UPDATE: 1 May 2024
A proton hotfix will fix problems on Steam deck OLED - on X bt Pierre-Loup Griffais from Valve
Thanks to the intervention of Pierre-Loup Griffais from Valve, a Proton hotfix has been released to address at least one of the issues, although access to graphical options remains unresolved. The hotfix, now selected as the default layer for the game, appears to have addressed the frame pacing issue on Steam Deck OLED. However, the use of a specific startup option has been suggested to temporarily restore access to the game's launcher. Hopefully, Bethesda will ultimately resolve these issues, making graphical options accessible without the need for additional commands.
