What is simulation distance in minecraft ? Minecraft 1.18 update has a number of experimental settings, including simulation distance settings and a few other game updates. The simulation distance setting affects how far away things can be while the game continues to either play out the processes the item is undergoing, such as items smelting in furnaces, or how far away mobs will continue to think and have AI.
If this distance is too far, or there are too many players simulating totally distinct areas, the performance of the game can start to lag and even come to a stop in serious cases. This means that appropriate simulation distances are vital to keeping the game running as efficiently as possible.
Exploring the ideal simulation distance in Minecraft
A singleplayer world only relies on the player’s computer and must only calculate the mathematics and run simulations for a single person. This means that, assuming a player’s computer isn’t strong enough to adequately run a higher simulation distance setting, there really is no reason not to.
It is important to note that any farm, AFK or otherwise, outside of the simulation distance of the game will cease to function. But since chunks operate at full world heights, players can potentially stack farms above one another up to the build cap. The simulation cap does not matter, so long as the player remains in the chunks directly below them.
Ideal simulation distance for servers
Since a server or realm has to do all the in-game calculations for every single player in the game, the simulation distance settings can cause major issues. If each player has their simulation distance set to a high number, and they are all in completely different areas of the world, there will be noticeable lag on the server’s end, unless the server is running on a very high-end CPU.
While the impact of large simulation distances is minimized so long as players remain near one another, the potential issues mean players should keep the simulation distance to a minimum. Otherwise, settings can also be implemented that would allow the server to enforce a simulation distance cap and keep potential server lag to a minimum.
What is simulation distance in Minecraft?
Simulation distance is an important gameplay setting in Minecraft’s Bedrock Edition that determines how much of the game world is loaded and processed each time around. The simulation distance essentially controls how far out from the player’s current position the chunks of blocks, mobs, and other features are loaded. It works by specifying a radius around the player’s current position and then loading the blocks and other features within that radius.
How to change simulation distance in Minecraft?
Changing the simulation distance in Minecraft is relatively simple and can be done from either the game’s main menu or from within a world. To change it from the main menu, simply click on „Options” followed by „Video Settings” and then „Simulation Distance”. This will bring up a slider that can be adjusted to select the desired simulation distance.
To change it from within a world, press Esc and then select „Video Settings” followed by „Simulation Distance”. Again this will bring up a slider that can be adjusted to select the desired simulation distance. Once you’re happy with your selection, click „Done” and you’ll be ready to go!
It is important to remember that the higher the simulation distance, the more resources the game will require from your computer. Therefore it is recommended that if you are having performance issues in Minecraft, you should try reducing your simulation distance. The lower the simulation distance, the smoother and more stable the game will perform. Therefore it is important to find a balance that works for you and your computer’s hardware capabilities.
How can changing the simulation distance affect your game?
Changing the simulation distance can have a major effect on your game’s performance. The higher the simulation distance, the more blocks, and features will be loaded in at once, which means that more processing power is required to keep up. This in turn can lead to stuttering, lag, and other performance issues if your computer doesn’t have enough processing power.
On the other hand, a lower simulation distance can potentially improve performance and offer smoother gameplay. This is because fewer blocks and features are loaded in at once, so the game doesn’t have to do as much work. However, it should be noted that reducing the simulation distance too much can result in missing blocks and features in the game world, so it is important to find a balance that works for you.
What is Simulation Distance in Minecraft?
Simulation Distance is a setting that has existed in Minecraft Bedrock Edition for years but was only added in Java Edition with the release of the Minecraft 1.18 update.
In a nutshell, Simulation Distance is a setting that determines the maximum distance from the player where the chunks are ticked (updated). This means that the Simulation Distance setting defines the area around the player where the game actively simulates and processes entities and various game mechanics, such as the growing of crops, spawning/despawning of mobs, flowing of water, etc.
So despite the setting being overlooked by most players, Simulation Distance is actually one of the most important settings in Minecraft.
How Does it Work?
If you want to fully optimize Minecraft’s performance on your system, you must have a good grasp of how this setting works. To make things simpler for you, let’s start with an example.
Let’s say you have your Simulation Distance set to 4 chunks in Minecraft Java Edition. When you stand within your chunk, which has a 16-block radius, the Simulation Distance will simulate a 9×9 square of chunks around your chunk. This means that within those 81 chunks, mobs will spawn and despawn, crops will grow, water and lava will flow, villagers will breed, and any automatic farms you’ve set up will function as intended.
But, one interesting thing to note is that one more chunk out from that 9×9 square of chunks—forming a one-chunk layer around those 81 chunks—the game mechanics such as redstone, crops, and liquids will work as intended. However, the entities will not be updated. Thus, mobs such as zombies, skeletons, villagers, and other entities like minecarts, exploding TNT, and falling sand, will be frozen in place.
And then finally, in all the chunks beyond that, absolutely nothing will be updated or ticked. So no mobs will spawn or despawn, no crops will grow, no redstone will work, etc.
Note: Mobs that already exist in the chunks outside the simulated zone will continue to exist and will count towards the mob cap, despite not being able to interact with the world.
I know this all sounds very confusing, but I can assure you that it’s way simpler than it seems. Let me explain it to you visually.
In this screenshot, imagine each block represents one chunk (which is 16x16x256 blocks). Let’s say that you are standing on the green chunk and have your Simulation Distance set to 4 chunks.
In the white-colored area, all game mechanics will be updated, and all entities will be ticked. This means that all entities will spawn/despawn and move around, water/lava will flow, crops will grow, fire will spread, and redstone will function. So any farms you have set up in this area will work perfectly.
But in the blue-colored area, the entities will not be updated. So any mobs (and other entities such as minecarts) present in that one-chunk-thick layer will be frozen in place, and no mobs will spawn/despawn. However, everything else will work normally; so crops will still grow, redstone will keep working, and fluids will still flow.
And everything beyond that (represented by the black-colored area) will not be simulated/updated/ticked. Meaning that absolutely nothing will work in those chunks – whether that be mobs, crops, liquids, or redstone.
