Performance Question: Visibility

I had an idea that if i lump every object into a single group and then have an event that read
+Group Generic 1 is outside of frame
-make invisible

+Group Generic 1 is inside of frame
-make visible

Would this speed up performance at all?
Its hard for me to test because I have a good computer.

Thanks!

It wouldn't do anything. The rendering code doesn't draw what's outside of the window area.
