How do I check my frame rate in game?

[styphon]

I see all these threads about performance and people mentioning their FPS so I'd like to check mine and compare. Do I need an outside utility or is there some built in function to check?

There is probably a console command to display FPS (it's based on the Unreal engine, after all), but I don't think anyone knows what it is or how to enable the console in DS. Most of us are using FRAPS, which is an outside utility. www.fraps.com
