If a game does not work, it is usually as a result of incompatible packages, missing dependencies or unimplemented functionality by Wine/Proton. This, nowadays, fortunately works for most games (aside from anti-cheat protected ones, which require a kernel driver that Wine/Proton does not yet have). Dependencies are installed inside the prefix (the "sandbox" still needs the game's redistributables), often with winetricks, followed by an attempt to run the game "as if" it was executed from Windows. A prefix (Wine's terminology for a directory mimicking a Windows sandbox) is created and configured. These tools are often brought in the distribution together on the system at the same time. (with the exception of the starting overhead to interop with these) Since these calls are direct equivalents and treated "as if" DirectX was running, performance is not impacted. so owned by Wine, providing their own "hypothetical" belief on what the function may be doing underneath, and forward it instead to an OpenGL alternative, effectively trying to achieve similar results. MF-Media (media foundation dependencies)įor example, a call to load, transform and shade vertices on DirectX may be re-written from scratch in a new.Proton (forked Wine project, optimized for Steam by Valve).These equivalents have their "own" written substitutes which attempt to "re-invent" what the original SDK calls would possibly achieve from a black box point of view. Instead, several opensource equivalents have been written which attempt to provide identical functionality, ultimately achieving the same result from a graphics point of view. Linux by itself does not support DirectX or any of the aforementioned technologies (Visual C++, MFC. Linux, natively supports only OpenGL and Vulkan. (microcode and firmware being fed through, as a result of NVIDIA driver reverse engineering)Ī huge amount of games use DirectX as their main driving SDK. NVIDIA users have to rely on other alternatives, which often comes packed as blobs. AMD users fortunately have opensource drivers released by AMD itself. The APIs above forward their graphical calls to the underlying driver which then proceeds to talking to the GPU hardware. Lastly, lacking the appropriate driver to do the rendering results in a horseless cart situation.Aside from the frameworks mentioned above, there is a further problem with binary formats and compiled code generated by Windows which Linux does not recognize.Libraries necessary for doing general purpose operations during gameplay, such as saving in-game, loading config.(such as NVIDIA Drivers)įrom these problems, further two complications arise, in particular: Drivers necessary to handle game rendering. ![]()
