...AMC 14 in a medium sized theater that didn't look to be a wrap around:
IMAX 3D was particularly well synchronized, very bright and crystal clear. Resolution was eye popping at ~50' from screen. Sound: good. Could detect some shuddering when movements were too fast for the system's capability (give them 5 years).
Seated at center, my field of view was truncated (framed) not only by the 3D glasses, but the relative narrowness of the smaller venue (~500 capacity?). The smaller venue may have been intentional for optimal brightness and optical trueness (just as a long/narrow focal length keeps a deeper field within focus.
(We have a HUGE original "wraparound" IMAX in the city, but as I recall its image was generally about the same - iirc.)
Ymmv.

...Like digital artifacts when action rate is greater than the sampling rate can handle? I haven't noticed this at the local mall IMAX (also AMC) although this is a recent addition to the cineplex so it may have a later version of the equipment. It's also a larger auditorium @~800 seats.
The one improvement I have noticed with the digital presentation in general is a total lack of the image jumping around on the screen as each film frame is located slightly differently in the gate than the one before and after. Used to drive me crazy and I never could completely ignore it. Now I don't have to! What's the name for this phenomenon?
Yes, like you describe as "image jumping". Term might be "strobing"?Caught it for a moment in a scene Vickers was in. I expect, like with standard film, the more digital "snapshots" per second the better. If/when they get up to 1000/sec (guessing) we'll be talking "holographic realism". Till then, they will remain motion limited.
Saw something similar like a set "wiggle" (ship's hangar/loading dock) in Aliens just before the squad briefing. That was attributable to a foreground matte painting being jostled momentarily (camera dolly?) that didn't jive with the real sound stage.
(Just picking nits.)
3D must be SO much more difficult to synchronize.
