	Julien - ping for review 2015/01/05 13:11:34 It's better to measure runs/sec instead of time. T It's better to measure runs/sec instead of time. This is because we can be gated by the vsync unless we do a forced layout but more importantly we can run into time measurement issues if the test is fast enough.
