Nitrous Error: Swap Chain Present Failure:
(887a0005) The GPU device instance has been suspended. Use GetDeviceRemovedReason to determine the appropriate action.
Device Removed Reason: Device Hung: (887a0006) The GPU will not respond to more commands, most likely because of an invalid command passed by the calling application.
