![]() ![]() As even older versions of NVENC have long been able to record at 1080p, this change primarily appears to be NVIDIA increasing their limits now that these services are better able to handle the high bitrates that go with 1080p streaming. Furthermore the broadcast module can now upload video streams at 1080p60 with a maximum bitrate of 9Mbps, supplanting the module’s previous 720p60 limit. First launched with Twitch support back in late 2013, the broadcast module is now gaining support for Google’s rival YouTube Live service as well, allowing GeForce users to broadcast to the service of their choice. Moving on, similar to GameStream, GeForce Experience’s video broadcasting module is also getting new functionality and an image quality boost. And on a technical side note, though not specified in NVIDIA’s presentation, as 4K support is limited to SHIELD Android TV I’m curious whether NVIDIA is still using H.264 or if they’re switched to HEVC, as Maxwell 2 and SHIELD Android TV support hardware HEVC encoding and decoding respectively. Meanwhile on the reception side, a SHIELD Android TV is needed to receive 4K video, and NVIDIA is recommending a hardwired 100Mbps (or better) Ethernet connection for best performance. On the encode side only the newest Maxwell 2 generation GPUs have an NVENC unit capable of encoding at 4Kp60, so high-end Kepler users won’t see this functionality. At the same time because of the step up in quality the system requirements to use the new 4K mode are significantly higher as well. Until this latest release GeForce Experience had been limited to serving up GameStream with 1080p video and stereo audio, so this marks a significant increase in GameStream’s video and audio quality. ![]() Furthermore NVIDIA is also giving GameStream the ability to serve up 5.1 audio. With the SHIELD Android TV capable of decoding 4K video content, NVIDA is now giving GameStream the ability to encode video at that resolution, allowing for GameStream remote gaming at full native resolution for 4K TVs. On the GameStream front NVIDIA will be offering new functionality specifically targeted at the recently launched SHIELD Android TV set top box. To kick things off, in a new beta release hitting NVIDIA’s servers today, NVIDIA will be updating several of GeForce Experience’s various NVENC-powered features to enable new features. As one might expect, NVIDIA is not stopping there, and in a briefing to the press this week, NVIDIA is announcing some of their feature development plans for GeForce Experience over the next couple of months. Along with its software update and game settings optimization features, NVIDIA has added a number of features over the past couple of years tied to their NVENC hardware encoder, including GameStream, ShadowPlay, and most recently the beta for Share and GameStream Co-Op. Since launching their GeForce Experience software utility over two years ago, NVIDIA has continued to iterate on it in a fairly regular fashion. ![]()
