Strange I was under the impression that there are apps that make use of GS, albeit not too many.
On the perf side - I was thinking about the hardware (i.e. regardless if the driver does extra state-tracking or not) - would there be the optimisation mentioned, would there be a "stall" in the pipeline, due to the "new" values being flushed/fetched/etc. Now that I think about it, only a few of the HW guys may know the answer on this one, so don't bother with this.
