Hope we get full support for the Steam Deck. Valve has a certification program, would be great if ESO will work seamlessly on the Deck. I would buy ESO on Steam again if this will be the case!
I linked my old account to Steam and I can launch it through Steam or through the normal launcher. Works either way, but I don't think it records the hours in steam if you don't launch it through Steam. Its installed twice though so takes up twice the space.
Eh I already play ESO on my phone with Stadia when away from PC/Steam like in bed, in the bathroom or at work; all I needed was an attachment controller so I went with razer's kishi.
I am owner of a Steam deck 512 GB and have the non-steam version of eso to run get there but the gamepad is not recognized by the deck so currently not usable for me.
Test that it works I could by using my PC via steam link to the deck accessed to use my keyboard and mouse.
Alternatively, I could connect a mouse and keyboard via USB-C hub but remotely quickly test and set up was the first step.
in further steps I must probably test an Xbox controller with the deck via Bluetooth to pair many times I can then operate ESO ...
at the next Steam sale I can think about whether I buy the basic version of steam to test it or ZOS gives me a key what I do not really believe now ...
EDIT:
ok i am further ^^
I have now got the gamepad to run:
parameter:
PROTON_ENABLE_NVAPI=1 PROTON_SET_GAME_DRIVE=1 %command%
in the settings in the game must then explicitly gamepad mode be activated.
it works over game mode in desktop mode you dont get the onscreen keyboard overlay to login
