Iridium

Iridium 0.1.0 — Initial Release

First release of Iridium — an optimization mod for Minecraft 1.21.1 (Fabric).

What this mod does

• Entity Culling — entities outside the camera frustum are skipped during rendering
• Particle Culling — particles outside the frustum are ignored; simultaneous particle cap enforced
• Block Entity Culling — chests, furnaces and other block entities outside the frustum are skipped
• Animation Culling — entity animations outside the frustum are paused
• Nametag Cache — nametag text cached per frame (reduces string allocation)
• Dynamic FPS — minimized/unfocused window drops to ~5 FPS (~90% CPU/GPU savings)
• Hopper Throttle — empty hoppers check less frequently
• Explosion Ray Cache — explosion ray calculations cached (reduces TNT lag spikes)
• Random Tick Throttle — random ticks outside active player radius are reduced

Compatibility

Automatically detects installed mods and disables duplicate features to prevent conflicts:

• Sodium — disables conflicting render mixins; culling features remain active
• EntityCulling (tr7zw) — disables Iridium's entity/block entity culling when detected
• MoreCulling — disables Iridium's particle and block entity culling when detected
• ImmediatelyFast — disables Iridium's animation culling when detected
• Dynamic FPS (juliand665) — disables Iridium's Dynamic FPS when detected
• Lithium / FerriteCore / ModernFix — fully compatible, no conflicts

Notes

• All optimizations are optional and configurable via the ModMenu settings screen
• No visual quality is sacrificed — culling applies only outside the camera frustum
• Zero telemetry, zero network calls
