Sudden slow down on fullscreen.

[twotonkatrucks]

Last bit of update for anyone that still cares. I just updated to latest build, 9857, and now the games are running as smoothly as before on fullscreen. I'm not sure what changed but I had tried downgrading before (to version where I know that ran smoothly) and didn't fix the problem. Somehow this latest update did.

Thank you for all of the input. Kindly appreciated!
