I finally tried the Stadia+ extension and I am pleased as punch with it. For some reason Stadia was rendering at 720p on my 1440p monitor, according to the Stadia+ overlay. I enabled the overlay first to see how it behaved before changing any setting which could make things better / worse. If set to automatic I get only 720P, but if set to 1080p or 4k the overlay returns Stadia is rendering at each resolution respectively. Of course it is still displaying at 1440p on my monitor but each resolution has varying degrees of fuzziness.

My Stadia controllers work great with chrome. It's nice to not have Steam pop up every time I hit the home button as it does when wired. I got the Wasabi Green Stadia controller and it's so dang beautiful. I sound so stupid saying that, but it is a relaxing color to look at.

As much as I generally do not enjoy multiplayer shooters I am enjoying the crap out of Zombie Army 4. My Stadia tag is SlaveZeo if anyone wants to add me and run some missions.
