13:22:28: Video Encoding: x264
13:22:28: fps: 31
13:22:28: width: 1280, height: 720
13:22:28: preset: veryfast
13:22:28: profile: main
13:22:28: keyint: 62
13:22:28: CBR: yes
13:22:28: CFR: yes
13:22:28: max bitrate: 4000
13:22:28: buffer size: 6000

Your settings are very strange. What refresh rate is your monitor running at? Chances are you should set your FPS to 30 instead of 31.

And since you're streaming to Twitch you want to set your max bitrate no higher than 3500, and set your buffer to match. This is too high. Later in the log file you set your bitrate down to 3000 but your buffer was set to 4000. Set your bitrate and buffer both to 3000.

When things stop working, set your settings to something safe that you can get to work, then once you've established what works, you can make tweaks from there. But always establish a fall-back position. Your setting a buffer higher than your bitrate isn't recommended and can cause problems in Twitch playback. In fact, use a bitrate and buffer of 2000/2000 first and see if that works.

Can you more fully describe what is lagging? Is it playback, your game, OBS, or what?

Still nothing changes same low fps , my pc specs are

+ CPU: AMD FX8320 8 CORE 3,76 GHZ
+ Video: RADEON R9 270X
+ RAM: 8GB

I think this is more than enough to stream , maybe its drivers fault ? sometimes when i play i get error message , AMD Display Drivers had stopped working

bump?

Need a better problem description.

AMD Display Drivers had stopped working

That doesn't sound good. Perhaps you should update, re-install, driver clean, whatever, such that that no longer happens.
