Thx a lot for the hints! I’ve tried the timelines thing already, I made event tracks with ticks on bar, beat and 16th…at least I think that is what you meant? Like this:
I’ve previously just tried the below setup, which has the same type of fluctuation when previewing in viewport, looking around will inc/derease the FPS and the playback along with it,
when I set a fixed FPS in the engine’s settings, it’s more stable (when I set below 60FPS), but still can and will get affected by the game’s FPS overall…
Btw, this is a basic actor BP, in the world with a few lights to keep the position visible, but as you can see from screenshots 1 and 2, that’s a super basic setup, there’s no overhead there…
