WebGL optimization in Three.js involves profiling performance bottlenecks, then applying targeted fixes like adaptive rendering, geometry batching, and texture compression. Measure FPS and frame times first, apply optimizations, and validate gains against your target frame rate while preserving visual quality.

Collect FPS, frame times, and GPU/CPU metrics to identify bottlenecks. Use browser DevTools and profiling data to guide which optimizations—LOD, culling, shader tuning—will have the most impact on your specific scene.

Yes, using adaptive rendering techniques like dynamic device pixel ratio scaling, frustum culling, and level-of-detail systems lets you sustain target framerates across desktop and mobile. Profile your scene first to find the right balance.

Key techniques include geometry batching to reduce draw calls, texture atlasing and compression, shader optimization, and frustum culling to skip off-screen objects. Apply these after profiling identifies GPU as the constraint.

Implement safe fallbacks for non-WebGL environments that gracefully degrade functionality while maintaining usability. The skill covers fallback strategies alongside adaptive rendering across diverse device capabilities.

Device variance stems from GPU power, memory, and CPU differences. Adaptive rendering—LOD, dynamic resolution scaling, and culling—lets you detect device capability and adjust rendering load to maintain consistent target framerates.
