What This Patch Actually Means for Players
Logged about six hours on Space Engineers since Patch 6.6 hit the servers. The patch notes read one way; the actual feel is another. Here's the gap. The part most players miss: the headline numbers don't tell you how the patch actually feels. I ran 6 hours across 3 sessions on PC and a couple of these changes ripple further than the notes suggest.
Netcode feels more honest after Patch 6.6. I'm getting fewer 'how did that register?' moments, which is the boring but important win. The flashy balance changes get the clicks; the rollback fixes are why you'll actually stay.
Balance & Feature Changes — With Player Impact
| Change | What It Means for You |
|---|---|
| The crafted platform crafting recipe rebalanced — needs 5 fewer stone | Early automation gets a small but real head start. |
| 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. |
| Save corruption on auto-save during chunk load fixed | Huge. Back up anyway, but the dreaded zero-byte save is mostly gone. |

How to Fix Crashes & Errors After Patch 6.6
Running into a crash after the patch? These are the most-reported issues and the temp fixes that actually work right now:
- Verify game files through your launcher (Steam: Properties > Installed Files > Verify integrity).
- Update your GPU driver to the latest Intel build — the May/June branches break on this patch.
- Delete the cache folder at Documents/SpaceEngineers/cache, then relaunch.
- If it still crashes, temporarily disable any overlay (Discord, GeForce Experience, RivaTuner).
- Sign out of the launcher and back in to refresh your session token.
- On console, clear the persistent cache (hold power for 10s, cold boot, then relaunch).
- Check the game's server status page — the login queue is failing silently.
- Lower texture quality to High (not Ultra) — the patch raised VRAM usage by ~500MB 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. |
| Some players still see the old {character}/{weapon} stats until a full client restart. | Acknowledged | Restart the client after the patch downloads. |
