What This Patch Actually Means for Players
Pulled the patch notes apart so you don't have to. Here's what Oxygen Not Included's Patch 1.2 actually changes the moment you boot it up. Reading between the lines: the headline numbers don't tell you how the patch actually feels. I ran 5 hours across 4 sessions on PC and a couple of these changes ripple further than the notes suggest.
Performance-wise the patch is a net positive on my rig. Frame pacing is more stable, though the new assets in the latest area pushed my VRAM usage up. Budget-card players, heads up.
Balance & Feature Changes — With Player Impact
| Change | What It Means for You |
|---|---|
| Multiplayer desync on simultaneous turns fixed | Cross-play lobbies should stop falling apart mid-match. |
| Gold generation rate adjusted on the continental map type | Opening builds need a tweak; greedy expands are riskier. |
| The island coalition late-game tech tree rebalanced | The doomed-to-lose-until-minute-40 faction has a fighting chance earlier. |
| The cavalry line cost raised by 20 | Spam builds get checked. You have to commit to a real army comp. |
| Pathfinding on sieges fixed | Units stop dancing at the gate. Sieges are finally playable. |

How to Fix Crashes & Errors After Patch 1.2
Running into a crash after the patch? These are the most-reported issues and the temp fixes that actually work right now:
- Cap your framerate (RTSS or in-game limiter) to a stable value — uncapped frames push the GPU past TDP on Patch 1.2.
- Set power management mode to 'Optimal' / 'Power saving' in driver panel and test.
- Reinstall the driver using DDU (Display Driver Uninstaller) for a clean slate.
- Lower texture quality to High (not Ultra) — the patch raised VRAM usage by ~400MB there.
- Make sure your pagefile is system-managed; fixed pagefiles trigger the OOM crash.
- Fast-travel to a nearby node first, then walk in. Avoids the asset spike.
- Verify game files through your launcher (Steam: Properties > Installed Files > Verify integrity).
- Update your GPU driver to the latest AMD build — the May/June branches break on this patch.
- Delete the cache folder at Documents/OxygenNotIncluded/cache, then relaunch.
- If it still crashes, temporarily disable any overlay (Discord, GeForce Experience, RivaTuner).
Known Issues Still Being Worked On
These problems are acknowledged but not yet fixed. Here's the status and a temp workaround for each:
| Known Issue | Status | Workaround |
|---|---|---|
| High refresh rate monitors may cap at 60fps in borderless mode. | Pending fix | Use exclusive fullscreen until the next hotfix. |
| Voice chat volume resets between matches. | Known | Re-check your voice settings each session for now. |
| Controller rumble stays on after disconnecting a pad. | Known | Reconnect and disconnect the controller again to reset it. |
| Cross-save may delay inventory sync by up to 20 minutes. | Investigating | Wait a few minutes before assuming items are lost. |
