Question / Help Weird stutter that i didn't have before.

[Roshav]

Greetings everyone.

I have this little issue here.

I bought a new CPU and MB, edited my stream and wanted to play and stream some games.

The problem is that, whenever i play a small game - it's fine, but when i try to play a bigger game (like PUBG, Middle Earth, Watch Dogs 2, etc.) it looks good on my pc (with high fps), it looks good-ish on OBS but it stutters like hell in twitch.

Can you guys please help?

PC Config:
CPU: Intel Core i7-8700k
MB: MSI Z370 Pro SLI
RAM: 32GB (4x8GB 2133Mhz)
GPU: MSI GTX 1070 Gaming X 8G
PSU: 1200W Corsair AX1200i

Stream settings:

Internet connection:

Zero dropped frames.
Stream where it starts to stutter:

@ 0:55:50 till the end i try different games and things.

There is a log also.

Please guys, it's urgent, i need halp.

shows that there is not enough headroom on the GPU load and your internet connection had trouble to put those kbit/s out to twitch.

Btw: The GPU needs a lot of headroom for smooth 60fps OBS footage:

What do you suggest? To lower in-game graphics?

 

[BK-Morpheus]

First of all there must be an FPS limit (ingame or with additional tools or with activated vsync) and then you can reduce GPU load by lowering game details.
Withouth FPS limit, lower game details will not help, as the computer will try to push as many frames as possible, so GPU or CPU will run into a bottleneck.

The ingame fps should match a multiplier of the OBS framerate (if you want to stream with 30fps for example, you should try to run the game with 30 / 60 / 90 / 120 fps) for the smoothest video.

I have fixed my problem, without limiting the fps both ingame or in the stream. Case is closed now.

 

[BK-Morpheus]

Thanks for not letting any one know, how you fixed it.

So the problem was with my initial streaming setup. Now, on the background i put a Media Source mp4 video which loops. This loop causes stutter. If you render it at 60fps or at the fps rate of your stream - it'll be fine i guess. I have made it in WebM format and it worked for me.
