Switch 2 gets the key performance patch first, with one major exclusive mode
MOUSE: P.I. For Hire update 1.2.0 is now available on Nintendo Switch 2, and the headline change is a new Balanced graphics mode that targets 40 FPS on Nintendo’s new hardware. Nintendo Everything reported the Switch 2 patch on July 9, citing the official MOUSE update notes, while My Nintendo News also highlighted the 40 FPS mode as the major addition for Switch 2 players.
That 40 FPS option is the clearest platform-specific change in this patch cycle. The official MOUSE site says the separate Steam, PlayStation 5, and Xbox update is version 1.2.1, while Nintendo Switch 2 receives version 1.2.0 with a similar feature set plus the new Balanced graphics mode. The developer’s post describes the Switch 2 patch as including Level Revisit, quality-of-life improvements, bug fixes, performance optimizations, and “importantly” the 40 FPS mode.
For a shooter, that matters in a practical way. Frame rate affects how cleanly aiming, strafing, weapon swaps, and enemy reads feel in the hand. The sources do not provide frame-time tests, resolution data, or a comparison against the game’s other graphics modes, so nobody should read this as a confirmed technical review of the mode. What is confirmed is that Switch 2 players now have an additional performance target between the usual quality-versus-performance split, and that is exactly the kind of option a fast first-person game benefits from when the tuning holds up.
VRR is now part of the package, but only if your setup can use it
The MOUSE P.I. For Hire VRR addition is also confirmed across the official patch notes. The update adds Uncapped Variable Refresh Rate support, which the official MOUSE site describes as support for smoother gameplay on compatible displays. Push Square reports the same VRR support in the PS5 version 1.2.1 update, alongside general performance optimizations.
The wording matters. VRR is not a magic toggle for every player. The official note ties the benefit to compatible displays, so console owners without a VRR-capable screen should not expect the same result. The sources also do not say whether the VRR implementation behaves identically across Switch 2, PS5, and Xbox, and they do not list supported refresh-rate ranges.
Still, this is the right kind of option for a game built around snap reactions. Uncapped VRR can help smooth out uneven performance when the display and platform support it, and the same patch also includes a broader performance and optimization pass. For players who left because firefights felt uneven or input flow was being interrupted by rough spots, update 1.2.0 gives Switch 2 owners a concrete reason to test the game again rather than relying on launch impressions.
Level Revisit fixes the biggest completionist pain point
The most important non-performance change is Level Revisit. According to the official MOUSE patch notes, players can now replay previously completed levels to collect missing collectibles and finish incomplete side quests. The feature is accessed from the overworld map by driving to a completed level and selecting “Revisit.”
That solves a specific structural problem for anyone who treated MOUSE as a completion run rather than a straight campaign sprint. Push Square calls Level Revisit the headline addition for PS5 because it lets players return for missed collectibles and outstanding side quests. VGTimes, citing the developers, describes it as a frequently requested level replay feature and says it lets players return through the world map to pick up secrets and unfinished objectives.
The patch also accounts for players who already rolled credits. The official notes say finishing the game now transports players automatically to the HUB zone after the credits, giving access to the overworld map for replaying levels. Existing completed saves are covered too: players who have already completed the game can select “Continue” or reload the latest save file from the main menu, which will move them to the HUB zone and open the map. That is the kind of post-launch fix that directly changes whether a lapsed player can clean up a file without starting over.
Weapon wheel and control changes aim at moment-to-moment readability
Update 1.2.0 is not only about replay access and display options. The official Switch 2 notes include upgrades to the Weapon Wheel, with weapon upgrade levels now shown directly on the wheel and improved visual states for readability. Nintendo Everything’s summary also notes enhancements to the Weapon Wheel, horizontal axis inversion, settings menu navigation improvements, controller rebinding improvements, and bug fixes.
Those are smaller changes on paper, but they feed into the same shooter problem: decision speed. If the weapon wheel is easier to read and upgrade levels are visible without extra menu digging, players can make cleaner mid-fight choices. That is especially useful in a first-person game where weapon selection, cooldown memory, and enemy pressure all compete for attention.
The horizontal axis inversion option and rebinding improvements also matter for players who bounced off the controls. The official 1.2.1 notes for Steam, PS5, and Xbox list horizontal axis inversion and improvements to settings menu navigation and controller rebinding, and the Switch 2 update is described by the official site as receiving a similar set of quality-of-life improvements. The sources do not provide a full side-by-side controller menu breakdown, but the direction is clear: this patch is trying to reduce friction before and during combat.
PS5, Xbox, and PC get version 1.2.1, with PC-specific ultrawide support
There is a version-number split that players should not miss. Nintendo Switch 2 is on update 1.2.0, while Steam, PlayStation 5, and Xbox receive update 1.2.1. The official MOUSE site lists Steam build ID 24068822, PlayStation 5 version v02.002.000, and Xbox Series X|S version v1.2.1.0 for the broader 1.2.1 release.
The shared features include Level Revisit, Uncapped VRR, performance optimizations, Weapon Wheel changes, horizontal axis inversion, settings menu navigation improvements, controller rebinding improvements, and a large bug-fix pass. Push Square reports that the PS5 update addresses progression blockers, glitched Trophies, crashes, sequence breaks, and many fixes across stages, weapons, UI, visuals, audio, text, quests, and more. VGTimes similarly describes dozens of fixes covering progression, saves, performance, UI, weapons, bosses, and quests.
PC players get one confirmed platform-specific bonus in the official 1.2.1 notes: full support for ultrawide 21:9 and super ultrawide 32:9 monitors. That does not apply to Switch 2, and the official Switch 2 post instead emphasizes the new 40 FPS Balanced graphics mode. For console players, the clean read is simple: PS5 and Xbox get the large replay, VRR, quality-of-life, and bug-fix update, while Switch 2 gets those same core priorities with its own 40 FPS performance option.
Should lapsed players return now or wait for the next Switch 2 patch?
If you stopped playing because you missed collectibles, got locked out of side content, or did not want to replay the campaign for cleanup, update 1.2.0 is the return point. Level Revisit directly answers that problem, and the patch notes explain how both new clears and old completed saves gain access to the HUB and overworld map.
If you left over performance, the answer depends on platform and expectations. Switch 2 now has a confirmed 40 FPS Balanced mode, Uncapped VRR support for compatible displays, and a general performance pass. PS5 and Xbox have VRR and performance optimizations through version 1.2.1, but the provided sources do not mention a 40 FPS mode for those platforms. None of the sources include measured frame-rate results, so competitive-minded players should treat this as a strong reason to retest, not proof that every hitch is gone.
There is one reason Switch 2 owners may still choose to wait: the official MOUSE post says another Nintendo Switch 2 patch is planned, with more quality-of-life enhancements and bug fixes coming in the next weeks. No date, feature list, or certification status is given in the provided source material. If you are starting fresh, update 1.2.0 looks like the better entry point than launch. If you are highly sensitive to performance consistency or want the cleanest possible Switch 2 version, the developer has already signaled that the next patch is still in motion.
