I recently started playing Throne and Liberty after seeing a YouTube video on it.

It goes all-access on October 1st, but you can buy a pass to get early access now.

Proton

I'm playing Throne and Liberty on Steam on Linux.

I had to enable "Proton Experimental to get it to run.

I was also running into performance issues and crashes due to running out of video memory. I was able to solve these by disabling DirectX 12:

1. Open Settings
2. Go to Graphics > Quality
3. Disable Use DirectX 12
