This the StarCon bug with NVIDIA GPUs, theres a log thread on it. Basically you can look in the error log to confirm if you have the Swap Chain errors.
Heres the thread and here's what the error looks like.
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.
Hope its not impacting you too but if so, might want to +1 that thread and keep an eye out there for updates.
