Tested on the factory preset AC-20 Deluxe (~70% CPU usage because of "ultra-high" reverb, 60% with "eco"). Scene "Trem", engaging Drive using the switch. It takes 8 (eight) second for FM3-Edit to display that DRV is on. It's the longest I've seen so far
Any suggestions?...
UPD. Switched between scenes and views for some time, switched between Reverb quality settings - now the changes is displayed within a couple of seconds, as it was before
BUT if I turn on amp boost and/or saturation switch, time to display the change in DRV takes 4 seconds!
