Space Engineers: Server Optimizations
- New Server Optimization Features:
- Tiered Update System
- Selective Physics Updates
- Faster and more responsive DS GUI
- New localizations
We are pleased to present you with a very special update that focuses on server performance.
Multiplayer enthusiasts, and especially Server Host/Administrators, will want to read on in order to learn about the new systems we are implementing. These changes are focused on improving the overall player experience of servers and will have a bigger impact on larger, more populace servers.
What can you expect from this multiplayer update? Better performance translates directly to bigger servers! With these new server-side optimizations, players should now experience less slowdown on larger, more populous, servers. PCU limitations can now be pushed farther as the server can better handle more active grids!
Along with server performance, we are proud to offer better localization! Expanding the languages you can play Space Engineers in has been a goal for some time and we are excited to finally be able to offer a better experience to players across the globe!
Tiered Update System
We have added a new grid system, which we call the “Tiered update”. This system has two states:
- Grid presence
- Player presence
Grid presence: This is the grid state when another grid is nearby.
Player presence: This is the grid state when any player is nearby.
Tiered Update: This new grid system assigns these states to the grid/blocks and can change behavior based on that information.
Replicated and Not Replicated
We added new Replicated and Not replicated filters to the admin Entity list section to provide information for the server admin. There is also general information about states in the provided tooltip.
Modders can also use this system. We have added new properties and events on IMyCubeGrid and IMyFunctionalBlock interfaces.
Selective Physics Updates
The Selective Physics Updates is a new optional system. This system is only for dedicated servers and can be enabled in the session settings (Enable Selective Physics Updates).
This system observes all of the existing worlds (Havok physics engine has more than one in SE) and, based on player presence, detects which worlds need to be simulated.
The net result is that only worlds around the players on the server are simulated (physics). This optimization makes a notable difference, especially for a really big server with a lot of grids.
With Tiered Update we added a new update timer to several blocks. This update timer is changed based on player presence and grid presence. This timer determines how often a given block needs to be updated.
There were changes to the following blocks:
- Gas Generator
- Gas Tank
- Turrets and Barrels
- Ship Controller
- Landing Gear
- Production – Refinery and Assembler
Some of the above blocks will update less often, even for normal states (player presence, grid presence). Changes have a minimal impact on the gameplay.
Changes and fixes
We refactored and disabled some features(code), which do not need to be run on the server. Especially for the character, hud, toolbar, parachute and ship controller.
Trash cleaner is not only cleaning asteroids (to the point of removing entities from the game) but also stones now. We have added a new option for this.
Trash cleaner (identity cleaning) is now more thorough and cleans data which is no longer needed such as reputation, bank account etc..
We refactored and cleaned up the process of the player joining the server and, overall, this process is much faster.
- The joining process now sends less data.
- The process is no longer on the main thread (parallel).
- For big servers, there is no longer a spike on the main thread (for other players).
- Fixed a “drop container” network issue. Server was sending too much information in some cases.
Other Changes and Features
You can customize the color of any player made GPS.
There is a new Family Sharing option for dedicated servers to allow/disallow family shared accounts on the server.
There is a new PCU Trading option for dedicated servers to allow/disallow pcu trading on the server.
As part of our continued development, we are currently in the process of updating the collision models of every block in-game! We believe these changes will offer a boost to how old creations perform as well as providing a whole new set of creative possibilities!
Performance Comparison – 1.195 vs 1.196
We are very excited to share the results of a number of internal tests we have conducted on some of our own Official Keen Software House servers! Below are a series of performance tests run on both 1.195 and 1.196 worlds.
As you can see, the main thread shows a significant decrease in load, from around 90% to 60% on UK#5, and an even greater decrease in overall load when Selective Physics Updates is active!
Yellow: 1.196 with “Selective Physics Updates”
New localized versions
Space Engineers had three official language localizations up until this moment. It is English, Russian and Chinese – simplified. We are glad that with this release we are bringing the game closer to all our fans who speak Spanish and French.
We also updated community translations for German, Italian and Brazilian-Portuguese. Enjoy the game!
How is this different from other performance solutions for dedicated servers?
There are 3rd party solutions offering performance boosts. Our solution is an additional way to make your server faster, not a replacement. If you are using a 3rd party tool for your dedicated server, you will see better performance overall with Major Update 196.Q:
Are the server optimizations going to positively contribute to the future of Xbox multiplayer?
Many of the changes that were made for Space Engineers, on Xbox, became improvements on the PC platform, and vice versa. As we continue development of Space Engineers, on both PC and Xbox, we will see improvements on both platforms. Xbox dedicated servers (once implemented), for instance, will benefit directly from these improvements.Q:
Multiplayer performance is always a high priority. Optimization is an incremental open-ended process. As we continue development we are always striving to find new ways to improve your Space Engineers experience.
Q: Will these changes affect multiplayer lobbies or single player?
A: No, these changes have been created specifically for dedicated servers. Larger population servers and higher traffic servers will have the most to gain from this.
Q: I don’t see my language on the list. Are you still planning to add (more) new languages?
A: We are always considering new localization options and better ways to cater to our community. While your language may not be supported now, as ever, we will continue to deliver new, official, translations. We think everyone should have a chance to be a Space Engineer!

What is the community saying?
The new block collisions will allow a whole new level of creativity from the community, an amazing change with unlocking even more potential within SE.

This is brilliant. Surprisingly the server I use is not incredibly stable and I have to admis this is great news. Well done Keen Software love it.
This update is just the kind of QoL thing SE needs right now. New features and content are great, but every once in a while you have to improve the core experience. Looking forward to the next one!
~ Daniel Lee Howell
Would just like to say well done this update it has made such a huge change that I feel it has just redefined the game. Well done.
This is literally a game changer.
