Helldivers 2's 7.1.1 Hotfix Targets Two Specific Crash Conditions
The September 24 notes cover terminals in fullscreen and superwide windows, not a blanket performance overhaul.

Helldivers 2 Crash Fixes
Helldivers 2's September 24 hotfix, Devoid of Liberty 7.1.1, is a small update with a clearly defined purpose. Arrowhead lists two crash fixes: one associated with opening terminals in fullscreen, and another that could occur with superwide windows.
Which Situations the Notes Cover
The official 7.1.1 announcement ties the terminal crash specifically to fullscreen. That qualification matters if you are trying to match an earlier failure to the patch notes.
The other entry uses the term superwide windows. It does not give an aspect-ratio threshold or identify particular monitor models, so it should not be turned into a hardware compatibility list.

Hotfix 7.1.1 Scope
What the Hotfix Does Not Establish
Neither entry promises higher frame rates, a universal stutter fix, or an end to every crash. A failure that persists under different conditions needs its own description rather than being automatically classified as the same bug.
For returning players, 7.1.1 provides two concrete situations to revisit after updating. Record the display mode and the action immediately before any repeat crash; those details are more useful than assuming all stability problems share one cause.
