Aiming For Best Optimization

I'm profiling a certain free function and I'm chasing around hot-spots so you would think. I'm reading into assembly and finding out a if statement to check and see If a variable is holding a valid memory address. 40% because it's being constantly called. My gui is set up in a way that the signals that have "draw" will get called in if any widget is updated. It's nice, but it's also serving as a double edge sword 😆
