plugins). It automatically generates if missing and new settings will be appended to the file with feature updates.



  • Toggle Scripts Command Fix (default: enabled): toggle script console command pauses all scripts, and however not make persist when saving or stack dumping.
  • Negative Script Page Allocation Fix (default: enabled): Fixes the Papyrus Engine unintentionally allocating memory with a negative page size in some cases.


  • Max Operations Per Task (default: 500)
  • Disable Get Form From File Error Logs (default: false)
  • Improve Basetype Mismatch Logs (default: true)
  • Improve Validate Args Logs (default: true)
  • Disable No Property On Script Error Logs (default: false)
  • Disable Mismatch Script Error Log (default: false)
  • Stack Dump Timeout (default: 15000ms)


It defaults to false.

Speed up native calls (Formerly “Run Scripts On Main Thread”):

Scripts in Papyrus Tweaks NG will only run in tasklets that aren’t on the main thread most of the time, hence functions like “Game.GetPlayer” or “Formlist.GetAt” needing to be synced to framerate for thread safety.

The speeds up most of those in this experimental tweak call syncing them to a spinlock instead of framerate, greatly improving script performance for most scripts. By default, only the read-only/getter functions are sped up this way (ex: “HasKeyword”, “IsLoaded”, “GetWornArmor”, etc.) as they are much safer than functions that alter the game in any way (ex: “EquipItem”, “RemoveItem”, “MoveTo”, etc.) as those could have issues if run multiple times in one frame.

Bypass Papyrus Corrupted Save Check:

If loading is corrupted save, Skyrim can throw a message box saying “The save can not be loaded” despite already loading into the game. Because the game is missing some script data (not saved), but not in your current play session (ex: Uninstalling a mod and having leftover scripts in the save, but not in the game). So this experimental setting bypasses that callback that could normally kick you out of saving.

Warming: This will NOT fix a broken save, just allows you to load the save no matter what information is lost. ONLY USE AS A LAST RESORT TO RECOVER A SAVE YOU HAVE BEEN WARNED!!

Ignore Papyrus Memory Limit:

VN is stressed with over 100+ events queued up for processing, it will ignore any memory limit set iMaxAllocatedMemoryBytes until it can chew through enough events to bring that number down. So this experimental setting keeps ignoreMemoryLimit flag set (allowed to use as much memory as it needs all the time). If you plan to enable this, I strongly recommend getting Recursion Monitor. This setting also makes iMaxAllocatedMemoryBytes in Skyrim’s INI redundant.

Disable Scripts In Playroom (VR only)

Pauses Papyrus Tweaks NG scripts in the playroom in VR, and scripts running in the playroom have been causing incompatibilities with a lot of mods, like for example Live another Life. This experimental tweak keeps any scripts that don’t contain “vrplayroom” (VR Playroom has scripts that have to run to work properly) paused until you exit the playroom, and pauses scripts when going back to the playroom. Update: Tweak in Papyrus Tweaks NG will now not apply if the playroom is disabled, which fixes scripts breaking if you turned on this tweak, but don’t even use the playroom.
