How to handle many updating objects efficiently in C#?

Question

I\'m developing a 2D overhead shooter game using C# and XNA. I have a class that I\'ll call \"bullet\" and need to update many of these instances every fraction of a second.

Answer 1

You are correct in assuming that by keeping the unused Bullets in a Stack prevents them from being Garbage Collected.

As for the cause of the Lag, have you tried any profiling tools? Just to find where the problem is.
