Then benchmark it, find out what the bottleneck is.

Again, as I said before this is a red flag, this shouldn't be
required, that fact you have it in there suggests something else amiss
with the set up of your viewer.

Brace yourself for a radical bit of programming. It's called an if statement.

MyClass:Mymethod()
{
    if (active)
    {
         // do stuff
    }
}
