WebGL Audit

Review WebGL implementation for compatibility, performance, and best practices.

Audit Checklist

Compatibility

• WebGL context creation handles failure
• Context loss recovery implemented
• Required extensions checked before use
• WebGL2 with WebGL1 fallback (if needed)
• Shader precision qualifiers appropriate

Performance

• Draw calls per frame reasonable (< 200 ideal)
• State changes minimized
• Textures are power-of-two or handled
• No synchronous API calls in render loop
• Geometry batched appropriately

Memory

• Texture memory budget defined
• Unused resources cleaned up
• No texture leaks
• Buffer reuse where possible
