Can concur. The hdmi cable to my living room broke, and I tried steam link on my shield but it was way too much input lag. With moonlight however I cannot tell the difference anymore, it honestly feels as direct as having it connected via hdmi. This is with direct pc - cat6 - router - cat6 - shield though.
The only reason this hasnt happened with valve is because it’s a private company. Publically traded companies are the cancer of ou society tbh
