| // - Static/Multiple/Dynamic vertex buffers: Tests switching buffer bindings. This has |
| // a state tracking cost as well as a GPU driver cost. |
| // - Static/Multiple/Dynamic bind groups: Same rationale as vertex buffers |
| // - Static/Dynamic pipelines: In addition to a change to GPU state, changing the pipeline |
| // layout incurs additional state tracking costs in Dawn. |
| // - With/Without render bundles: All of the above can have lower validation costs if |
| // precomputed in a render bundle. |
| // - Static/Dynamic data: Updating data for each draw is a common use case. It also tests |
| // the efficiency of resource transitions. |
