Streaming in browser is horrible

I just tried streaming in Chrome and Edge on my PC and holy (Edited per community guidelines) is it horrible. It used to be crystal clear and now it's simply unwatchable - it can't even be 480p resolution.

Streams look fine on my Rokus and on my phone, not the browser, which my son uses exclusively in his room as well, is just unbelievably bad. I watch tons of baseball at my desk while I work and have some it for years. This is simply not the product I'm paying for anymore.
