What This Patch Actually Means for Players
Logged about six hours on Subnautica since Patch 1.5 hit the servers. The patch notes read one way; the actual feel is another. Here's the gap. Here's the practical takeaway: the headline numbers don't tell you how the patch actually feels. I ran 7 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 |
|---|---|
| Memory leak in long sessions patched | You can leave the world running overnight without the RAM climbing to the moon. |
| The patrol unit pathing fixed near player-built structures | No more zombies phasing through your walls. Bases actually defend now. |
| Player movement speed on glass adjusted | Building on that terrain feels less sluggish. Pathing through bases is smoother. |

How to Fix Crashes & Errors After Patch 1.5
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 1.5.
- 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.
- Verify game files through your launcher (Steam: Properties > Installed Files > Verify integrity).
- Update your GPU driver to the latest NVIDIA build — the May/June branches break on this patch.
- Delete the cache folder at Documents/Subnautica/cache, then relaunch.
- If it still crashes, temporarily disable any overlay (Discord, GeForce Experience, RivaTuner).
- Lower texture quality to High (not Ultra) — the patch raised VRAM usage by ~600MB 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.
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 |
|---|---|---|
| HDR displays may clip whites in the {area} menu. | Being worked on | Lower HDR peak luminance to 1000 nits in the system menu. |
| High refresh rate monitors may cap at 60fps in borderless mode. | Pending fix | Use exclusive fullscreen until the next hotfix. |
| Cross-save may delay inventory sync by up to 5 minutes. | Investigating | Wait a few minutes before assuming items are lost. |
