Thanks. But I use the way to add “ -opengl” into the code of Nonsteamlauncher, and then reinstall epic, it works as well.

Same problem. Can’t use Epic Games in gaming model since I got my Oled SD. Hope our genius can fix this problem soon.

You are my hero of today! It works! Thank you!

Fozar Horizon 4. With default high graphic settings, it can run at 90hz, and it is really a nice view on this oled screen. It is the best game get the best upgrade from my side. Civilization VI is also a nice one with the bigger screen it looks much better.

Answer to your questions:

1. Yes. Steam Deck is a standalone console, not a streaming console, and you can even play many games offline.
2. Oled version is really better than the Lcd one. You can search a lot of comparison videos between these two devices for more details. I had a lcd one before I get the oled one, so I can say the bigger screen indeed makes some difference, but it should not be the core reason to upgrade lcd from oled version.

I don’t know about the second hand market so I can’t give you advice on your third question. But a Steam official verified second hand device could be a nice option I think.

Cloud saving is a problem due to the differences Windows and Linux. I also have some cloud saving problems in my games, like Elden Ring, Divinity Original Sin 2, Octopath Traveler 2. But still many games don’t have this problem like Witcher3, Sekiro. Anyway so far I haven’t found any solution on this issue, I searched a lot places and times, no solutions so far.

Yes. After many times reboot, probably over 10 times, I finally can launch horizon 4 in gaming model, but still no video in the beginning, the screen will be black about 30 seconds then you can see the entry page, press A to enter the game, then everything goes well. I don’t use any GE proton, and didn’t do anything special.

Epic, EA, Uplay are very well on SD, and you can add them in your Steam library and install games on their platforms. Google non steam launcher, it is very helpful.
