View Distance vs Simulation Distance

Compare view distance and simulation distance for Minecraft servers, including TPS impact, chunks, entities, farms, bandwidth, and safe starting values.

View distance and simulation distance are related, but they are not the same control. Confusing them leads to bad tuning: players may see farther than the server actively simulates, and that can be a useful tradeoff.

View Distance

View distance controls how many chunks players can see. Higher values improve exploration, screenshots, and open-world feel, but they increase chunk loading, memory pressure, disk access, and network traffic.

View distance affects:

  1. How far players can visually see terrain.
  2. How many chunks are sent to clients.
  3. How much chunk data the server keeps around players.
  4. How heavy exploration feels when players move quickly.

It does not mean every visible chunk is fully ticking all gameplay behavior.

Simulation Distance

Simulation distance controls how many chunks actively tick entities, random ticks, and block behavior around players. Lowering it can reduce CPU work while keeping a wider visible horizon.

Simulation distance affects:

  1. Entity AI and movement.
  2. Mob behavior near players.
  3. Farms and redstone expectations.
  4. Random ticking for crops and blocks.
  5. Server tick cost around active players.

This is why simulation distance often has a stronger TPS impact than view distance.

Suggested Starting Points

For many survival servers, start around:

view-distance=8
simulation-distance=6

For busy public servers, try lower values only after warning players and checking farms. For small private servers on strong hardware, higher values can be fine if profiling supports it.

You can generate a baseline with the server.properties generator, then adjust for your player count, world type, and hardware.

Watch gameplay impact

Very low simulation distance can affect farms, mobs, redstone, and player expectations. Explain changes before making dramatic reductions.

How to Tune Without Guessing

Change one setting at a time and compare profiles during the same player pattern. If MSPT improves after reducing simulation distance, the server was probably spending time on active ticking work. If network or chunk loading symptoms remain, view distance, pregeneration, disk, or routing may still matter.

Use the Paper performance settings guide for the next layer of tuning after these two settings are stable.

FAQ

Which setting affects TPS more?

Simulation distance often has stronger TPS impact because it controls ticking work, but view distance still affects chunk sending, memory, and player bandwidth.

Can I set simulation distance lower than view distance?

Yes. Many servers use a larger visual range and smaller ticking range to balance player experience and performance.

Do these settings require a restart?

Treat them like server configuration changes and restart cleanly unless your platform documentation says a live change is safe.
