A subtle update to the Steam Client beta has added a long-requested framerate counter to Steam Overlay. It rolled out yesterday.
PC gamers are rejoicing in the comments underneath the update notes. They had been requesting this for some time, and had to use a tool like FRAPS if they wanted to check their game's framerate. Of course, many now are asking for the FPS counter to be customizable in both color and display position, but just having one is a plus.
The FPS counter was added in with other features as of yesterday. The client beta update adds several fixes and adjustments to its broadcasting features, and a few fixes and optimizations elsewhere. See the full list at the link.
