So, I'd like to stream. I would very much like to stream. I have a pretty good computer with an i7-2600k, a GTX580, plenty of RAM, and so on. I am also running on a decent connection, with 10mb download and 10mb upload, which should be more than enough to stream. The platform is Twitch.tv.
However, if I put my bitrate higher than 2000, my stream becomes utterly unwatchable. While I don't lose frames, both me and my viewers experience lag in the form of the video pausing to load every five to ten seconds. If I do keep my frame rate at 2000, the stream looks like garbage and becomes very pixelated. I've tried nearly every possible setting in OBS. Downscaling to 720, messed with CBR, quality balance, CPU presets, nearly everything. The game in question is DayZ, for the record.
I sincerely don't understand how this can occur when I have a fairly good rig and 10mb upload speed. I'd just like to be able to stream at a somewhat decent quality. Someone, for the love of god, help me end this nightmare. How is it that I (and anyone else, for that matter) can watch streams in glorious 1080p without experiencing any lag while mine goes apeshit when downscaled to 720 with a 3000 bitrate?
In this log I played with 3000 bitrate, and the stream stopped to load every 10-15 seconds.
