Commen= t # 14 on bug 95474<= /a> from Marek Ol=C5=A1=C3=A1k 
I've done some profiling.

Bioshock Infinite:
- the game is CPU-bound most of the time
- some small performance enhancements have landed already
- the FenceSync optimization is a work in progress, expect a 30% improvement
- most of the scratch buffer usage is for private memory, not VGPR spilling
(this may be a defect in our indirect indexing)
- if I'm not taking private memory usage into account, it's still in top 2 =
of
the worst VGPR spilling apps

DiRT Showdown:
- the game is GPU-bound
- there are a bunch of very slow pixel shaders using while loops, it's uncl=
ear
how to make them faster
- most of the scratch buffer usage is for VGPR spilling
- it's in top 2 of the worst VGPR spilling apps
