New Thunderbolt Drivers for MOTU

Was just checking and the MOTU website just announced a beta release of the new Windows Thunderbolt ASIO drivers for the AVB family and a rewrite of the USB driver as well.   This will be interesting over the next few days.  Beta - blessing or curse...   We will see.
 
Take care

UPDATE:
In case anyone's interested - you *can* downgrade the firmware. I just installed the 1.2.5 again, like it was an "update" and it worked fine. Then I uninstalled the new driver and installed the old one (1.6) and everything works fine ;-)
 
I don't think that taking away our ability to set the "hidden" buffers is progress
 

The new windows drivers let you go way down to 24 or 16 samples - but that's no good if your PC can't cope.
 
I might be able to play around with BIOS settings or something (God knows I've tried everything I can think of in Windows) to get my PC to "paly" with 64 sample buffers - but it's easier to just go with 128 samples and the "minimum latency" setting (the lowest of the "USB Streaming Mode" settings)
 
I raised a ticket with them - so we'll see what tMOTU say. It *is* a beta driver...

There are some new drivers and firmware and now you can change buffer size AND "Host Safety Offset".
No more control panel - it's all changed in the web interface.
Both buffer size and host safety offset go down to 8 samples! This shows up as 0.7ms RTL (!) in SONAR - and is, of course, unusable - for me anyway.
 
I'm not really able to get lower latencies with this driver - but between the two settings, you can make changes in much smaller increments, so it might help everyone get settings that are "just right".
 
I also think that maybe some combinations might be better than others (eg is it better to set lower buffer settings and higher offset, or higher buffer size and lower offset? you could achieve the same latency with various combinations like this). My PC just does not like buffer size of 64 samples. The ampsim channels just go berserk and seem to self oscillate - in to the red!
 
So the new beta driver is much more configurable than the last one. We're on the right track now.
Maybe at some point we can get to gether and work out optimal combinations of settings - but it may vary for everybody's PC and what they're using in SONAR etc.
