Shader Performance Optimization - UE4 Materials 101 - Episode 7

This video discusses ways to measure the performance of your shader and then optimize it so that it runs faster on the GPU. Performance measurement methods include using the built-in Shader Complexity View in Unreal's viewport, checking the shader's instruction count, and measureing the actual framerate or GPU milisecond timing that it takes to render your shader. Once you know your shader's performance, you can optimize it in several ways - including removing unused parts of the shader, refactoring math formulas, combining single channel data together for performing math on multiple channels in a single operation, and packing texture maps together into a single texture to reduce texture sampling.
