Which game, or games, are you unable to record?
@Wasntafairfight - That's interesting, there really shouldn't be a difference between the 2. I can't seem to track it with our back-end tools, but does it state which version of Raptr you are using when you right-click the icon and select Help > About Raptr?
Try to reinstall Raptr (you can save your settings in %appdata%\Raptr\Raptr.cfg and copy it back after installing Raptr again) and check GVR after installing raptr.
I have mentioned, that in some games GVR and overlay works once - only at 1st Raptr launch.
@deadlymercury - Thanks for making the ticket. I'll have QA check on that to see what the cause might be. I do know that "IL-2 Sturmovik: BoS" does not have in-game overlay enabled, while Rise of Flight (depending on which version you have) is enabled.
