Fallout 4 Precombine And Previs Guardian Mod v1.0.1

                    
Fallout 4’s Precombine and Previs systems carry a huge share of the game’s performance. However, a single incompatible plugin can silently disable them for an entire cell. Precombine And Previs Guardian stops that from happening in the first place. It runs as a native F4SE plugin with separate builds for each game version. Therefore, your load order keeps its intended performance instead of degrading from a hidden, undetected conflict.
What’s Included

Automatic Optimization Protection: Prevents Fallout 4 from disabling valid Precombine and Previs data when a plugin would otherwise break it.
Full Mod Compatibility: Leaves mods that correctly regenerate their own data unaffected, including new buildings and world edits.
Cross-Version Support: Ships as two builds, one for the Next-Gen update and one for the pre-Next-Gen version.
Optional Diagnostic Logging: Offers an issue-only logging mode for spotting problematic plugins, plus a full diagnostic mode.

Why You Need This Mod
Disabled Precombine and Previs data has long been a hidden performance killer in Fallout 4. Additionally, tracking down the guilty plugin afterward wastes hours of testing. This mod prevents the issue at the source instead. Therefore, you can install new mods without worrying they’ll quietly break a cell’s optimization.
