WebGL Performance Optimization for Modern Portfolio Sites
Rich, interactive 3D experiences are becoming the standard for premium agency websites. However, rendering complex WebGL scenes on mobile devices presents significant performance challenges.

Geometry Instancing
Instead of drawing 10,000 separate objects, geometry instancing allows us to draw a single geometry 10,000 times with a single draw call, drastically reducing CPU overhead.
Texture Compression
We utilize KTX2 and Basis Universal formats to keep texture footprints small in GPU memory, allowing for high-resolution assets that load instantly.
Frustum Culling and LOD
If it's not on screen, don't render it. Combining frustum culling with Level of Detail (LOD) models ensures we only spend GPU cycles where the user is looking.
