A technological leap: nearly 90% of Windows games are now compatible with Linux thanks to Proton and Wine
For several years, developers in the Linux community, and Valve in particular, have revolutionized the gaming experience on this platform. The culmination of this progress can be seen today in an impressive statistic: nearly 90% of games designed for Windows now run on Linux.
This evolution is primarily due to the combined efforts of projects like Proton, a tool developed by Valve that acts as a compatibility layer, and Wine, the long-standing project that has translated Windows calls to Linux for decades. Proton works by translating the DirectX graphics APIs, used primarily on Windows, into Vulkan, the modern cross-platform standard. This conversion allows Windows games to run in a Linux environment with often comparable performance. Wine serves as the underlying technical foundation and has a long history of adapting Windows applications, but Proton adds targeted optimization for gaming. These advances have been supported by a growing software and hardware ecosystem: the ever-increasing popularity of the Steam Deck, the handheld console running SteamOS (a specialized Linux distribution), has encouraged Valve to improve the compatibility of its titles. Popular distributions like Linux Mint, Zorin OS, and SteamOS benefit from these innovations and offer ideal environments for PC gaming.
Linux users have long suffered from a limited game library, often restricted to native titles or games running through inefficient emulators. Now, thanks to Proton, Wine, and their integration into platforms like Steam, the world of gaming is much more accessible. Almost the entire Windows game library is accessible without excessive technical contortions, even with a standard installation of a recent Linux distribution. This record of “nearly 90%” proves that Linux is increasingly establishing itself as a viable and comprehensive platform for gaming, a market traditionally dominated by Windows.

- Steam Deck: A portable console running SteamOS that has boosted the popularity of gaming on Linux.
The Different Levels of Windows Game Compatibility on Linux: Understanding the Nuances The statistic mentioned earlier masks a more nuanced reality: Windows game compatibility on Linux falls into several categories, reflecting varying degrees of optimization and stability. This classification is based primarily on criteria defined by the ProtonDB community and confirmed by specialized websites like Boiling Steam. Compatible Linux games are generally divided into five levels:
Platinum:
- The game works perfectly, right out of the box, without needing any additional settings. Gold:
- The game is playable after a few minor adjustments or configurations. Silver:
- Playable, but with some visible imperfections or minor bugs. Bronze:
- There are issues impacting gameplay, but the game is sometimes accessible with extensive tweaks. Broken:
- The game doesn’t launch or crashes consistently. This level of detail is important for gamers concerned about the user experience on their Linux machines, often equipped with NVIDIA or AMD graphics cards that are Vulkan-compatible but sometimes require well-configured proprietary drivers. The distinction is also crucial for evaluating playability on more modest configurations than the Steam Deck, for example.
Valve’s main objective remains to expand the share of “Platinum” and Gold titles, especially for new releases, to enable a plug-and-play experience comparable to Windows. Indeed, regular Proton updates include patches specific to the latest games and improve graphics rendering management, notably through the DXVK project, which translates DirectX 9, 10, and 11 to Vulkan with a significant performance boost.
To go even further, gamers can take advantage of Lutris or the Heroic Games Launcher, alternative platforms that allow them to manage and automate the integration of Windows games on Linux through various community tools and patches. A 5-level classification of Windows game compatibility on Linux (Platinum, Gold, Silver, Bronze, Broken).

The end of support for Windows 10 marks a significant milestone in the computing ecosystem. Microsoft is now pushing for Windows 11, which, however, imposes strict hardware requirements, notably the need for a TPM 2.0 chip. This requirement renders several older or non-standard PC configurations incompatible, leaving some gamers unable to continue enjoying their games on Windows.
Faced with this transition, many users are exploring Linux as a serious alternative, especially since the platform has now reached remarkable technical maturity in the gaming sector. With nearly 90% of Windows titles accessible, Linux positions itself as a stable, scalable, and often more privacy-friendly option.
This shift is also influencing hardware manufacturers and graphics driver developers. Open-source driver projects for Intel Arc GPUs and improvements to NVIDIA drivers under Linux demonstrate a growing interest in this platform within the gaming industry. Meanwhile, Valve continues to promote its SteamOS distribution and Steam Deck hardware, which directly competes with Nintendo and even some laptops in terms of portability and performance. Thus, as Windows 10 fades into obscurity, the timing seems right to question the long-term viability of Windows as an exclusive platform and to definitively solidify Linux’s position in the gaming landscape.

- Optimize your gaming experience on Linux: essential tips and recommended tools
- To fully enjoy Windows games on Linux, a well-controlled configuration is essential. While Proton handles most cases, several best practices can help avoid frustration. First, it’s advisable to choose a distribution known for its hardware and gaming support, such as MX Linux 25 or Ubuntu Linux and its gaming-oriented variants. Selecting the right graphics driver is a crucial factor. Gamers with NVIDIA cards should install the proprietary drivers available through repositories, which are particularly optimized for Vulkan. Similarly, AMD offers near-native support thanks to the Linux kernel and Mesa drivers, whose optimizations are constantly improving. In terms of tools, installing Lutris simplifies the management of Windows games requiring specific configurations or particular wrappers, while the Heroic Games Launcher compensates for the lack of native clients for some stores like Epic Games. These programs often integrate Proton and custom configuration scripts to overcome technical hurdles. It is also advisable to explore Proton options via Steam, particularly Proton Experimental, which includes the latest fixes and optimizations in advance. Users can also take advantage of custom configurations to improve controller support, using dedicated drivers such as the one from the Flydigi Apex 6 project.
