<strong>OpenGL</strong> <strong>ES</strong> 1.1 <strong>OpenGL</strong> <strong>ES</strong> <strong>2.0</strong><br />
Software Vertex Processing struggles to handle ~150K Polygons/Second with<br />
100% CPU Load while dedicated specialised hardware easily handles more<br />
than 2.3M Polygons/Second with minimal CPU load<br />
Hardware Pixel Processing using various hacks and without filtering struggles to<br />
draw 5 MPixels/Second with 100% CPU Load while dedicated specialised<br />
hardware easily handles more than 50MPixels/Second with minimal CPU load

<strong>OpenGL</strong> <strong>ES</strong> 1.1<br />

Batch API Calls CPU<br />
Consider Texture Pages, Software Transform, Etc.<br />
Use Optimisations tools and guidelines provided in SDKs<br />
culling LOD<br />
Do not submit the whole world geometry !<br />
Consider LOD variants of complex objects<br />
<strong>OpenGL</strong> <strong>ES</strong><br />
Has to implement according to specifications, no short-cuts possible<br />
Use the smallest number of lights and lowest complexity lights<br />
Consider using Per Pixel Lighting (DOT3) instead<br />
MIPMapped<br />
Use HW specific compression formats such as PVRTC<br />
Use Bilinear Filtering with Nearest MIPMapping<br />
Don’t use a 1024x1024 texture for an object 10 pixels on the screen<br />
Alpha Blending Alpha Testing<br />

Shader “Precision”<br />
Use lowp and mediump where possible<br />
Avoid using highp or mediump for all operations<br />

Texture Maps<br />
E.g. “Normalise” through a cube map rather than using maths<br />
Shader …<br />
Using 1000s of instructions for every pixel on the screen is not fast…<br />
