Warning: If you are on the fast track Windows Insider Build - the newest build breaks Overwatch. Apparently it is a bug with “raw mouse input” that causes games to have the Green Screen of Death. You will be able to start up Overwatch, but once you enter a game, it will GSOD. If you turn off raw mouse input, the GSOD goes away - however Overwatch has no option to disable it…so we are screwed until Microsoft fixes it (or uninstall Windows and revert back to regular builds).
