What This Patch Actually Means for Players
Quick reality check on Mortal Kombat 1 Patch 5.5: 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 5 hours across 2 sessions on PC and a couple of these changes ripple further than the notes suggest.
Netcode feels more honest after Patch 5.5. 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 |
|---|---|
| Netcode rollback buffer tuned | Cross-region matches feel more honest. Whiff-punishing online is viable. |
| The support main hurtbox shrunk during the overhead | Some 'illegal' punishes no longer work. Frame-trap setup needs a rethink. |
| Hitstun on the heavy normal normalized across the assault operator variants | Combo routing is consistent now. Less character-specific jank. |

How to Fix Crashes & Errors After Patch 5.5
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/MortalKombat1/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 ~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.
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 |
|---|---|---|
| Controller rumble stays on after disconnecting a pad. | Known | Reconnect and disconnect the controller again to reset it. |
| Some players still see the old the support main/{weapon} stats until a full client restart. | Acknowledged | Restart the client after the patch downloads. |
| Friends list intermittently shows offline users as online. | Investigating | Reloading the social tab usually clears it. |
| HDR displays may clip whites in the {area} menu. | Being worked on | Lower HDR peak luminance to 1000 nits in the system menu. |
