I'm experiencing a similar issue with Metro Last Light as well. The game runs properly in Desktop Steam, but buggy and eventually crashes if loaded from Big Picture Mode.
Hello @mhess126, are you still experiencing this issue on an up to date system?
Closing as general video driver quality from 2013 is no longer relevant.
Nothing extracted yet.
Running amd HD7850 w/ latest beta catalyst. When running Portal from Big Picture, the game video never appears. I hear the "Valve tone" and then Big Picture becomes unresponsive.
When running Portal from the regular Steam UI, it loads properly.
