Where Can I Change Minecraft Simulation Distance Meaning Settings?

On many servers the world’s behavior is decided server-side, so changing simulation distance locally won’t always do what you expect. From my experience hosting worlds, the reliable way to set it for everyone is to edit server.properties and change the line simulation-distance=, then restart the server. That sets how many chunks the server actively simulates for each player. If you need lower load for big player counts, reduce this; if you want remote farms to keep ticking, increase it carefully. There’s also view-distance in server.properties which controls how many chunks are sent to players for rendering — think of view-distance as what you can see and simulation-distance as what the game actually does behind the scenes.

If you're running a modded server or a performance-oriented fork like Paper, check its documentation: some offer runtime options or plugins that adjust tick behavior or per-world simulation. On client-side Java you still have a slider in Options → Video Settings labeled 'Simulation Distance', but the server can cap or override it. My go-to advice: for survival servers prioritize lower simulation on busy maps and use plugins for more targeted control; for singleplayer, find the sweet spot where your farms work but your CPU isn't melting.

Want to control how far the game actually runs mobs and redstone? I tinker with these settings all the time to balance performance and playability, so here's the clean, practical route. In Java Edition you open the pause menu, go to Options → Video Settings, and you'll find a slider for 'Simulation Distance'. That slider defines how many chunks around you will be actively simulated (mobs, farms, redstone ticks). Lower it to save CPU and reduce server load, raise it if you want distant farms or mob behavior to keep working while you’re exploring. On Bedrock Edition the setting is in Settings → Video (or Graphics) as 'Simulation Distance' as well, though the UI looks different across platforms.

If you're on a multiplayer server, remember the server controls the effective simulation distance. The server.properties file has a simulation-distance value you can edit (and then restart the server) — that takes precedence over a client's slider. There's also 'view-distance' which controls how many chunks are sent to clients for rendering; the two interact but are not the same. Spigot/Paper servers and forks sometimes expose more granular options in their configs or via plugins that let you tweak or change things without full restarts.

Practical tips from my play sessions: keep simulation distance low on crowded or low-spec servers (2–6 is common), bump it up for singleplayer or if you rely on distant farms (7–10). If redstone or mob farms stop working when you travel, it's likely your simulation distance is too small. Tuning this is the single best tweak for smoother gameplay without sacrificing too much of the world’s life—I've seen big FPS and server-tick improvements just by nudging that value down a few chunks.

I like quick, practical fixes, so here’s a short walkthrough I use every time: if you're playing Java Edition, press Esc → Options → Video Settings and slide 'Simulation Distance' to change how far chunks are actively processed. On Bedrock, hop into Settings → Video and tweak 'Simulation Distance' there. If you're on a multiplayer server, edit server.properties and change simulation-distance=VALUE (then restart) — the server setting usually wins over The Client. Don’t confuse this with 'view-distance' which only affects what you can see; simulation distance affects mob AI, redstone, and farms.

Lowering simulation distance saves CPU and reduces server lag but can stop distant farms and redstone from working; raising it makes the world feel more alive at the cost of performance. For most setups I aim for a middle value that keeps essential farms running without frying the CPU. Personally, I tinker until I find that comfy balance and enjoy the smoother gameplay.
