# NVIDIA NVENC Support Changes in PRISM 5.0 (Windows)

**Background**\
Starting from **PRISM Live Studio 5.0**, the OBS engine has been upgraded.\
With this update, the **NVIDIA NVENC encoder is no longer supported** on **NVIDIA Kepler GPUs** (GeForce 600 and 700 series).

In addition, the NVIDIA graphics driver must be updated to:

* **Windows:** Version **551.76** or later

If your GPU is not supported or your driver version is lower than the above, the NVIDIA encoder option will **not appear** in the PRISM settings page.

***

**How to Check Your GPU Model (Windows)**

1. Press **Windows + R**, type `dxdiag`, and press **Enter**.
2. Go to the **Display** tab and check your GPU name.

***

**How to Check and Update Your NVIDIA Driver (Windows)**

1. Right-click on the desktop and select **NVIDIA Control Panel**.
2. Go to **Help → System Information** to see your driver version.
3. Visit the official NVIDIA driver download page: <https://www.nvidia.com/drivers>
4. Download and install the latest driver (version 551.76 or later).

***

**If Your GPU Is Kepler (600/700 Series)**\
Unfortunately, you cannot use the NVENC encoder in PRISM 5.0 or later.\
We recommend:

* Using the **x264 (H.264 software)** encoder instead, or
* Upgrading to a newer NVIDIA GPU that supports NVENC.
