Well, it is kind of a problem, since Reaper seems to be doing better. For the time being, it's pretty much a rather academic issue, though, simply because I will very likely not run into any CPU issues any day soon - and I'd suspect that Apple will fix it at least one day.
Oh, I am!

Fwiw... just got a new Motu M2 (needed something as portable as possible) and it's almost phenomenal regarding latency. 3.5ms RTL at 32 samples, 44.1kHz. That's RME league.
Unfortunately, they messed up their driver communication, so it's reporting just 2.5ms - which I couldn't care less about, but these wrong reports always come along with a recording offset. Which I already confirmed, all recordings are 45 samples late. I already adjusted that in Logics audio driver menu, but a decent audio interface should *not* require this (in general, you should only ever use that offset compensation when dealing with converters the interface has no idea of).
Already reported, in case Motu doesn't at least answer, I'll reach for the Gearspace megathread, I guess no interface maker likes being mentioned there for releasing unreliable drivers.
Apart from that, I will keep the M2 regardless of that, at least the offset is stable, so I just need to remember adjusting it in case I'd use another interface (I might not exactly notice, though - 1ms is like 30cm, so there...). Whatever, Motu really got their Hi-Z inputs right as it seems. Compared two DI tracks, looped beforhand, then one recorded through the Motu, one through my Line 6 HX Stomp and was then running both through Helix Native. After a tiny bit of input leveling, I couldn't tell the difference anymore. The feel when playing through the Motu is near to absolutely identical to the patches running in the hardware, too (and as I use them live and for recording since years, I know them pretty well), so that's fantastic. Btw, having a hardware modeler 1:1 compatible (minus the switching options of course) with a plugin is fantastic. And so far there's been no update fees at all (Line 6 just added a bunch of fantastic amps).
