I am having an interesting time getting ideas to solve my crackles and glitch problem (actually I think the HD is getting too stuffed and defraged), and so I discover this ancient thread. Feeling like a PlanetZ archeologist here

What are these wild allogations; XTC-mode sounding snappier than SFP-mode, and with the same ASIO-drivers?
Actually, the "more-GUI-needs-more-CPU" argument is to some idea valid and kind of makes me contemplate going back to XTC (I've gone SFP -> XTC -> SFP).
SFP works pretty well together with REAPERS ReaInsert plug-in. It's like running XTC-mode, but with 100% routing.
Anyway, what is peoples views on this today? Doesn XTC-mode sound better than SFP-mode? And if so, why would it?
Technically, I have always envisioned loading an XTC-plug-in like in your favourite VST-host as hooking up an ideal I/O-stage between the floating point engines of most DAW-software and the 32-bit integer engine of our hardware.
Exaclty like an ASIO1-source/ASIO1-dest connection should be in SFP-mode.
But maybe there is something else to this paradigm?
Could the added GUI of SFP.exe cause jitter or any other digital degrading effect?
Just throwing oranges here.
