The settings has been ON since I introduced the option to serialize the draw dispatch. Just before the 2.6 release I did testing at my end and still found serializing the draw dispatch to be far more effiecent on my Linux/NVidia drivers so I left the option on. In the original thread when I introduced the optional draw mutex into the draw dispatch I did call for testing on the performance impact but I didn't get sufficient feedback to make a more informed decision than just basing it on my own testing. I would still appreciate more testing, as I'd expect that best default setting to vary on different hardware and drivers - I for one would love to see better scalability in driver/hardware.
