Slime Rancher 2 carries the Steam Deck Verified badge — but there’s a distinction worth knowing before you boot it up. Valve awarded that badge after their own compatibility testing. Monomi Park, the developer, has explicitly stated the game is not officially supported on Steam Deck and will not accept Deck-specific bug reports unless the issue reproduces on PC or Xbox Series X/S [2]. That changes how you approach the game on handheld: community-tested settings are your most reliable source, not a developer settings guide.
The community has done the work. The settings profile below comes from Steam Deck HQ’s tested configuration [1] and corroborates with ProtonDB reports [3]: native 1280×800, 40fps cap, 9W TDP, FSR off. That profile runs stable in the open world and burns around 3.5 hours of battery — genuinely playable without a power cable.
Best Slime Rancher 2 Steam Deck Settings at a Glance
| Setting | Recommended Value |
|---|---|
| Frame Rate Cap | 40 FPS |
| TDP Limit | 9W |
| Resolution | 1280×800 (native) |
| FSR / Upscaling | Off |
| GPU Clock | Auto |
| Proton Version | Proton GE (latest) |
In-Game Graphics Settings
These settings are dialed for 40fps stability across SR2’s three main biomes — Rainbow Island, the Ember Valley, and Starlight Strand. Your ranch (the Conservatory) is the exception; see the TDP section below for how to handle it.
| Setting | Value | Why |
|---|---|---|
| Shader Quality | Medium | Good balance of visual fidelity vs GPU load |
| Antialiasing | None | AA is expensive; SR2’s art style tolerates aliasing well |
| Depth of Field | Off | No gameplay benefit; costs GPU cycles |
| Bloom | Off | Saves GPU; minimal visual impact in SR2’s bright palette |
| Chromatic Aberration | Off | Post-process effect with no performance benefit to keeping it |
| Ambient Occlusion | Off | High GPU cost relative to visual gain on a handheld display |
| Reflections | Off | Cuts GPU load significantly; water still looks fine |
| Model Quality | Medium | Slimes look good; no visible pop-in at medium |
| Subsurface Scattering | Off | Shader effect; not worth the overhead on 7nm hardware |
| Particles | Low | Slime bouncing generates a lot of particles — keep this low |
| Textures | Medium | High textures require VRAM the Deck doesn’t have to spare |
| Shadows | Low | Biggest single GPU savings; Low shadows are still clean |
| Fog | Normal | Minimal GPU cost; fog adds depth to outdoor areas |
Why FSR Is Disabled — Don’t Enable It
Most Steam Deck settings guides turn FSR on by default. For SR2, do the opposite. Enabling FSR at any quality level causes the HUD to scale incorrectly — inventory icons distort, UI elements shift, and the screen overlay becomes hard to read mid-game. The bug isn’t subtle; it actively makes the game worse.
The reason FSR should be skipped anyway: the game’s GPU demand at these settings doesn’t require it. SR2 runs native 1280×800 at 40fps within the 9W TDP budget. You’re not GPU-bound, so upscaling adds visual cost (FSR artifacts in the foreground) and UI breakage for zero performance gain. Keep FSR off and run native resolution.

TDP Settings and Battery Life
The 9W TDP cap covers most of SR2’s gameplay. Open-world exploration, collecting slimes, and navigating the caves all sit comfortably within that budget. The Conservatory is the one exception: when you have a full ranch of slimes actively bouncing and producing plorts, CPU and GPU load climbs. If you see consistent drops below 40fps on your ranch, nudge TDP to 10–11W to cover it.
Running uncapped at max settings pushes the Deck to 80–87°C and 24W draw — that’s under 2 hours of battery and thermal throttling territory. The 40fps/9W profile is meaningfully better for actual handheld use.
| Profile | TDP | Battery Life | Best For |
|---|---|---|---|
| Recommended | 9W | ~3.5 hours | On-the-go play, all biomes |
| Ranch-heavy sessions | 10–11W | ~3 hours | Large slime populations |
| Plugged in, quality mode | Uncapped | N/A | Docked or bedside with charger |

Known Issues on Steam Deck
A few rough edges to know going in:
Intro cutscene drops — the opening sequence has significant frame drops and screen tearing. This isn’t representative of gameplay; the game itself runs smoothly once you’re in-world.
Conservatory frame dips — directly tied to slime count. The more slimes active in your ranch simultaneously, the higher the CPU load. Keep ranch populations reasonable if you want smooth performance without bumping TDP.
No official support path — if you encounter a Deck-specific bug, Monomi Park won’t investigate unless it also reproduces on PC. Use ProtonDB and the Steam community forums to find workarounds.
Frequently Asked Questions
Is Slime Rancher 2 Steam Deck Verified? Yes — Valve’s testing awarded it the Verified badge, meaning controls work natively and the game launches without manual configuration. The developer has not officially supported the port.
What frame rate does SR2 run on Steam Deck? With the settings above, 40fps stable through open-world exploration. Ranch performance dips when slime populations are high — raise TDP to 10–11W to compensate.
Can SR2 run at 60fps on Steam Deck? Technically possible at max power, but not recommended. It requires uncapped TDP (80–87°C, ~24W draw) and delivers less than 2 hours battery. The 40fps profile is significantly more practical.
Should I use FSR in SR2? No. FSR breaks the HUD in SR2 — inventory and UI elements scale incorrectly at any FSR quality level. Run native 1280×800 with FSR disabled.
