I have seen it done both ways.
A person declares a convar.... declares a float, hooks the convar change to set the float.

I'm looking at damage multipliers in a damage hook, now this callback may get called often, but is there any actual performance difference if I choose this route vs GetConVarFloat every time the callback is fired?

Thanks,

Mark.

I asked this same thing and was told it's minimal

In the grand scheme of things, the performance cost is negligible. However, you will probably want to consider how you're using it.

If you're calling it per-frame, chances are you're likely doing more expensive operations in that hook and you'd want to profile your code before you make a decision to turn your GetConVar* into a global variable.

In short: write beautiful maintainable code first, profile and trim the low hanging fruit second.
