If you’re using the same union multiple times, it may be better to stick to that, but if you’re using multiple different unions, then parts may be better.

But in general you may want to investigate to see if there’s a memory leak in any scripts also. I would say that may be more likely the issue than the graphics being poorly optimized. As far as Unions go, they definitely seem to have their issues.
