Hey,
So as the title says, I've been trying to stream a few things around on Twitch.
While The Binding of Isaac Rebirth is perfectly okay ( despite a 10+ sec latency, which isn't that bad actually ), the [way] more demanding Assassin's Creed Unity has proven to be a failure thus far.
During actual gameplay, I've got no issues whatsoever, the game runs perfectly fine at almost top quality settings. I've even lowered a few options in order to reduce the overall load on the computer ( second to last textures / details options, no soft shadows, FXAA, no Vsync, etc ).
The preview in the OBS window is a bit choppy, which is fine by me as it's not as choppy as to drastically prevent viewers from experiencing the game. What's more it's still actually good for a not anymore top-of-the-line computer.
However... When I display the twitch channel to check on the results, it's just terrible. It's choppy, laggy, and always trying to buffer.
I've tried a wide range of options, from low buffer to custom CFR, from X264 to NVenc, from 480/30 fps to 1080p / 60fps, and I never witnessed any improvements. I even lowered the whole game options to ultra low just to be sure, and it still wasn't good. Basically I feel like I've run out of guides, tips and shared settings I could find, here or on Youtube or wherever.
Thing that bothers me the most is I have no idea which step is going wrong. Encoding ? Uploading ? Or even watching the stream myself at the same time ? Although with almost 300 / 50 Mbps I would hope I can still upload a 'low'-bitrate video and watch it at the same time.
It should be noted some of my friends also reported to me the stream wasn't exactly performing well.
Also, I tried both streaming and plain capture, both with OBS and Shadowplay. Shadowplay gives me a perfect local video, OBS gives me the same choppy video. Both however give me bad stream results on Twitch.
So any idea? At this point I'd just say my rig isn't powerful enough to stream ACU, but I'm not ready to give up on it yet. I may want to stream some other high-quality-looking games in the future anyway...
