20:03:18: Using custom x264 settings: "level=3.1 bframes=3 ref=1"
20:03:18: x264: frame MB size (160x68) > level limit (3600)
20:03:18: x264: DPB size (4 frames, 43520 mbs) > level limit (1 frames, 18000 mbs)

Get rid of the custom x264 settings, they're hurting and not helping. Downscale by at least 1.5 to 720p or smaller. Then your might be able to increase your preset to something like Faster instead of Very Fast.

Edit: You're running at 21:9 aspect ratio, so it won't be 1280x720, but that's ok. Just downscale it to whatever is 720 or less as the second number. Don't increase your bitrate, Twitch viewers can't download it anyways (on average). Either leave it as is or set it lower (like 2000 bitrate, 2000 buffer). Don't watch your stream on the same IP that you're sending it from.

Re Boildown and thanks So Much for You help.. Really kind of You to take time for answering my questions.

So i test last night only the change in 720p... And the stream looks much bether.. Less pixels in moove..

It was on bframes 2k or 2k5.. So what i understand i can put on 3k?
What do you mean on ref 1?
It was on very fast, you say i xan put on faster? Bith if i had a message warning on CPU?
How do you watch your stream to know if quality is ok if you can t watch it from same IP?

Take care, look forward for yoir answers and once again thanks a lot!

Go to Settings > Advanced > Video > Custom x264 Encoder Settings, and delete everything in the text field there.

I made that recommendation based on your previous log file. Try them both. Do five minute or longer sessions of high action gameplay and post a new OBS log file showing those sessions and I'll re-examine the performance.

From the most recent log file:

20:18:58: Using custom x264 settings: "level=3.1 bframes=3 ref=1"
20:18:58: x264: frame MB size (160x68) > level limit (3600)
20:18:58: x264: DPB size (4 frames, 43520 mbs) > level limit (1 frames, 18000 mbs)
20:18:58: x264: MB rate (326400) > level limit (108000)
20:18:58: ------------------------------------------
20:18:58: Video Encoding: x264
20:18:58: fps: 30
20:18:58: width: 2560, height: 1080

"level=3.1 bframes=3 ref=1" is still there which means you didn't remove it. Remove it.

"width: 2560, height: 1080" you still need to downscale more. You can't stream 2560x1080 at 2500kbps, it just won't work. Downscale to 720p (at least). This is why the performance is bad.

It should be close to good now. Try turning Aero on. Just noticed its off.

Duplicated frames is at 1.02% for a nice long stream... that's just a little high IMO, but you could check the VOD and see if it bothers you or not.

If it does and turning Aero on doesn't fix things, try using one step smaller resolution. Whatever is next below 720p.
