Diablo IV Ultra textures setting is missing. Running through battle.net on Bazzite 42 Gnome with ProtonGE latest.
This is on a system running the required hardware (32GB RAM, 24GB VRAM) for the setting to show, like on Windows. iGPU is disabled in BIOS so the system can use the full RAM size.
I tried finding environment variables that would maybe change the detected RAM requirements by Diablo IV, but no luck.
Hopefully this issue can be solved easily, thanks. I also wanted to see whether other people are encountering this issue.
