What is NVidia NVENC?
NVENC is NVidia’s hardware video encoder which is integrated into NVidia discrete GPU’s.
This encoder will take the role of encoding your stream from your CPU and use your discrete NVidia graphics card instead. NVidia’s NVENC was introduced with the NVidia GeForce GTX 600 series graphics cards in March 2012.
How do I enable NVidia NVENC?
If the option for NVENC is not enabled in the Twitch app, please make sure that you have the following:
- An NVidia GeForce GTX 600 series or higher graphics card (check the next section for a guide).
- Have up to date drivers. Please check here if your drivers are up to date.
It provides you with a full explanation and directs to the Nvidia Wikipedia page with exact GPU specs.
Disabled NVIDIA device or unsupported/old
Make sure your device is enabled through the device manager
or select a different encoder from our settings.
This error message is received when your driver for the selected encoder is out of date.
If you are using one of the hardware based encoders please update your drivers accordingly.

If you do not want to update your drivers, or do not have the time, you can always swap to the H.264 software encoder to record at any time (note that this may affect your recording quality).
Please help us solve this issue by contacting our support: Overwolf Support.
Please consider changing the encoder via the Overwolf Capture Settings page:
- Open the Overwolf settings menu
- Navigate to the “Capture” settings
- Under “Encoding”
- Select a different encoder
- Quick Sync > NVIDIA
- Choose x264 if you don’t have any of the above
