Twitch Stream only arrives in 720p60 instead of 1080p60?

I've been streaming on Twitch for some time. I'm streaming to 1080p60. I also have a good PC and a reasonable management, so that is not a problem.

For some time, however, my stream has only been available live at 720p60 and no longer at 1080p60, although I'm streaming over Streamlabs OBS 1080p60. The repetition can strangely be watched in 1080p60 after the stream.

Other streamers, including those I know, who also stream without afilliate, can transmit their stream in 1080p60 without any problems. Only with me it is not possible.

What can that be? Twitch support only replies to me with automatic messages and does not help me: /

Twitch down regulates due to the increased data traffic by Corona

Other streamers, among others also known streams from me but without problems in 1080p60 and there it is available. Only not with me

From 720 to 1080 there's now no world-changing difference. Unfortunately I can't offer you any more information ^^

Unfortunately. The picture quality is much worse at 720p when streaming Warzone than at 1080p. I see that extremely in the repetition. That's why it annoys me so…

and it works for others too

Warzone also looks terrible for me at 1080p60, so when I watch. If I play it myself then great but in the stream. No

Yes, because the game draws extremely bitate. That is why it is all the more important that the stream can be called up to 1080p60, because the picture looks really ok there for me, but in 720p 60 even my facecam is pixelated…

Unfortunately I don't know anything about streaming. But as long as you haven't changed anything, difficult.
