Hi,
When I want to test as close as possible to the build perfs, I have a special layout with just the gameview, nothing else, then Playmaker Editor runs less stuff.
there are also lots of preferences for you to turn off, like "Error Checking", "Debugging", that's where you can turn off logs for example.
in the "General" prefs, you can also choose which editor windows gets disabled when playing, this also helps a lot.
Bye,
Jean
