GPUcraft
Client-side rendering optimization mod for Fabric that eliminates CPU draw overhead and stabilizes framerates in entity-heavy scenes.
Key Features
- Vulkan-Style State Caching: Skips redundant OpenGL driver state switches (
glBindTexture,glDepthMask,glBlendFunc), cutting CPU-to-GPU overhead. - Occlusion Culling: Fast raycast culling with zero per-frame heap allocations; stops rendering mobs hidden behind solid blocks.
- Frustum Culling: Bypasses rendering for entities outside the camera view cone.
- Distance Limits: Independent render distance limits for entities and block entities (chests, signs, banners).
- Particle & Drop Budgets: Caps spawned particles and dropped items to prevent freezes during explosions and mob farm operations.
- Weather Toggle: Option to disable rain/snow rendering to save GPU fillrate.
- FPS Throttling: Configurable in-game FPS cap and background throttling when unfocused.
- Live Diagnostics HUD: Real-time FPS, active GPU, and culling statistics.
