Performance Tweaks

Recommended Posts


Space Engineers is a great game. I find that it really makes me think about what i am doing and how it is going to affect my playing style. One of the things i have noticed is that there are Question around Performace and Game Speed. ( Sim Speed ) .I found this on the net and am re-posting it here. While it is a little old, the message still holds value.

As always there's a lot of people asking how to improve FPS in game and recently I've been copy pasting previous comments so I thought it would be a good idea to get all of our performance improving tips in one place!
These are tips to help you improve your FPS. Only use the ones you are capable of. I won't be held responsible for any damage incurred from using these tips. (I will try to cover safe operation of any tips that warrant it.)
1. Interior Lights are far less CPU intensive than spotlights as they don't cast shadows.
2. Blocks that require power or transport items have a much bigger performance impact than regular armour blocks. Use them sparingly.
3. Blocks that aren't finished building require much more processing power than finished blocks. (They have more polygons and the game can’t do visibility optimizations.)
4. The less blocks you use the better it is on system performance so use large ships over small ships where possible.
5. Fixed place stations require much less CPU power than mobile ships. (Putting all your economy into a stationary base will reduce the size of your ships and thus the CPU hit of flying about.)
6. If you aren't playing in a planet enabled map, disabling cargo ships will improve CPU/RAM as cargo ships spawn 10km out and the game generates all the surrounding space as they travel near you.
7. Lots of objects will slow down the game such as loose bits of ore, damaged parts of ships and random "loose" blocks.
8. Disabling asteroid storms under the "Environment" setting will improve FPS due to avoiding terrain/block deformation.
9. Disabling "Thruster Damage" when starting a new game will improve FPS as the game no longer needs to calculate damage and deformation effects.
Graphic Settings:
1. Reducing almost any graphic setting will improve your FPS. (Except Field of View.) If you play on planets then reducing Flora will give a big bonus and disabling it on starting a new game more so.
2. If you get good FPS but your GPU is running hot check the "Vsync" option. This will limit the in-game FPS to that of your monitor refresh rate. For example, in some games (not SE) if I have this option un-ticked my GPU can go as high as 150fps but my GPU is running at close to 80 degrees. When I enable Vsync my FPS is limited to 60, I can't see any difference in actual gameplay but my GPU is now running close to 55-60 degrees using less power and making less noise. (Enabling Vsync will not cause any issues if you have low FPS.)
1. Less drills = more FPS: Large Drill Big Radius: http://steamcommunity.com/sharedfiles/filedetails/?id=464843314
2. Less blocks = more FPS: Block Optimizer: http://steamcommunity.com/sharedfiles/filedetails/?id=516017091 (Great for bases and large ships!)
3. Less Polygons = more FPS: LowPoly Conveyor: http://steamcommunity.com/sharedfiles/filedetails/?id=522154343 (They don't look pretty but can be easily hidden.)
4. Less functional blocks = more FPS: Tiered Blocks: http://steamcommunity.com/sharedfiles/filedetails/?id=508161635 (Instead of using multiple solar panels you can just use a single more powerful one for example.)
5. Interior Lights with vastly increased range: Extreme Lights: http://steamcommunity.com/sharedfiles/filedetails/?id=441277694
6. Removes the edges from armor. Some have reported an FPS increase. No Armor Edges: http://steamcommunity.com/sharedfiles/filedetails/?id=300685868
1. Clean hardware runs cooler and won't throttle down mid-game. De-dust your GPU/CPU every 4-6 months. (Advanced users only.) Guide: http://www.ehow.com/how_4795699_clean-dust-off-video-card.html
2. Ensure your hardware drivers are up to date.
3. SE currently only uses one CPU core so higher clock speeds are more important than the number of cores in your CPU. (Note: SE is VERY CPU intensive.)
4. SE uses a lot of memory so try to make sure you have 8GB+ of RAM. If you get errors regarding insufficient memory, dropping your texture quality will help tremendously.
1. Closing other programs while SE is running will free up more memory/CPU.
2. Disabling security auto-scans will free up CPU. Running anti-virus etc scans take up a lot of CPU, disable auto-scans and run them when you're not gaming.
3. If you don't have an SSD but a regular Hard Drive, defragmenting your PC every year or so can make an improvement. (This is hotly debated but in my experience I have seen an improvement with other games.)
4. Disabling start-up programs will reduce the time it takes your PC to start up and reduce the number of programs you may need to disable to improve game play. Guide: http://www.howtogeek.com/74523/how-to-disable-startup-programs-in-windows/
1. SEToolbox is a very useful utility created by the SE community which players can use to delete floating objects that create lag. (Highly recommended after long gaming sessions.) Can be found here: https://setoolbox.codeplex.com/
Space Master Mode: (Server Admins Only)
1. The Space Master (accessed by pressing ALT+F10) empowers server admins to better maintain their servers or to enforce the server rules and create a game environment on the fly (think Dungeon Master). It enables them to teleport where they want, spectate in worlds with a disabled spectator, setup custom trash removal, or manually cycle through ships, stations and characters and then have them deleted, de-powered or stopped.
Unofficial Tips: (Those that work for some people and we just don't know why!)
1. Some players have reported better FPS using medium/high textures rather than low. It is possible that your CPU is being used extra to compress/decompress the textures when they are set to low - this saves RAM but could impact your FPS.
