Hi,
So I recently started streaming a couple of days ago and after some modifications to settings seem to have something that is running stable for hours at a time. I am curious if anyone has recommendations based on my logs (from two sessions yesterday, one SC2 and one PS2) on what I could potentially do to improve the quality at all.
I ran the testmy speedtest for 33MB multiple times and always came out to 1.97Mbps (my advertised upload is 2Mbps so not bad :)) but when playing PS2 I do use teamspeak and will occasionally share the internet while streaming when my g/f is home so I don't want to totally max it out. Any input is appreciated since I'm new to this and still learning the ropes.
One thing to note that this doesn't point out as far as I can tell, I do have 2 GTX 460 SC 768MB (both) in the desktop but as best I understand it, OBS has to link into the framebuffer on the primary GPU so correct me if I am wrong. I am aiming for a quality 480p stream, I don't think I have the upload necessary for 720p.
