[quote name='Finbar' post='1275435' date='Jun 20 2011, 12:02 AM']If I use too many VSTs in a project on Reaper, my playback starts stuttering, which makes it hard to do much more. If I turn stuff off, then it works fine again. I'm cool with that, as I don't need everything on all the time. But is there a way of seeing which VSTs use how much CPU, so I know which ones it is most efficient to leave off etc? I use Reaper.

Have you tried using grouping stuff and/or using FX busses to reduce instances of VSTs? just a thought. You could also export tracks that you are happy with and then turn off all of the VSTs on that track, that way you could still develop a piece without having to cull plugins.
