From the examples above the only really signifikant drop in speed with "none" that might let me choose one of the other modes was "caffeine with mep", also at higher zoom rates. Even with middle sized protein structures like '4otb' "none" was still preferable. And although rotation speed was much higher it seemed to take slightly longer from click-start to drag-end until the full view was restored at the end. This delay after releasing the mouse button before the full view was restored was almost not noticeable with smaller models. To make the differences between the modes more testable on faster systems a larger (resizable?) display would be good. > Q: Is this a viable solution to the iPad poor-performance problem? > No iPad available. > Q: Which would you recommend for the default behavior for JSmol? > Not sure yet. > Q: Suggestions? > 1) Would it be possible to determine or estimate the frame rate and/or mouse speed to use it for an additional "auto" mode? Without any information on the system speed an estimation purely by atom number, view type, display size etc. would probably not be sufficient. 2) It would be nice if the full view could be restored already after the movement stopped and not only after release of the mouse button.
