I'm also wondering what would be the advantages of using a coiterator...?
As an experiment, I tried switching to using a coiterator. I got a 30% increase in framerate!
My code now looks like this:
class RendererIterator: # used if usingCoiterator is True
def __iter__(self):
return self
def next(self):
ogre.WindowEventUtilities.messagePump()
root.renderOneFrame()
from twisted.internet.task import coiterate
renderSystem._initRenderTargets()
root.clearEventTimes()
coiterate(RendererIterator())
reactor.run()
