slow fb stream

Please help me with my steaming on facebook. first was really good when im using my settings on it on obs this is the output of the quality. https://prnt.sc/cNZMS4W2_FtI the "Source" was so really good. so smooth. (Even this is good on my 1050ti) after that when I update the drivers of my GPU...

Good day! May I ask why is it always lagging? Is there internet speed requirement? Or do I need an internet speed booster? I hope you could help me to fix this. The app is great. That's the only issue I'm facing so far.
