I think we have a case of not seeing the wood from the trees.. Running benchmarks that are very simply without vsync on will really tell you very little about anything, small changes in timings per frames can make huge difference to "results". Go measure the flucuation in absolute time rather than frame rate, then you'll realize you are fretting over such a tiny about of time that it's a meanignless waste of your time. Small changes in threading or cache coherency can easily swap small time values. It does change the fact tht the results are meanignless in the greater scheme of things. Please benchmark proper amongst of geometry, state and nodes, something that can be measured in milliseconds rather than micro seconds.
