| name | Name of the profile information used for sampling. |
| sampler | The CustomSampler that the CommandBuffer uses for sampling. |
Adds a command to begin profile sampling.
Schedules a performance profiling to begin when the command buffer execution reaches this point. This is useful for measuring CPU and GPU time spent by one or more commands in the command buffer.
A sampling started with BeginSample always has to be ended with a corresponding call to CommandBuffer.EndSample with the same name argument.
