Does anyone know if there's a way to display framerate in F:NV? Something like a console command? I could have sworn Fallout 3 had an optional counter in the setup menu, but I'm not seeing on in F:NV.

Fraps?
Just don't record unless you want to do commentary/Game-play guides.

You used to be able to use TDT in the console (toggle debug text) and it would display a variety of information.

The command still works in New Vegas, but the text never appears.

Just use fraps, it's super easy to use

I was hoping there was one that could just be turned on, but Fraps will have to do.
