The audio and GUI processing are happening on different threads (that is, in practice on modern systems on different CPU cores), so at least in principle a high load on the RT audio thread shouldn't be affecting the GUI that much. (Unless the audio processing also uses many threads/CPU cores, which could be possible with something like Kontakt.)

There may be things like plugins waiting in the audio thread for the GUI to update, which would be a horrible programming mistake of the plugin developer. Reaper wouldn't be able to do much, if anything, in that case to improve things.
