I didn’t see a FPS meter because it’s streaming the game and not rendering it on the steam deck gpu. It shows the FPS meter I have running on my computer/source though.

That’s also how I knew HDR was working. I could compare it to my computer’s monitor as it runs it at the same time on screen. In fact you can even control the steam deck through the keyboard and mouse in the source computer.

I feel like HDR was running because side by side it looked similar and it’s definitely enabled on my computer. Was testing Doom Eternal, max settings, 3440x1440, 165fps, HDR and DLSS enabled… No input lag on the steam deck and it looked perfect and played great.

After days of agonizing!

You probably won’t miss out on anything as it will leak out at some point and you can just install it to your cheaper Steam Deck.
