Ah it did indeed show much more info! I could pick out two things that seemed like error messages, I’ll search the internet for them later but gotta run for Christmas celebration in a minute.
When starting Steam it told me “unable to init and enumerate GPUs with Vulkan” and “BInit - unable to initialize Vulkan!”, which sounds potentially serious.
On trying to start the games (and maybe at other occasions too) it told me
Glib-GIO-CRITICAL **: g_setting_schema_source_lookup: assertion ‘source != NULL’ failed
I’ll look into them when I get the time, but I wanted to write them here anyway for completeness. Thank you for your help!
Ah, Proton 7 didn’t seem to help, but I haven’t tried using older drivers yet, I should probably try that next! Thanks!
