I’m running Win 10 Ameliorated on mine. Manual driver installs were the only big hiccup. Works well otherwise, but it’s not my daily driver.
I can’t really use Linux since my work is deeply embedded in Microsoft everything; I need OneDrive to work dependably.
Dragon Age: Origins came out 15 years ago. That’s a very long time to stay with the same company in the tech sector. It’s not at all unusual that there are so few people left who worked with the engine for the first game.
