You would be surprised sometimes, at what the engineering
analysis shows for such ideas. Causing unnecessary evictions
from the cache, by GPU game activity, could slow the CPU down.
Specifically, that would be texture traffic, rather than
frame buffer traffic. Texture traffic would flush the cache
and there would be lots of misses to refill. I would not
want to guess at how it is designed.
