Collisions - performance question

Does it have any impact on performance to turn off collisions on sprites, which for instance is part of the UI (assuming no collisions ever happen anyway).

Just asking to decide whether I should use time on turning collision etection off, on sprites which doesn't need it.

Cheers,

No, collision is only checked when you check it. So turning off collisions if you never check it won't have a performance impact.

Thanks for the answer!
