For most games, start with the Proton version Steam selects by default. Valve recommends its Steam-client-provided Proton for most users. Switch to Proton Experimental if a recent change may address a specific problem, or try GE-Proton when its documented patches match that problem. No version is universally best: compatibility can vary by game, Proton update, and system.

What is Proton, and why are there different versions?
Proton is Valve’s compatibility tool for running Windows-exclusive games on Linux through Steam. It uses Wine to help games designed for Windows work in a Linux environment. The different versions are not a simple ladder from “old” to “best”: they represent different sets of changes, with each potentially helping or disrupting particular games.

1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsValve’s guidance is direct: most users should use the Proton provided by the Steam Client. That is the best starting point because it is Valve’s recommended default, not because it guarantees that every game will work perfectly. When a game has a concrete issue, a different branch or custom build may be worth trying if its changes address that issue.
Compatibility is game-specific and can shift when either the game or Proton changes. A game that works on one release may behave differently after an update, and a newer build can bring both fixes and regressions. There is no reliable universal ranking or published success-rate comparison in the official sources cited here.

What is the difference between Steam Proton, Experimental, and GE-Proton?
Steam Proton is the Valve-provided default; Experimental is Valve’s actively updated branch; GE-Proton is an independently maintained custom build with additional patches. Choose by the problem you need to solve, rather than assuming one option is always more compatible.
| Option | Who maintains it | What distinguishes it | When to consider it |
|---|---|---|---|
| Steam Proton | Valve | The Proton version supplied by the Steam Client; Valve recommends it for most users. | Start here, or return here after an experimental change makes the game worse. |
| Proton Experimental | Valve | An actively updated branch that receives compatibility changes; updates may also introduce regressions. | Try it if a recent change or documented fix appears relevant to your game or symptom. |
| GE-Proton | The GloriousEggroll project | A custom build that documents additional patches, including media foundation patches for video playback and game-specific protonfixes. | Try it when its README or release notes identify a fix that matches your issue. |
GE-Proton is not a Valve release. Its project documentation describes it as a custom build not affiliated with Valve and warns that unofficial builds are unsupported. That matters if you are looking for an officially supported Steam configuration: GE-Proton is an option for targeted troubleshooting, not a promise of better compatibility or Valve support.
Which Proton version should you use for a game?
Use the Steam-client-provided Proton first unless you have a specific reason to change it. If something fails, use the game’s symptoms and the relevant release notes to decide whether Experimental or GE-Proton is a reasonable next trial.

- Start with the default. Leave the game’s compatibility selection at Steam’s default and check whether the issue occurs there. This follows Valve’s recommendation for most users.
- Identify what is failing. Note whether the game will not launch, video does not play, audio or controls behave incorrectly, or stability changed after an update. A specific symptom is more useful than a vague goal such as “get better performance.”
- Check the official notes. Look at the Proton releases and Experimental changelog for a mention of the game, fix, or regression. A listed change is a reason to try a version, not a guarantee that it will solve your setup’s issue.
- Try Experimental when the evidence points there. It may contain a compatibility fix that has not reached the regular version you are using. Since the branch changes over time and can introduce regressions, check the relevant dated entry and reassess after updates.
- Try GE-Proton for a matching documented patch. Review its project README and release notes for a fix corresponding to your symptom—for example, a video-playback patch or a listed game-specific protonfix. If there is no relevant documented change, switching to GE-Proton is a less informed experiment.
- Compare the same game across versions. Change one thing at a time and check launch success, video and audio playback, controls, and stability. Keep track of which version you selected and whether the issue began after a game or Proton update.
- Keep the version that solves your issue. If the alternate version fails or introduces a new problem, return to the previous selection. The choice is per game, so you can make different selections for different titles.
How do you change Proton for one game in Steam?
Use that game’s Properties in Steam and change its compatibility tool. Valve documents per-game compatibility selection, as well as launch options and runtime configuration for troubleshooting.
- Open your Steam Library and open the game’s Properties.
- Open the game’s Compatibility settings.
- Enable the option to force the use of a specific Steam Play compatibility tool, if it is not already enabled.
- Choose the available Proton version you want to try, such as Experimental. Choose GE-Proton only if you have installed an appropriate build and it appears in the available choices; the supplied sources do not establish a particular installation method or guarantee that it is already present.
- Close the settings, launch the game, and check the same symptom you were troubleshooting.
- If the result is worse, return to Properties and restore the prior choice or Steam’s default.
Steam’s Proton documentation also covers per-game launch options and runtime configuration. Those settings can be useful for troubleshooting, but do not add launch options simply because a different Proton version did not help; use an option only when you understand which issue it is meant to address.
Does Experimental always have better compatibility?
No. Experimental is updated with compatibility changes, but “newer” does not mean “better for every game.” Valve’s July 2, 2026 changelog says that entry included changes from Proton 11.0-1 along with additional changes, and documents newly playable titles and fixes. Changes in an actively updated branch can also cause regressions.

Check whether the Experimental changelog addresses your particular game or symptom, then try it for that game if it seems relevant. If the problem appears or worsens after an update, compare against your previous choice rather than assuming the newest branch must be retained. Experimental is useful as a targeted option, not a universal upgrade setting.
When does GE-Proton make sense?
GE-Proton is most useful when its project documentation identifies a patch or game-specific adjustment that matches your problem. The project README lists extra media foundation patches for video playback, protonfixes that apply game-specific adjustments, and other Wine patches. Those details give you a reason to consider it when, for example, a documented video fix corresponds to the failure you see.
It is less useful to treat GE-Proton as a generic “stronger Proton.” A custom build may behave differently, and its maintainer says unofficial builds are unsupported. Check the relevant project notes, change one variable at a time, and be ready to switch back if the targeted fix does not help. Do not infer that a patch will solve an issue merely because it is included in a custom build; whether it applies depends on the game and the symptom.

Which Proton releases are current?
Release labels are time-sensitive, so check Valve’s releases page for the latest version before changing a game’s setting. At the available data on November 12, 2026, Valve’s releases page listed Proton 11.0-2e, released October 9, 2026, as its latest release. That is a dated status, not a guarantee that the same version remains latest when you read this.

The Experimental changelog cited above is also a dated entry, not a live summary of every current change. For either branch, use the release notes to check what was added and when; do not assume a version number alone tells you whether it fixes your game.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What should you compare when troubleshooting?
Compare observable behavior in the same game and setup rather than relying on a blanket claim that one Proton version is faster or more compatible. Official change notes describe particular fixes and regressions; they do not provide a universal comparative ranking.

- Launch: Does the game start, and does the original launch failure still occur?
- Video and audio: Do in-game videos play, and is the audio issue you were tracking resolved?
- Controls: Does the relevant input behave as expected?
- Stability: Does the game remain stable in the situation where the original problem appeared?
- Change history: Did the symptom begin after a game update, a Proton update, or a change in settings?
Write down the selected Proton version and the symptom before switching. That simple comparison makes it easier to tell whether a change helped, did nothing, or created a regression. If more than one setting changes at once, it becomes harder to identify which change caused the result.
Frequently Asked Questions
Can I use different Proton versions for different games?
Yes. Steam’s compatibility selection is made through each game’s Properties, so you can leave most games on the default and set an alternate tool only for a title that needs it. A change for one game does not require you to switch every game to the same version.
Recommended Free Tools
Where can I see whether a Proton update mentions my game?
Check Valve’s Proton releases page and the relevant Experimental changelog entries for the game name or the symptom you are investigating. Release notes are dated: a mention provides context for that change, but does not confirm that it fixes every configuration.
Does a newer Proton version guarantee a higher frame rate?
No universal performance advantage is established by the official documentation cited here. The release notes document compatibility changes, not a general benchmark ranking, so choose a version based on the behavior you can verify in the game you are troubleshooting.
