The Outer Worlds 1 & 2 Fix Guide

Obsidian’s two Outer Worlds games are a decade apart in engine terms (the 2019 original on Unreal Engine 4, the 2025 sequel on Unreal Engine 5), and their problems are classic examples of each engine’s habits. Saves for both live under %LOCALAPPDATA% (look for Indiana for the original, which was Obsidian’s codename, and the sequel’s own folder). Back them up first.

The Outer Worlds (2019)

A stable game by 2026, after years of patches and the Spacer’s Choice Edition re-release. What still bites:

• Stutter when moving between areas is UE4 streaming. An SSD helps materially; beyond that, capping the frame rate to something your machine holds steadily produces a smoother feel than chasing peaks.
• Crash on launch after years untouched: the boring trio, in order. Verify files, update the GPU driver, disable overlays. This game predates most current overlay versions, and they’re a disproportionate cause here.
• Original vs Spacer’s Choice Edition: they’re separate apps with separate saves. The original’s saves can be imported into Spacer’s Choice, but not the reverse, so decide which you’re playing before building hours of progress. On modest hardware, note that Spacer’s Choice raised requirements noticeably for its visual upgrade.

The Outer Worlds 2 (2025)

A modern UE5 release, with modern UE5 characteristics:

• First launch and post-update launches take time on the shader step. Compilation happening up front is the good outcome; it’s what prevents in-game stutter. Don’t kill the process. A long shader screen after a patch or driver update is the system working as designed.
• After every GPU driver update, expect one slow launch for the same reason.
• Crashes in a UE5 game that ran fine yesterday usually track to one of: a GPU driver updated underneath it (one slow relaunch fixes it), an overclock that was marginal all along (UE5 finds unstable overclocks that older games tolerated, so return the GPU to stock as a test), or files damaged in an update (verify).
• Performance tuning honestly: UE5’s heavyweight features scale down well. The difference between the top two quality tiers is much smaller on screen than in frame cost. Drop one tier before reaching for config-file surgery, and let the upscalers do their job.

Both games

• Xbox/Microsoft Store versions sandbox their saves differently from Steam. If you play on Game Pass and later buy on Steam, don’t count on moving saves without checking the current state of cross-save support for that specific pairing.
• Neither game has an official rollback branch; if a patch genuinely regresses something for you, report it and check Roll Back a Patch for the general options.

Quick reference

Symptom	First move
TOW1 crash on launch	Verify, then driver, then overlays off
TOW1 traversal stutter	SSD; steady frame cap
TOW2 “frozen” on launch after update	Shader compilation; wait
TOW2 new instability	One slow relaunch after driver update; overclock to stock
