Question / Help Artifacting

Arimil · Sep 18, 2013

I'm have a strange issue with artifacting, during my stream. It's much less noticeable while the game isn't moving however if I start moving or rotate the camera it is very much noticeable.

Here's an example: http://www.twitch.tv/arimil/b/463355496

And here's the log for that stream, please ignore the streams done at 800Kbps, the stream I linked was done at 1900Kbps.

MMOs are some of the hardest games to make look good to the nature of the high motion camera rotations. The only way to make it look better is to crank up the bit rate (if you can, and don't go higher than 3500) and user a lower x264 preset (if your system can take it).

Looks fine to me. Encoding sharp text over a moving background is tough on the encoder. If you're unhappy the only thing you can do is throw more bitrate at it.

Alright, I lowered teh x264 preset to fast and was able to keep 60fps in-game while using ~90% of my CPU during high motion and I also upped the bitrate to 2600 which is about as high as I can handle. And it looks quite a bit better so it seems this is the best I can do, thanks for the help everyone.

You might consider doing 48FPS. Will reduce CPU strain, help overall picture quality, and still look noticeably smoother than 30fps.
