Wow, MMCSS is back! : )

I guess this works best with N6 / C7, right?

Windows XP Pro SP3 under Bootcamp 2.1
Fireface 800

Everything ran fine with Driver version 3.071, but after running the 3.076 installer (which finished properly), Windows reported finding new hardware, but couldn't find the drivers.

I wound up restoring my system from a Cloned backup, so I'm back to 3.071, but I'm wondering if 3.034 wouldn't be the better option - all the benefits of the double latency buffer for higher sample rates, without all the modifications that have been made in the name of Windows 8 compatibility.

So, 3.071, 3.073 or 3.034 for XP?

The changes for W8 do not affect XP at all. So you might stay at 3.071. We tested the installer with XP, but not with a bootcamped XP with such outdated bootcamp drivers (currently 5.x). No way for us to check or reproduce that, sorry.

Anyone else seeing odd behavior with the new driver in Win 7 64 bit like I noted a few posts up?  I'd love to try out MMCSS with Cubase 7.  Not sure if it's related, but I had the earlier BSOD on shutdown problem with the older drivers.  Also often when I am in Cubase, on start up, I will get no sound going the RME, unless I pop into the RME control and toggle the buffer size back and forth.

aannnnddd.. i take that back.

I'm getting very weird "machine gun" type noises while operating my OS. It did it periodically when opening folders and clicking on the different hard drive folders. It's now doing it randomly as i operate in my OS. Probably going to rollback my driver as well.

I also got some huge ASIO buffer spikes while recording midi w/ Kontakt. They stopped when I turned off the new MMCSS option. I use Studio One... the issue is likely that Studio One doesn't support ASIO 2.3 yet (just a guess).

Anyway... i'm rolling back. Just wanted to share my findings here so far.

Hi Matthias,

I love RME and these drivers are rock solid. I'd be more than happy to help and answer any questions if it will help the next drivers.

I updated the Firewire drivers. I use the firewire connectivity instead of USB. Previous drivers were the latest drivers in the download section. I updated the firmware to the latest as well back in April, that was obvisouly done over USB.

EDIT: Let me know if I should open a support ticket instead of posting here in the forums. I wouldn't mind.

The drivers in the installer are indentical to the drivers currently available (3.073). The only difference is the MMCSS option. This one switched off - identical. So if you have a mysterious stutter with ONLY the new installer drivers even when MMCSS is switched off, then I have no clue why.
