These seven things helped me be able to set up my stream and start running it well, so now I want to share them with you.

If you just want the cliffsnotes version, here it is:
Scale everything to 720p
Use Game Capture
Use Stream Elements
Use Static Assets
Use Good Lighting
Use Hardware Encoding
Lower Your Camera Resolution
One thing to note, if you do switch to hardware encoding, restart your computer for it to take effect.
I hope this helps!
