I am finding the same. Streaming to Twitch produces a video similar to that of 720p. From what I can tell, Twitch pumps out 1080p - unless you become a partner and then they present your viewers with an option to scale it down. My internet is certainly fast enough to stream in HD and so I too am wondering if I am doing it wrong.

It's important to keep in mind that (afaik) Shadowplay outputs at whatever resolution and framerate your source is. The encoder is good but it's no miracle worker and 3.5 megabit simply isn't enough bitrate to produce an extremely high-quality image for a grainy, high-motion game like GTA4 in 1080p 60fps. In my opinion, for the purposes of livestreaming I think your example looks fine.

This, of course, was in the wake of them putting a hard cap of some sort in place. YouTube on the other hand recommends double that for 1080p. What is more baffling is that the output video in my link does not even look like it is 60fps. It is more in-line with YouTube's ~30. On top of that, the quality feels worse than using OBS OpenGL & CPU Fast mode. If anything the quality is just as bad as Intel's Quick Sync option in either Xsplit or OBS. Am I the only one that feels this way? Perhaps if I saw someone else's video @ 60fps I would feel as if I made a mistake instead of it being a Shadowplay related issue.

I aproached teh same issue in another thread a few days ago, but now i have proofs. Im not a twitch partner nor i have followers in there, but i still like to make my streams every once in a while to demoshow games to friends of mine, with that said lets go to the proofs itself. I made a stream with OBS and exported the recording to youtube thru their standard option that everyone have at their disposal, and the video on youtube got 1080p wich is the res i was playing at http://youtu.be/wgh6OZVzuMk U can check description to be sure it came from Twitch When i stream with Shadowplay and export it to youtube, it only gets 720p http://youtu.be/Qv3XrUg8jpw Again, check description to make sure, i have 1h.30mins of stream on this specific video on twitch.. Both were being playd in 1080p and stream on High, on OBS i cap teh bitrate to 3500kb/s wich is the highest twitch allows (oficially) TL:DR Shadowplay is streaming in 720p even if its being played in 1080p. proofs above
