Will "bullet impact Marks" have a significant effect on performance if you don't make them disappear?

Hoping this is the right section.

For immersion, I’d like to have the marks your bullets make when you shoot an object stay until the “level” is completed (they currently disappear after a few seconds). Would this have a significant effect on performance?

For the sake of context, let’s say there’s 50 players, all shooting things, for an hour.
