Question / Help choppy video on preview stream

10:50:17: Total frames encoded: 398, total frames duplicated: 45 (11.31%) 10:50:17: Total frames rendered: 416, number of late frames: 7 (1.68%) (it's okay for some frames to be late)

Well that's pretty crappy performance, over 11% duplicated frames. Granted it was only a 14 second encode. Try a five minute encode and see if it levels out. Yeah you said only a problem in the preview screen but I don't think OBS logs the preview screen so I really can't judge that.
 
Yup, 13% duplicated frames. Your bitrate is unreasonably low however for such a high resolution. Try cranking up the bitrate to 10,000 or 20,000 kb/s and see if it improves. Your CPU is excellent for encoding so I don't see why that would be it. Also, and especially since you're using Windows 10, make sure your GPU drivers are up to date.
 
I cranked it up to 20,000 kb/s. Looking better on the preview stream but not as smooth as the game itself. I also started it streaming to twitch and when watching my twitch feed it stutters quite a bit and then hangs like I don't have enough bandwidth. My upload speed right now according to speedtest.net is 27.68 Mbps

I'm on the latest video card drivers.

I just loaded up wildstar and got very different results. Much better! I wish the stream looked better but it's working better on wildstar than it did on warcraft.

you shouldn't be watching while you encode. and you cannot stream @ 20,000 bitrate @Boildown probably thought you were local recording. lowewr your bitrate to 2500 at max for that resolution. It seems like your GPU is having trouble downscaling since most of the excess time is spent on the video conversion.

try lowering you ingame and base resolution in OBS to 1080p and scale down from there. I bet things start to work a lot better.
 
Setting in game resolution to 1920x1080 stretches it across my monitor and it looks horrible. But I tried it and set OBS to 1920x1080 but OBS only shows part of the image.
The native resolution of my monitor is 3440x1440.

Typically I play WoW in windowed, full screen, so I can easily do stuff in my 2nd monitor while the game is running. This seems to be the issue. When I set wow to fullscreen the performance of the game capture improved dramatically.

Now, what to do about this odd resolution while streaming to twitch? I want something that looks good to viewers but doesn't stretch the image.

Well for streaming you have to choose something that will look acceptable at the bitrates you can send to Twitch, at a resolution that looks ok to viewers. I think 720p at 21:9 aspect ratio is just too much, try a smaller downscale.

viewing on twitch will look best at 16:9 aspect ratio. if you run in windowed mode, set your window to 1920x1080 then obs to the same base resolution.

I disagree, he's better off with letterboxing than a distorted aspect ratio.

Well I guess he could use a 21:9 ratio with a 1080p base @archer75 can you try to do a resolution like 2520x1080 in your games and in OBS base?

I believe its just the 1440p wide downscaled to 720 wide that is causing the issue.
