Tungsten

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.

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

I follow RERO (Release Early, Release Often) philosophy.

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

Tungsten currently ships with 27 optimizations:

• Entity list reuse
• Block list reuse
• Get drops list reuse
• Event manager list reuse
• Chunk loading optimization
• Chunk unloading optimization
• Entity simulation optimization
• Cooking container optimization
• Container optimization
• Grid recipe optimization
• Propick reading optimization
• Send player entity deaths optimization
• Physics manager list optimization
• Physics manager method list optimization
• ServerMain LINQ optimization
• Placeholder optimization (suggestion by tehtelev)
• Wildcard fastMatch optimization (suggestion by tehtelev)
• GetEntitiesAround optimization
• Entity despawn packet optimization
• RecipeBase LINQ optimization
• Broadcast LINQ optimization
• Bulk entity attributes packet optimization
• ClassRegistry frozen optimization
• GetPlayersAround optimization
• GenTerra zero-alloc optimization (new in v1.3.4)
• GenTerra BitArray optimization (new in v1.3.4)
• GenTerra native noise optimization (new in v1.3.4)

Compatibility

Works with almost all mods. 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
• Report the issue with logs

Performance worse?

• Unlikely, but you can disable specific optimizations
• Use /tungsten stats to monitor

Mod conflicts?

• Disable the conflicting optimization individually
