I'm implying that the use of Unity is not an issue since it's consistently used during all the benchmarks. So the (relative) numbers are accurate. If a benchmark is faster with Unity, it will highly likely also be without it. I'm was stating that argueing about is kind of nonsense. Unity is not the only factor influencing video performance.
Furthermore, if it would then that would indicate a buggy driver and that the hypothetical inconsistent results cannot be blamed by wrongdoing of Unity.
