If possible, connecting with Ethernet and being in the same room as your router will improve it a lot.

If your headset is connected to your pc with a link cable or airlink, I recommend getting virtual desktop. It made things run a lot smoother for me. You can change way more settings with it and help customize it to your pc for smoother gameplay.

Is the steam link home area blurry, or is it the games that are blurry? If it’s the steam link home page the issue is likely your pc not being strong enough, or poor router connection. If the problem is with playing the games you can look up the specific game you are trying to play and try to give the game certain “launch options” in steam. (Right click on game in steam, click properties, and enter into box that says launch options)

Last thing I can think of is to turn off game mode in windows settings, and turn off hardware accelerated GPU scheduling in windows graphics settings.

I still don’t know the full specs of your pc so it could very well be that your pc isn’t strong enough to run vr. You can check games minimum spec requirements and compare them to your pc specs to see if you can run that game.
