Mortal Shell II PC Crashes & Stutter — Fix Guide

The launch build shipped with performance problems on a subset of PCs. A hotfix has already been released. Here's the recovery order that's working for players.

Step-by-step fix order

  • Install the latest game update — a PC hotfix shipped in launch week
  • Update GPU drivers (NVIDIA/AMD both released launch-day drivers)
  • Verify game files in Steam
  • Confirm the install is on an SSD — the minimum spec requires it
  • Disable frame generation and test baseline frame times
  • Turn off overlays (Steam/Discord/recording software)

If crashes persist

  • Check RAM headroom — the game assumes 16 GB free
  • Lower shadows and volumetrics first (biggest UE5 costs)
  • Report exact GPU/driver/config on the official Discord
Do not apply beta-era engine.ini tweaks — several were invalidated by launch patches and some cause new crashes.

Frequently Asked Questions

Is there an official patch for crashes?
Yes, a PC hotfix shipped during launch week; install all updates first.
Why does the game demand an SSD?
UE5 asset streaming: on HDDs, world streaming can't keep up, causing hitches and crashes.
