Try out the following five fixes to resolve your NVENC issues.

Restart your PC

One of the first things you should do is restart your PC to free up any tied GPU resources that might be slowing the process down. Also, if you’re getting error messages indicating that you have too many concurrent sessions running, keep in mind that consumer GPUs can only handle three NVENC sessions at once, meaning a restart is important to free up GPU resources. 


Update your GPU driver

Using the device manager allows you to keep an eye on all drivers to any peripheral on your PC. Here’s how you can update your Nvidia GPU drivers. 

Step 1: Right-click Start and select Device Manager from the menu.

Save your changes and OBS should work fine now. 


Lower your resolution

H.264 can support up to 4K resolutions while H.265 supports up to 8K. The problem is that most streaming services don’t support H.265 yet. This means that if you’re using H.264, you need to limit your resolution to 4K or below based on your PC’s hardware. 


Switch to software encoding

If you can’t resolve the error no matter what, switching to software encoding can fix the problem. Here’s how.

Step 1: Open OBS, click on File followed by Settings.
