[Proton] GRID (2019) Gameplay

*GRID (2019)* now plays out of the box with [Proton 5.13-1](https://github.com/ValveSoftware/Proton/releases/tag/proton-5.13-1b)! Benchmarks at 7:10. Software/Hardware: * Pop!_OS 20.04 * GTX 1660 * i5-8400 * 24 GB RAM A couple of notes: * Framerate dropped a good 15-20 FPS while recording since I couldn't use NVENC with OBS. I suspect it has do with with the recent upgrade of my graphics driver * No MangoHUD as apparently [it doesn't work with Steam Linux Runtime](https://github.com/flightlessmango/MangoHud/issues/369), which Proton 5.13-1 uses * Graphics preset is set to "High" by default and cannot be changed - changing any of the graphics settings causes the game to hang indefinitely * As for the benchmarks, the game says I have 49 GB - it's actually 24 Support [Boiling Steam](https://boilingsteam.com) on [Patreon](https://patreon.com/boiling_steam_linux) or [Liberapay](https://en.liberapay.com/boilingsteam/).
