Steam overlay on non-steam games

[Scaramanga]

Hi, I would like to have the option to use steam overlay on non-steam games like we do in windows. I am not able to alt-tab from some games (e.g. torchlight) to talk to friends. Cheers.

If you run non-steam games through steam, you will get the overlay. Exceptions are 64bit binaries and games with weird rendering loops.
