Hello, I have absolutely no experience streaming and would really appreciate some advice on the settings I should use with my rig:

i5 6600K OC @ 4.5Ghz
Corsair H100i GTX liquid cooler
16GB ram (2x8 DDR4 3200 GSKILL Vsync)
Gigabyte G1 Gaming 970 GTX x 2 SLI
Samsung 950 PRO M.2 256GB SSD
Western Digital 2TB Black Caviar HDD
Acer Predator XB271HU ISP G-Sync Monitor 2560 x 1440

Internet: 180Mbps Down, 10Mpbs Up

I play my games maxed out @ 2560 x 1440, 165hz w/ gsync enabled.

I'd like to get the best quality stream without sacrificing smooth playback for the viewers. Currently I'm using these settings:

x264
3300 max bit rate
2560 x 1440 base resolution
1.5 (1706 x 960) resolution downscale
60 fps

Any suggestions?

Thanks!

Assuming you are streaming to Twitch, and are not a Partnered streamer, the best settings do not change:
720p@30fps, 2000kbps, x264 encoder, Veryfast preset (or lower, depending on CPU usage).

2000kbps is the point where most Twitch viewers will be able to watch without buffering. Going even to 2500kbps will cause quite a few to start.

720p@30fps fits into that bitrate budget as the best tradeoff between resolution and framerate smoothness. If you have a technical reason to need 60fps, like playing a retro game that uses sprite blitting for transparency and the sprites disappear or stay solid at 30, you can downscale further to 480p and get 60fps going to solve that. Otherwise it's mostly just a waste of bitrate for non-partners, and numbers-wanking.

Plus, i5s tend to run out of gas as far as real-time video encoding much past 720p@30fps anyway... maybe 60fps with a CPU-light game.

3300kbps is not enough for 960p@60fps. 1080p@60 starts around 5500kbps. Why only Partners really can use it.

OBS also isn't compatible with GSync. Very little is, for that matter. It tends to cause significant issues as it is a proprietary technology. Give it a shot, but most people have to disable it and go back to VSync, which is an open standard.


So yeah: 720p@30fps, 2000kbps, x264 Veryfast (or lower, depending on testing).
