I'm trying to find some software who is able to stream in full screen with adding the source game, but i guess none is able to fix the bug color palette or whatever it is, so i'm on w-mode. ( i tried Open Broadcaster software but doesn't work)
The quality of your stream depend mainly of your cpu speed and upload speed. Before xsplit didn't give any help to set your option, so it was an headache to configure it, now it does automatically. I didn't change anything in my option, my upload speed don't allow me to stream in a better quality than 480p.
The only things i made in the past was to reduce the fps but it was a long time ago, now i didn't try to change the setting i'm still at 20fps so ppl think i'm fast
To stream i still have this newb w-mode mouse precision, i just reduce my resolution to 1280x1024 with the doblesize of w-mode so my sc look like full screen.
