Update 1.1.0, released on October 6, 2026, is The Sinking City 2’s first major update. It rebalances four combat encounters, adds HDR output with HDR10+ and an in-game calibration screen, adds AMD FSR 4.1.1 and a new DLSS Legacy mode on PC, adds PlayStation 5 Pro support, sets the Ex Oblivione inheritance rules, adds a fully fresh Pure New Game mode, and adds two free Calvin outfits. The official note counts over 150 fixes and improvements, which is an approximation, not an exact count.
Quick answer
Four encounters were rebalanced: The Wake-Up Call, A Sight for Sore Eyes, Time and Tide, and Cold Comfort, with fewer enemies and waves in overwhelming fights.
HDR output arrives on PC, PS5, and Xbox Series X|S, with HDR10+ support and an in-game brightness calibration screen. HDR follows your system setting.
PC gains AMD FSR 4.1.1 and a new NVIDIA DLSS Legacy mode. What Legacy mode technically means has not been explained by the developer.
Ex Oblivione now inherits inventory slot and weapon upgrades; duplicates found in the second run convert to Dream Essence.
Pure New Game is a fully fresh run with no inheritance. It is not the same mode as Ex Oblivione.

1. Combat rebalance: what actually changed
The official note names four encounters, not four bosses: The Wake-Up Call, A Sight for Sore Eyes, Time and Tide, and Cold Comfort. In fights players called overwhelming, enemy counts and wave compositions were reduced. Explosives were buffed across the board: grenade and gas-canister damage went up, explosive props are easier to spot, and explosive lights are now red. The delay before a Slither weak point becomes hittable was shortened. Companion commentary during boss fights triggers less often. The note does not name Shoggoth or Slither Prime as individually rebalanced, so do not describe this update as a boss nerf or buff for either of them.
2. Graphics settings: HDR, FSR, DLSS, PS5 Pro
HDR output arrives on PC, PlayStation 5, and Xbox Series X|S, with HDR10+ support and an in-game HDR brightness calibration screen. PC also gains multi-monitor HDR. HDR follows your system setting: if HDR is off at the system level, the game does not force it on. The practical order is to enable HDR in your system first, then use the in-game calibration screen. The exact slider and pattern steps inside the calibration screen have not been documented in checked sources, so this guide does not invent them. One patch-note转载 wording describes the calibration screen’s peak brightness range as up to 500 nits on all displays; that is the calibration screen’s range, not a requirement that your display reach 500 nits.

| Upscaler tier | Scale | What it means (AMD definitions) |
|---|---|---|
Native AA | 1.0x | Better than native rendering at moderate cost. |
Quality | 1.5x | Equal to or better than native, with a clear performance gain. |
Balanced | 1.7x | The middle ground between image quality and performance. |
Performance | 2.0x | Near-native image quality with a large performance gain. |
Ultra Performance | 3.0x | Highest performance gain, still representative of native. |
The tier table above uses AMD’s generic definitions, not Frogwares’ game-specific description, and whether the game menu offers all five tiers has not been verified. The same caution applies to hardware scope: whether FSR 4.1.1 in this game is limited to RX 9000 series cards has not been verified. As a guide recommendation, not an official statement: start from 1080p, try Balanced first, drop a tier if the image suffers, and try Quality if you have frames to spare. Enable HDR only when your system already has HDR on and your display supports it. For NVIDIA players, 1.1.0 adds a DLSS Legacy mode and fixes a visual fault when DLSS is off at 4K and 1440p; what Legacy mode technically means has not been explained by the developer, so this guide does not define it. On PlayStation 5 Pro, 1.1.0 adds PSSR upscaling: Quality mode uses strand-based hair, improved Lumen lighting, and higher-quality reflections, while Performance mode renders at a higher internal resolution. Target frame rates and resolutions for the two Pro modes have not been published, so none appear here.
3. Ex Oblivione inheritance and Pure New Game
Update 1.1.0 set the inheritance rules for Ex Oblivione, the post-completion New Game Plus mode. Inventory slot upgrades and weapon upgrades now carry into Ex Oblivione. If you find an upgrade you already own during the second run, you receive Dream Essence instead. The same update fixed a bug where the Holloway Manor revolver upgrade was handed out twice on entering Ex Oblivione. Pure New Game, added in the same update, is the opposite choice: a fully fresh run with no inheritance at all. Do not confuse the two: Ex Oblivione is for re-reading the story with new documents in hand, Pure New Game is for starting clean.

| Mode | Inherits | Best for |
|---|---|---|
Ex Oblivione | Inventory slot upgrades, weapon upgrades; duplicates become Dream Essence. | Re-reading the story with new writings. |
Pure New Game | Nothing. | A fully fresh run. |
4. Outfits, demo, and trials
Two free Calvin outfits arrive with 1.1.0: The Warlock and The King in Yellow. The Steam demo also returns with the update, and the official wording is that demo saves carry over to the full game; exactly what carries, item by item, has not been listed by the developer, so this guide does not itemize it. PlayStation Plus and Xbox trials also became available on the same day. The PlayStation trial is a PS Plus Premium Game Trial; a second-hand summary puts it at one hour, but Sony’s official duration for this game was not located. Xbox lists the game with a Free Trial, with no official duration or save-carryover statement located.
FAQ
Do I need to restart for 1.1.0?
No. The update applies to the existing game. The inheritance rules matter when you enter Ex Oblivione after completion, and Pure New Game exists only if you want a fully fresh run.
Did 1.1.0 change the ending?
No ending change has been announced in the update. Ex Oblivione adds new writings that reframe the story; it does not replace the finale.
Is FSR 4.1.1 available on all AMD cards?
Unverified. Whether the game menu offers all five tiers, and whether FSR 4.1.1 here is limited to RX 9000 series cards, has not been confirmed in checked sources.
