Opticores is a client-side mod that works with Embeddium and Sodium on (Neo)forge and Fabric for 1. 21.x, made to fix the bottleneck that integrated graphics (Intel UHD) and low-end devices.

### Performance — Minecraft 1. 21. 1 (Cherry Grove) Test system: Intel i3-1115G4 (2 Cores/4 Threads) • Intel UHD Graphics • 16 GB RAM (2133 MT/s)

| Comparison | Min | Avg | Max | |---|---|---|---| | Sodium vs Vanilla | +1400% | +227% | +71% | | Sodium + OptiCores vs Sodium | +180% | +84% | +55% | | Sodium + OptiCores vs Vanilla | +4100% | +500% | +166% |

## How it works:

- Asynchronous Culling Pipeline (ACP):

Distance and frustum intersection math moves off the main rendering thread onto a background worker instead of blocking each frame.

- Concurrent Data Management (CDM):

The culling output is stored in a thread safe ConcurrentHashMap so the render thread reads the chased result instead of reloading it every frame.

- Dynamic Load Throttling (DLT):

Monitors chunk loading and temporarily scales back entity rendering during harsh world loading, teleporting to a new area, so the terrain generation gets priority.

- Compatibility:

Bypasses for custom block entities like Create’s and coordination with Distant Horizons or Voxy to avoid culling conflicts during LOD making.
