Hey, friend. I just wanted to let you know that I couldn’t get New Vegas to run on my (up to date) Linux PC until I installed the custom Proton version called “Proton GE.” The GE stands for Glorious Eggroll, which is the username of the developer. There’s guides on how to install it on the GitHub’s readme. I know it may sound complicated to someone new, but you can do it!
Here’s a link to the read me: https://github.com/GloriousEggroll/proton-ge-custom?tab=readme-ov-file#manual
Scroll down to the “native” install instructions.
Of course, you can ignore this if New Vegas just works for you as it seems to for many others. My system is MX Linux, not Mint.
How did you disconnect from the world for a year? Did you go to some very remote location?
