How to increase R3F project performance?

1. Reduce Draw Calls
Problem: Too many objects/materials in the scene can hammer the GPU.
Solution:

Merge Geometries: Combine static meshes (e.g., using three.js BufferGeometryUtils.mergeBufferGeometries). This reduces the number of draw calls.
Instancing: Use InstancedMesh if you have repeating objects (like trees or rocks).

2. Optimize Materials and Textures
Problem: Shaders, large textures, and transparency can be heavy on the GPU.
Solutions:

Use THREE.MeshBasicMaterial: For non-dynamic objects without lighting needs, skip the shader-heavy MeshStandardMaterial.
Compress Textures: Use .ktx2 or .basis textures with THREE.KTX2Loader for GPU-friendly compression. Alternatively, tools like squoosh can help.
Use Lower Texture Resolutions: Ask yourself, does that 4K texture really need to be 4K? (Spoiler: It probably doesn’t.)

3. Culling & Frustum Management
Problem: Rendering objects the user can’t see is a waste of resources.
Solutions:

Frustum Culling: R3F automatically culls objects outside the camera's view, but ensure objects’ frustumCulled is true.
LOD (Level of Detail): Use lower-poly versions of far-away objects.
