Yes, React Three Fiber requires keeping per-frame logic in the render loop using refs and state stores like Zustand, rather than React state, to avoid re-render bottlenecks and maintain smooth frame rates during animations.

The best way to manage GLTF asset disposal in React Three Fiber is to apply explicit runtime cleanup patterns for geometries, materials, and textures across component structures, ensuring all loaded assets are properly disposed when components unmount or scenes change.

You can optimize Three.js rendering performance by applying instancing to reduce draw calls, constraining pixel ratio, implementing level of detail (LOD), and using texture compression to minimize GPU memory usage and rendering stalls.

Your Three.js game loop drops frames because of inefficient rendering and non-delta-based animation updates, which can be mitigated by applying delta-based updates in useFrame, instancing, and explicit GPU memory disposal to maintain consistent FPS.

Yes, this approach applies to both vanilla Three.js and React Three Fiber, providing scene graph lifecycle management, GPU memory disposal, and performance optimization techniques like instancing and texture compression across both implementation structures.
