We have dropped Stable uGridsToLoad from the Guide. This mod has a memory leak which has never been fixed by the author. This was recently brought to our attention on the forums and we have promptly dropped this. STEP does not recommend changing uGrids from its default value (5)! We only recommend our INI tweaks and Dynamic Distant Objects LOD (DynDOLOD) to increase distant detail in the game.
We recommend you promptly remove this mod from your setups.
