Your choice of tile size is not directly related to the X3 panorama plugin ... I mean, the advantages and disadvantages between different tile sizes will be the same in all panorama viewers. Small tile sizes might give better "progressive" loading, but large tiles might be better for storage and might even load slightly faster (less requests). The end result is more or less the same. I am no expert, but it seems many tools default to 512 px as default, which might be a good balance.
The only reason why you might currently get better visual performance in X3 with LARGE tile size, is because it means the tile cache limit (32 x tiles) will cover much more of the view (less, but larger tiles). This is really just an "accidental" benefit, and you shouldn't really base your choice of tile size on this.
When I viewed your panoramas first time, I thought they looked great (super nice detail on zoom). I didn't notice the loading/unloading tiles until you posted the video ... Even with the previously loaded tiles re-loading into view, they will certainly load almost instantly since they are already cached in browser. My point is, I don't see a HUGE difference from the visitors perspective, who is more likely to zoom/pan to an area and then view ... Personally, while I zoom or pan a panorama, I am not really studying it because it's in motion. I will pan/zoom, then look.

Yes, it's definitely on the radar as outlined in my previous post. I would like to increase the tile cache, and see if there are any possibilities for automated progressive level preloading (pinning). It just needs to be done with proper planning.
