⚡Performance(21)
- fixClient staging measurements show 0.1% low frame time down 2.51ms, 1% low down 1.17ms, median down 0.54ms, about 1.6GB less memory and garbage collection about every 12 minutes instead of 6.
- fixBuilding privilege checks use a block grid instead of repeated physics queries, reducing a large-base check from 5.7ms to under 0.02ms on server and client.
- fixGun effects are prewarmed and optimized, including fixes for sound cutoff hitches up to ~1ms and muzzle flash checks up to ~7ms; effect pooling saves ~30MB.
- fixBase loading optimizations include faster entity spawning, off-thread industrial pipe meshes, pooled deployables and LOD work spread across frames, plus LOD, culling and batching fixes.
- fixReduced gameplay memory allocations make garbage collection and associated lag spikes less frequent.
- fixSound occlusion is over 10x cheaper outside a base and sounds allocate almost zero memory when played.
- fixDeep sea content loads on entry and unloads on exit, saving ~260MB of RAM outside it; modded servers load it when needed.
- fixOnly terrain textures for the current environment and quality level remain loaded, saving 138mb at the highest quality level.
- fixFlashlight and laser processing is optimized, with the new laser solution handling 5x as many lasers at a 0.125ms budget.
