Lowest Playback Buffer for 003r?

[ChuckS]

I currently have my 003r connected to my Mac and in PT can set the playback buffer to 32. On another PC Win 7 x86 I am using a MBox 2 and the 32 buffer setting is not available. I'm moving the 003r rig to a Win 7 x64 box and was wondering what is the lowest playback buffer available? Also, is LLM really broken? I saw that mentioned a couple of times. TIA

I run a 003 and PT9 on Windows 7 x64. I have almost zero issues, and the issue that I DO have is related to the control surface only. LLM works fine here. Lowest buffer setting in Windows will be 64. In 6 years, I have never heard a single complaint about latency at 64. The only reason I ever use LLM is if I am at 1024 for mixing and discover I need to record something quick. Then I will select LLM and turn off Delay Compensation while I record, then switch back right away to get back to mixing.
