Praise Gaben, they cry.
Valve has added a frame rate counter overlay into the client beta, so I think it’s safe to assume this will become a regular feature once fully tested in the beta.
So what does this mean? Now you’ll be able to check your FPS in-game without needing to fire up third party software like FRAPS. This’ll save your system’s resources and make checking FPS almost instant.
For the uninformed, your frame rate is an effective way of checking how well your machine is handling a game and it’s various settings.
You can opt in to the beta at any time if you want to check it out now, or wait it out for the initial, fully stable release.
