NVidia NVENC

What is NVidia NVENC?

NVENC is NVidia’s hardware video encoder which is integrated into NVidia discrete GPU’s.
This encoder will take the job 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 you have the following:

  1. An NVidia GeForce GTX 600 series or higher graphics card (check the next section for a guide).
  2. Have up to date drivers. Please check here if your drivers are up to date.
If you do not own a GTX GeForce 600 series or above graphics card, this encoder will not be available to you.
