Start by updating the game and restarting your Steam Deck. If the crashes began after an update, verify the game files and remove any mods. Nixxes has published Steam Deck performance and stability updates, but its official guidance does not identify one cause or universal fix for every Deck crash. If the steps below do not help, contact Nixxes Support rather than assuming a particular Proton setting or hardware change will solve it.
First, narrow down when the crash happens
Before changing settings, note whether the game crashes at launch, during a particular mission, after a recent update, when opening the SteamOS overlay, or only after playing for a while. Also record the game version, SteamOS version and channel, Deck model, and whether you use mods. These details can help distinguish a launch problem from a crash during play; they do not by themselves diagnose the cause.
Try the supported troubleshooting steps
Update the game and restart the Deck
Install any update available for Marvel’s Spider-Man 2, then restart the Deck and test again. Official updates have included Deck-specific performance changes and stability improvements, but their presence in patch notes does not mean every crash has been fixed. The latest update visible in the official Steam announcements reviewed here is an August 11, 2026 hotfix; its notes describe Fresh Start suit improvements, not a Steam Deck crash fix. Check the official Steam announcements.
Verify the game files and remove mods
If the problem started after an update, Nixxes explicitly recommends verifying the installed game files and removing any mods. In Steam, open the game’s Properties, choose Installed Files, then select Verify integrity of game files. If you have mods, remove them before testing the unmodified game. Nixxes’ support instructions give these post-update checks and recommend contacting support if they do not resolve the issue.

Consider the previous-version beta only as a workaround
Nixxes documents a Steam rollback workaround for persistent post-update crashes. In the game’s Steam Library page, open Properties, select Betas, and choose previous_version. This is a workaround, not a guaranteed or permanent fix. Return to the current version when an update resolves the problem.
What the official Deck patches do—and do not—establish
The Deck-related patch notes are useful context, but they do not identify the cause of an individual crash:

| Update | What the official notes say | What that means for a crash |
|---|---|---|
| Patch 9, version 1.508.0.0 | Lists Steam Deck performance optimizations, an improved default Deck preset, and stability improvements. The Steam announcement also says Dynamic Resolution Scaling was enabled for more stable performance at default Deck settings. | Shows that Deck performance and stability received attention; it does not confirm that a particular crash is fixed. Nixxes Patch 9 notes · Steam announcement listing |
| Patch 10, version 1.520.0.0 | Fixed a specific issue where some Steam Deck players who first launched the game while offline saw a persistent PSN account-link error that prevented starting the game; it also lists stability improvements. | This addresses a particular offline-first-boot account-link problem, not all crashes. Nixxes Patch 10 notes · Steam announcement listing |
| Patch 7 and Patch 8 | The Steam notes list fixes for a crash when minimizing the game and a crash when quitting during vehicle chases, respectively. | These are specific historical PC crash fixes; neither identifies the cause of a different Deck crash. Official Steam announcement listing |
| August 11, 2026 hotfix, version 2.810.0.0 | Describes Fresh Start suit improvements based on player feedback. | The announcement does not claim to fix Steam Deck crashes. Official Steam announcement listing |
The Nixxes Patch 9 and Patch 10 support articles display February 23, 2026, while the Steam announcement listing dates those releases May 9 and May 22, 2025, respectively. Those are dates shown by different official pages, not interchangeable release dates.
When to contact Nixxes Support
If updating, verifying the files, removing mods, and—if appropriate—trying the documented rollback do not help, contact Nixxes PC support. Nixxes asks players to include the game log, any crash dump files with the .mdmp extension, DxDiag.txt, and the save file where the issue occurs.
Rank #3
- Operating System: SteamOS 3.0
Nixxes publishes %userprofile%documentsMarvel's Spider-Man 2 as a Windows Documents-folder shortcut for the log and saves. It is not a SteamOS path, and the available official instructions do not provide a Deck equivalent. If you cannot locate the requested files on SteamOS, say so in your support request rather than using that Windows path as if it applied to the Deck. The Nixxes PC support index also lists general guides for crashes, save issues, and launcher troubleshooting.
Changes not established as fixes
The official material cited here does not establish a particular Proton version, launch option, Decky plugin, swap-file change, microSD card, or replacement component as a proven fix for Marvel’s Spider-Man 2 crashes on Steam Deck. Community posts can describe individual experiences, but may involve different patches and configurations; they are not confirmation of a general remedy.
