Which amp parameters are irrelevant if you're using a real power amp and cab?

With the power amp off in global settings and using a real power amp and cab, which parameters in the amp have no affect of the sound?

thanks,

Sag and possibly Depth (I think)... you can always turn Sag to 0 (zero) and it will do the same thing as the global option to turn off the power amp modeling but on a patch by patch basis.

pretty much all of the poweramp section parameters - the preamp stuff all works.
What is important is what does work - The master works as just a volume and the presence turns into a shelving filter. So depending where the master and presence is you may get a muffled, overly bright, or overly loud/quiet results if you don't pay attention to them.
