I have been trying for nearly a year to get Steam Link app working on my Chromecast with Google TV. My pc is connected via Powerline directly to the router, and the router is connected directly via ethernet to the CCwGTV.

The latency I get when playing games is absolutely insane, and any Bluetooth controllers I connect to the Chromecast stop working when I launch Steam Link. The controller I am using is a Dualshock 4. I have had limited success with a friend's XB1 but still not much of an improvement.

Controller issues aside, the latency is a killer. I think it's because the Chromecast just isn't powerful enough to decode the images and send back input to the pc at the same time.

I'm wondering, should I buy the actual steam link hardware? Is it worth buying it though, at this stage, or is it just horribly outdated? Or should I just try and run the app some other way?

I would appreciate any suggestions you guys have!

EDIT 13/03/22 - I thought I'd update you all on where I got with this. Turns out my brother in law had a steam link physical hardware, so he let me have it and I had a crack.

Same setup as the Chromecast - pc is getting internet from a powerline connection to the router, and ethernet cable running from the router to the back of the Steam Link.

Connecting controllers to the steam link was easy. At one point we were playing Speedrunners with 2x DS4s, 1x XB1 and 1x Switch Pro. Took about two seconds to connect it all up via Bluetooth, but I did need a wired connection for the first one.

Latency is almost non existent. For couch co op games like Speedrunners and Ultimate Chicken Horse I couldn't tell the difference between the steam link and my actual PC.

I haven't tried a FPS yet but Jedi Fallen Order was running really well. I'm sure that any single player game would run brilliantly. I basically have a PS5 in my living room now and I couldn't be happier.

My conclusion is that the problem was the CCwGTV - it just wasn't powerful enough to decode the stream. Having a purpose built device for game streaming just makes so much difference - it has all the ports I could need and just works.
