Now that I (and others) have uninstalled and reinstalled FSX to get SP1 installed, we obviously lost all of our previous tweaks. As I understand it, some old tweaks are no longer needed and new ones posted by Phil are there for us to play with.What other tweaks should we put back in to get more out of a great release?

In the process of trying to research this...I know that the FIBER_FRAME_TIME_FRACTION one does not apply to multi-core systems now due to all the new threading stuff that places that functionality on its own core. Still works for single core machines though apparently.As far as the other tweaks like autogen density, bufferpools etc, I think it's gonna take some time to get answers on whether or not those are still valid.
