I never understand how something so “irrelevant” brings so much attention. use FixedDeltaTime in fixed update and deltaTime in the update, or simply use deltaTime always, thats all, there is no “better” option, just make sure that if you use fixedDeltaTime is from inside fixedupdate or use allways deltaTime for keeping it simple
