My understanding is there is some support for GPU-accelerated AV1 encoding in top-of-the-line latest-gen discrete GPUs that can be used for live streaming with OBS Studio 29.1 or higher. Helpful if you are in a situation where you have extra GPU and are tight on bandwidth. In my opinion it's still in the early-adopter phase though, and it's perfectly valid to use tried-and-true codecs for user-interactive rendering and encoding cases, or where the existing codec meets your requirements for the compute vs disk/bandwidth trade-off.
