Twitch and NVIDIA are excited to announce that as of today you can download and stream to Twitch directly through GeForce Experience. What’s more, this is the first integration that utilizes NVIDIA’s proprietary video encoder. This translates to outstanding video quality, and thanks to the H.264 hardware encoder built into Kepler-based GeForce GTX GPUs, you can stream without having to worry about CPU performance hits.

Seeing as this is a beta release, NVIDIA will continue to add additional functionality based on user feedback. The next major milestone is to add desktop capture for ShadowPlay and better microphone control.
