I'm a bit nervous about whitelisting games without checking frametime variance. From experience with certain game patterns, threading can introduce stuttering in certain apps and cause the general experience to feel worse even though the general throughput appears to go up, as reported by benchmarks/etc. Not that I have a great solution, other than advising that anyone testing this and submitting results should be on the lookout for micro-stuttering or extra hitches.
