Here's what we found. @flanker35 @gsuri
We have discovered that the latest update to Apple's OS Monterey 12.2, combined with further optimizations to the 650 code, under the M1 Processor, has done something to how the CPU works with the 650. It just so happened that Monterey 12.2 dropped around the same time our updates did. I wasn't seeing it on my developer build, because I have older code on that version. However, I did load a current beta version, and I was seeing some very strange things happening. Everything seemed to slow down and took its time aligning. As well as getting a sound loop on the various cockpit sounds. This all eventually righted itself after a few minutes, and Saso determined the problem was the Mac's translation through Rosetta that was doing all kinds of strange things. After some digging, Saso eventually fixed a few things, and sent me a new build. After loading, all issues were resolved.
So, expect an update in the coming days that resolves this issue.
Many apologies for this minor hiccup.
