Timers are affected by processor speed?

I guess my only solution is to try to streamline my game (but it has no for-each-object events and very few and small pictures) or just forget about it.

Effects can take a toll too.

You can also run it through the debugger, and use the analyser to get an idea of where most of the processing is taking place. The analyser will also break it down to event groups, so using a few of these helps narrow it down when indentifying the bottle necks.
