while looking for problems with NIR, I noticed that in the Bioshock
Infinite and also Dirt Rallye Benchmark there are times when GPU shader
utilization drops to 80% (Bioshock) or 60% (Dirt Rallye).
In Bioshock this directly associated with fps drops, in Dirt Rallye it
is not so obvious but higher utilization means higher fps.
Is this normal? Am I looking at the wrong things?
