FetchUnitBusyThe percentage of GPUTime the Fetch unit is active. This is measured with all extra fetches and any cache or memory effects taken into account.
FetchUnitStalledThe percentage of GPUTime the Fetch unit is stalled. Try reducing the number of fetches or reducing the amount per fetch if possible.
WriteUnitStalledThe percentage of GPUTime Write unit is stalled.


what means 'fetch unit'?  can not find it in archetecture overview.

and how does profiler calculates this values? Take average pertangles for all fetch units?

And when write\fetch unit gets stalled?

thanks for answers
