Ubuntu Gaming vs. Windows: Which Fits Your PC?

Ubuntu can replace Windows for some gaming PCs, especially if your Steam library is mostly single-player. Whether it works for you comes down to the games you need to play, their anti-cheat support, and any Windows-only software you rely on. Arol Wright’s November 6, 2026 assessment of Ubuntu 26.04 LTS makes a conditional case, not a universal one.

Before replacing Windows, check every must-play game and the apps you use to configure your gaming gear. Either one can decide the switch.

Proton makes many Steam games possible, but compatibility is per title

Proton is Valve’s compatibility layer for running many Windows games on Linux through Steam. That can make an Ubuntu library feel familiar: games may launch from Steam, but one game working does not guarantee the next one will.

In his November 6 assessment, Wright named Fortnite, Valorant, Warzone, and Battlefield 6 as games that did not run on Linux in his account. He listed Counter-Strike 2, ARC Raiders, and Marvel Rivals as exceptions. Treat those as title-specific examples from that assessment, not a blanket rule for every game or future update.

For games outside Steam, the question is still whether the specific title works. Installing a different launcher does not by itself guarantee compatibility.

BattlEye support depends on the developer and the game

Kernel-level anti-cheat can be a serious obstacle, but BattlEye support on Proton is not categorically impossible. Valve’s Steamworks team says a developer can contact BattlEye to enable support for an individual Proton title, and says enabled games were working on Steam Deck. Valve’s Steamworks statement describes that BattlEye-specific path; it does not make every BattlEye game, other anti-cheat systems, or every Linux game compatible.

That is why your own multiplayer list matters more than the anti-cheat label alone. Check whether each game you care about supports Proton, rather than assuming that one title’s support applies to another.

Graphics performance varies with the game and graphics API

Proton uses graphics translation layers for some Windows games. Wright describes DXVK for DirectX 9, 10, and 11 games, and vkd3d-proton for DirectX 12. These tools translate graphics instructions for Linux; they do not mean every title will perform the same way on both systems.

Wright says DirectX 11 games using DXVK generally held up well, and notes user comparisons in which some Vulkan games ran better through Proton than on Windows. Those are game-specific observations, not a universal performance verdict. The practical takeaway is to judge Ubuntu by the games and hardware you actually use, rather than by a single Linux-versus-Windows headline.

Windows-only apps can matter as much as the games

A game may run while the rest of your setup still depends on Windows. Wright identifies the Xbox app, PC Game Pass, Razer Synapse, and Logitech G Hub as Windows-only in his Linux discussion. He also says community tools may not consistently support newer peripheral features.

Check the functions you use in those tools, such as device settings or profiles, before removing Windows. A substitute that handles basic controls may not cover the features you depend on.

When to use Ubuntu alone and when to keep Windows

Ubuntu is a reasonable candidate as your only gaming OS if your library is mostly single-player, you have AMD graphics, and none of your must-play games requires unsupported kernel-level anti-cheat. That is the conditional fit Wright describes, not a guarantee for every PC.

Keep Windows installed if a required game or companion app does not work on Ubuntu. That gives you a fallback for the parts of your setup Proton or Linux software cannot cover, without making you abandon Ubuntu for everything else.
