Steam games usually install their own dependencies (on Linux and Windows) the first time the game runs, but if the developer was already relying on this direct component of the operating system and did not add the function of installing it the first time Since the game is Proton, this can mean a problem, because the game needs a component that may not be installed. But for example, you can add some missing component to a game through Winetricks.Įxample: The developer made the game for Windows considering that certain intrinsic Microsoft system tools are already installed, such as Net Framework 4.5. Let's not forget that these software is Open Source, so you can change their default behavior at your own risk, of course. There are some parameters exclusively dedicated to Debug, you can find out more on here. Notice in both images the upper left corner. This enabled feature will bring you, in games that support the function, a screen like Pro Evolution Soccer 2019, which is running on Linux Mint in the example: Of course you can remove any of the words to show only what you want, for example if you only want to see FPS, just leave the word "fps" after " DXVK_HUD = " and before " % command% ", The same goes for the other options. For example, if you want to see the FPS rate, Frame Times, Vulkan version, driver and your video card and other details on the screen, just add this parameter:ĭXVK_HUD = devinfo, fps, frametimes% command% These are the main parameters of Proton and are the ones that most affect games, but there are others that can be useful for debugging a game or evaluating its performance.
