# 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://guide.prismlive.com/desktop/guides/error-solution/error-information/nvidia-nvenc-support-changes-in-prism-5.0-windows.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
