When you’re writing shaders for use in a game or other real-time application, you also need to be able to render that visual effect fast enough that your user’s overall experience isn’t impacted. Games that fail to present new frames fast enough or do so at an inconsistent speed are said to have a “performance” problem, and shaders that take a long time for the GPU to execute are a major source of performance problems in ...
