@l33t4opera said in Twitch streams stutter in GX, but not normal Opera:

Hi @justtheaverageuser, first of all, the issue may be a bit more complicated for Opera GX, since it's quite fresh and different product from the "normal" Opera stable. Also, the streaming may behave differently on certain hardware - I mean CPU/GPU models.
The version of Chromium in both Operas is the same for now, so it shouldn't be cause of the problem.

However, when it start stuttering, you can try few more things:
1. Change to lower video quality in Twitch.tv player - for example 720p or 480p. Maybe that will help a bit in your case,
2. Check if the "Low Latency" option is enabled under Advanced, and if not enable it, and see if it makes any difference,
3. Enable "Video Stats" in Advanced, and see if it drops a lot of frames under "Skipped Frames".
If so, make sure that the player is not using the flash plugin (instead of H.264 codec).
It shouldn't use it, since it looks to be dropped a while ago. But if this is the case, you can try to disable HW acceleration in the plugin - there are many videos/tutorials on the internet on how to do that.

Actually disableing the Low Latency option fixed it for me. I dont have the problem anymore.
