Mobile XR presents unique shader optimization challenges. With the need to render two views at high frame rates, shader performance becomes critical.
XR-Specific Challenges
Mobile XR devices must maintain 72-120fps to prevent motion sickness, leaving very little budget for shader complexity.
Optimization Techniques
Single Pass Stereo
Use single pass stereo rendering to calculate lighting and effects once for both eyes.
Simplified Lighting
Reduce the number of lights and use baked lighting where possible.
Mobile-Friendly Shaders
Avoid expensive operations like dynamic branching and use mobile-optimized texture formats.
