Any tips for profiling a software modeler?

Quote from suckamc

I can get some sick industrial-type sounds from Guitar RIg. It didn't occur to me to profile them until now. Any tips from anyone who's done it?

Oh, found this: Profiling software... possible? Tips? Tricks?

I had no problem profiling Amplitube, GR and Scuffham. The biggest issue I had was making sure that levels were good but not clipping anywhere. With all the ins and outs the routing got a big complicated but otherwise the sounds were great.

Like Hoth said above.. just watch out for clipping as VST operates in sometimes curious ways!
