Since the Steam Proton update is so new, it requires a newer Nvidia driver than what's distributed with Ubuntu 18.04.1. Step 2a: Install The Latest Nvidia Driver I've written an Ubuntu installation guide for beginners, so if you don't have Ubuntu on your PC yet, make this your first stop. Valve has advanced Linux-based gaming by leaps and bounds with this initiative, but proceed with caution knowing this is still firmly in the realm of 'Beta!' I can confirm that many of them work flawlessly. So now, theoretically, the vast majority of games you could only play on Windows can now be installed directly in the Steam for Linux client. It's open source, and the tools are installed seamlessly in the background depending on the game. What Valve has done is improved upon those tools (and employed the main developer of the DirectX to Vulkan project) and published their own version called Proton. While this method works, it's a bit scattershot and requires a ton of trial and error, manual configuration and guesswork.
