Installed the 0.9 beta yesterday and was able to launch the game but noticed a few issues:
At the character creation screen, you cannot see the graphics for the different races… Instead it looks like a white placeholder in the shape of the character.
When trying to exit the game, it locks up. Have to force kill the process.
When setting the resolution, 5120x1440 is not available, the max is only 3840x1440.
Switched the setting in Steam to use Proton and now:
the game now launches and exits as expected
character races display correctly
resolution options lists 5120x1440
I had an issue with environment reflections flickering constantly. Changed the setting for reflections to low from ultra in graphics options and it stopped. I did try all the settings in-between, but only low worked.
After a few minutes of play, the game is running as expected. But I only played for about 10 minutes.
