Question / Help Stream lag/stutter when gaming over 60FPS

[jlw_4049]

Internet speed is 240MEG down and 25MEG up. I wanted to do a little streaming buuuut I'm getting stutters when utilizing my gaming monitor.

So, I have an i7 6700k, gtx 980, 16gb ram for my gaming pc. Everything is stock/not overclocked. When I'm streaming, I down scale to 720p 60 fps. (I have tried 30 fps, all the encoders, different bitrates, settings etc) If i let my games go over 60 FPS in game, the stream stutters miserably...

Now on the other hand, I have an in home server PC Ryzen 1700, gtx 950, 32gb ram, that has a 144hz monitor connected to it for when my wife games. I used the same streaming settings as my gaming PC, with the game at 144hz, the stream off that PC works flawlessly.

It's not just OBS, Nvidia shadow-play does the same thing... It didn't used to, until I upgraded to my GYSNC 1440p 165hz monitor. I'm starting to think it's something to do with the display port.

I do have a secondary monitor on my gaming rig, at 60hz 1080p connected to the iGPU on my MB. I've googled and googled, and also just reinstalled my windows from scratch. So it's not a driver issue. I'm at a loss and could really use some help.

Log file from last stream.

Same issue here, new 1440p 165hz monitor and big stuttering in BF3 recordings, while the game runs smooth at 170-200 Fps. I have 2 1070's installed in Sli configuration.

 

[jlw_4049]

Bump. On 1080p at 144hz it was always smooth as silk.

Try recording with Shadowplay... I know that's not ideal, but at least it works for me.
Maybe sometime it will be fixed if it's fixable..

First I would check, if the problem disappears, when you disable the iGPU and connect both monitors to the Nvidia card.
Then you should make sure, that there is no window with GPU acceleration opened on the second monitor.
Last but not least, you need to leave some room for OBS to render the scene (done via GPU!). I see render lag in your log file, so it seems, your game is running uncapped (no fps limit) or the cap is not low enough, so your game will use >90% GPU load and OBS will not render fast enough.

Ingame, the Ryzen might push lower max frames then the 6700k, and that is why in this case, the GPU is not the bottleneck.
