Message : Retool perf test running. This change does a few things involving the way we run the perf tests: - Perf test runner can capture different metrics Useful for capturing the new "nanoSecPerIteration" metric. - Removes the "score" metric We'll move to the new time-based metrics. These new metrics are scaled correctly with iteration counts. - Runs three trials per perf test This gives more measurements per test. Each trial is approximately one second. First the perf tests set a fixed number of iterations after calibrating the number of steps that we can run in one second. After that the three trials are run. This should give more stable results. - Apply more CPU stabilization on Windows Use SetPriorityClass to apply more CPU priority. Also upgrade SetThreadPriority to the highest level. - Always build the Vulkan command buffer test This catches build regressions more easily. We still skip the test on non-Android platforms.
