Stalling a GPU

- Remember that a shader is more like a bunch of jobs than serial GPU code, even though the syntax looks like serial code
- Avoid introducing extra dependencies between those jobs, and understand the dependencies you have as they can hint to additional optimizations
- The cost of certain operations can be completely masked by this parallelism.
- The cost of all texture samples are not the same
