Best Frame Rate setting for Live VJ tool in UE 5.1

Hey all,

A VJ tool I produced to be used live via OSC, streamed over Spout and rendered in UE, is currently set to “used fixed frame rate” at 30fps.
As most VJs work with a minimum of 30FPS, I assumed it’s the best way to achieve maximum performance, as anything higher than 30FPS is not needed and will waste resources.

However, I suspect now maybe smooth frame rate is better cost-wise?

Any tips on that?

Thanks a lot
