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.

Controls

• F9: Toggle Diagnostics HUD
• F10: Cycle Presets (Quality → Balanced → Performance)

(Customizable via Mod Menu or vanilla Controls settings)
