Data shows that 90% of Windows games can currently be run on Linux systems, which marks the continued improvement of the compatibility of open source operating systems in the field of PC games. Statistics show that most players can now successfully experience most games on Linux systems, with only a few exceptions still having compatibility barriers.
This progress is mainly due to the joint efforts of the Linux community and related projects. ProtonDB is an unofficial community website based on user reports and focused on Valve Proton technology. This technology originated from the Wine project and provides a conversion layer for Windows native APIs (such as DirectX), allowing many games that originally only supported Windows to run on Linux. ProtonDB rates games based on compatibility levels - "Platinum" levels where games run flawlessly out of the box, "Gold" levels which run smoothly with only minor adjustments, "Silver" levels where playability is slightly lacking, and "Bronze" and "Corrupted" which represent games with poor usability or complete inability to run.
Professional website Boiling Steam pointed out that Windows games that cannot run on Linux are rare, and currently only account for 10% of the total. In other words, about 90% of Windows games can now be experienced on the Linux platform, even if some still require appropriate settings or patches.
Not only that, the proportion of games with "Platinum" and "Gold" ratings is also continuing to rise, and more and more Windows games have achieved a satisfactory experience on Linux systems. Although some games (such as March of Giants) are deliberately set up to prevent Linux compatibility, and some rely on anti-cheating systems that do not yet support open source platforms, the overall trend is still good.
As an important promoter in the PC gaming field, Valve is committed to making Linux a first-class gaming platform through Proton technology and the Steam Deck handheld series. Valve also actively cooperates with game developers to promote Linux compatibility of games from the early stages of development. With Windows 10 about to end support, it is expected that more players will switch to Linux systems in the future.
