ah yeah, that'd do it! i totally understand your point in being hesitant to fix the issue... i'd imagine changing sprite movement to being framerate dependent would cause a lot of problems with how older avatars are rigged and linked together.
it'd be nice to have the program run at 60fps (or any variable framerate) instead of the default 144fps for whatever minimal performance gains that would provide (i stream at 60fps, so any capture above that is probably overkill), but if it's more trouble than what it's worth to fix i'm totally OK with sticking to the current 144! glad this is at least a known issue either way.
thanks for the response, and thank you for all the work you've put in to make this program! it's fantastic stuff :)
