This game usually looks horrible on Twitch compared to other games. After a lot of testing and trying here are my recommended settings for what I personally think, looks best.
First and foremost, if you are using CPU encoder (because your CPU is capable of) using x264 fast or medium will yield the best picture results. On the other hand if you want to take advantage of your Nvidia card and use NVENC, here are what I consider the best settings.
Encoder: NVENC H.264 (new)
Bitrate: 6500 Kbps (maximum allowed by Twitch)
Preset: Max Quality
Profile: High
Look Ahead: check
Psycho Visual Tuning: Check
Max B-frames: 2
Resolution: 720P
Framerate: 30
The reason for the lower resolution and lower framerate is because, unlike other games, the foliage on this game is massive. It is also a very fast paced game. Because of that, using higher resolutions and/or higher framerates results in a visual “blockiness” of the foliage, which IMO, looks horrible. There’s just too many color variations happening too fast and even the best encoders struggle to keep everything looking sharp. By turning these settings down, while the gameplay doesn’t look that smooth, the colors and sharpness does. For me, is better, but everyone has different opinions of what is better to them, so if you prefer smoothness over visual quality, you might prefer higher resolutions and framerates.
Anyway, just a recommendation for those who, like me, have been struggling for a while trying to make this game look good on Twitch.
YouTube allows for higher bitrates, which massively help with the “blocky” problem. Facebook live on the other hand is probably the worst streaming platform when it comes to quality (they literally re-encode your already encoded video). The visual quality there is so bad that is not worth trying to look for an optimal configuration.
Anyway, hope some of you give it a try. Who knows, maybe can even be applied to console streaming settings, though I have no idea how that works on console and if settings are even customizable (at least resolution, framerate and bitrate)
