Another thread was opened on the Fractal forum regarding this issue - it has now been locked, not sure why it was all very courteous.
"We are of course aware of the USB latency reporting complaint. We understand and empathize that this issue and required workarounds have made things more difficult for some of you. However, the FM3 team has been dedicated to keeping up with Axe-Fx updates for as far back as I can remember. It requires a lot more work for the "little brother" to inherit features from the powerful Axe-Fx III, and addressing the USB fix is would need to take effort away from these other areas. The vast majority of customers would prefer that we continue to add new amp models, new effects, new sound features, and more -- and even clamor on a regular basis for these to be done already. And this isn't like "dusting crops": the FM3 is a serious professional product which needs to be programmed and maintained with the utmost care. We will keep you updated on any developments in this area and maintain our commitment to high quality products"
