Server-side only performance optimization mod for Vintage Story. The base game is already very much optimized, this is my attempt to speed up what's possible.

This can also benefit players in a singleplayer world, although much more limited.

⚠️ Testing Phase: This mod is currently in testing phase. Real performance gains may vary depending on your server configuration and game setup.

This is serverside only - if you want to improve your performance clientside, try OptiTime.

What it does

Less lag - 30-40% reduction in garbage collection pauses
Better performance - Especially with more players online
Lower memory usage - Saves ~15 MB per minute
No gameplay changes - Same game, just smoother

Performance gains

5 players: 20-30% improvement
10 players: 30-40% improvement
20+ players: 40-50%+ improvement

The more active your server, the better it works.

What gets optimized

19 optimizations targeting the most common performance bottlenecks:

Entity spawning/despawning
Block breaking and placing
Chunk loading/unloading
Physics updates
Inventory operations
Crafting and cooking
Water physics
Network packets

Commands

/tungsten - Show status
/tungsten stats - Show performance statistics
/tungsten stats on/off - Enable/disable detailed monitoring with CSV export (off by default)
/tungsten all on/off - Enable/disable all optimizations (except the monitoring tool)
/tungsten <name> on/off - Toggle individual optimization:
- blocklistreuse - Block Operations
- chunkloadingoptimization - Chunk Loading
- chunkunloadingoptimization - Chunk Unloading
- containeroptimization - Inventory
- cookingcontaineroptimization - Cooking
- depositgeneratoroptimization - Prospecting
- entitylistreuse - Entity Spawning
- entitysimulationoptimization - Entity Ticking
- eventmanagerlistreuse - Event System
- fixwaterfalls - Water Physics
- getdropslistreuse - Block Breaking
- gridrecipeoptimization - Crafting
- physicsmanagerlistoptimization - Physics Tick
- physicsmanagermethodlistoptimization - Physics Tick
- physicsmanagertoarrayoptimization - Physics Tick
- physicspacketlistreuse - Physics Updates
- sendchunkslistreuse - Chunk Sending
- sendplayerentitydeathsoptimization - Player Deaths
- servermainlinqoptimization - Player Queries

Changes require server restart.

Compatibility

Safe with:
- Content mods (blocks, items, recipes)
- Gameplay mods
- World generation mods
- All client-side mods

Troubleshooting

Server won't start?

Check server logs for errors
Try /tungsten all off to disable optimizations, then enable one by one to check which one causes it
Report the issue with logs

Performance worse?

Unlikely, but you can disable specific optimizations
Use /tungsten stats to monitor. You can turn it on/off to save measurements into a file with one, some, all or no optimizations enabled to have real numbers. You can send me these so I can investigate as well, the data is anonymized in the logs!

Mod conflicts?

Disable conflicting optimizations if needed

This might be coincidence but since install of this mod on my server the server has indefinitly not responded 2 or 3 times in the last 24hrs which it never did before. More weirdly there hasn't been an error or warning in the console just nothing no new entries etc..
Perhaps someone knows whats going on?

💬 Loginvvvvv, 3 days ago

I hope this helps with stutters I've been having

💬 Zaldaryon , 3 days ago

Eurielle if that mod changes some vanilla behavior, yes, it might cause a crash. You can disable the only setting it affects, though. This mod here was made considering the vanilla mechanics per se.

Dagurmawth if you provide me the crash log against Rustbound Magic, I can try to fix it on Tungsten's end.

💬 Eurielle, 3 days ago

According to a post on the Rustbound Magic mod it seems this mod and that one don't like each other. It appears to be related to Rustbound Magic's self-buffs but IDK exactly what the issue is as I haven't tested it myself. Just thought I'd give you the headsup on the present incompatibility though!

💬 Zaldaryon , 3 days ago

EthelVril handbook is clientside only. For that you can use the OptiTime mod that I made.

💬 EthelVril, 3 days ago

From my experience, the laggiest part of a modded playthrough is the handbook x.x

💬 Zaldaryon , 3 days ago

BraniyaKz and prototype464 try version 1.0.1 and tell me if it's fixed pls, it should.

💬 Zaldaryon , 3 days ago

WatermelonFrogy yes, I'm @zaldaryon on VS official discord.

💬 WatermelonFrogy, 3 days ago

This is awesome! We might test this out on Age of Seraphs once we update to 1.21! We currently average 50-60 on weekdays and 60-80 on weekends, 100+ during major events. Do you have a discord we could contact you directly on if we come across any problems?

💬 BraniyaKz, 4 days ago

Testing this on my singleplayer, and this exception keeps showing up in the server log:

💬 prototype464, 4 days ago (modified 4 days ago)

Loaded into a world by mistake, left, then went to load into another world and it sh*t itself upon trying to load, lemme know if you need more logs

Edit: Update, we found out Immersive Lanterns was throwing an OutOfMemory error because there were a lot of lanterns, I'm unsure if that caused this issue here.

💬 Zaldaryon , 4 days ago

Anthonyg1479, they're completely different mods, and you can use them together, yes, but the benefits of this mod is mainly for multiplayer servers (as in, for the server itself).

💬 Anthonyg1479, 4 days ago

Can i use this and your other mod OptiTime at the same time or is this just server side version of that mod?

💬 Ciber, 5 days ago

Trying now! I'm eager to see if this can squish my constant GC pauses in SP (which occure even though I have 32gig ram)
