You have heard whispers of a legendary fix: the "Coolspear Simulation Lag Fix." But what is it? Is it safe? How do you get the version? And most importantly, does it actually work?
If your graphics card is running at uncapped frames (e.g., 200+ FPS), it can starve your CPU of the resources needed to run the simulation engine. Cap your FPS to match your monitor's refresh rate (usually 60Hz or 144Hz) via your graphics card control panel.

This system coordinates smoothly with custom game-time speeds set via MC Command Center. Step-by-Step Installation Guide
: For maximum effectiveness, the mod should be placed in your folder within the main Mods directory. Resource.cfg Update : You must replace your standard Resource.cfg
Speeds up autonomy requests so Sims react faster, which reduces the "simulation clog" that causes time to jump or freeze. www.reddit.com Step-by-Step Installation Post
