No, not particularly - I was just looking at INTEL_DEBUG=state when running 
Shadowrun and noticed a bunch of GS and URB churn in an application that 
purely uses ARB programs.  Seemed strange.  With the patch, GS remained 

A couple quick tests doesn't show much gain from the change.  But it does 
simplify the code a bit, at least.
