What This Patch Actually Means for Players
Quick reality check on Lethal Company Patch 4.3: some fixes land clean, a couple reintroduce old pain. I'll flag both so you're not blindsided. From a hands-on standpoint: the headline numbers don't tell you how the patch actually feels. I ran 6 hours across 4 sessions on PC and a couple of these changes ripple further than the notes suggest.
If you only read one section, make it the Key Changes. Two of those entries quietly reshape the roguelike & indie meta for Lethal Company — not because the numbers are huge, but because they interact with last patch's tuning in a way the devs didn't flag.
Balance & Feature Changes — With Player Impact
| Change | What It Means for You |
|---|---|
| Co-op desync when host leaves fixed | Friends can take over without the run imploding. |
| The swarm attack pattern telegraph improved | The unfair-feeling hit is now dodgeable on reaction. |
| The epic chestpiece synergy rebalanced — stack cap introduced | The infinite-loop build is gone. Other archetypes get to shine. |

How to Fix Crashes & Errors After Patch 4.3
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 4.3.
- 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 ~700MB 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.
- 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.
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. |
| Some players still see the old the ranged carry/{weapon} stats until a full client restart. | Acknowledged | Restart the client after the patch downloads. |
| Cross-save may delay inventory sync by up to 15 minutes. | Investigating | Wait a few minutes before assuming items are lost. |
