Sandustry Crash and FPS Workarounds

DIRECT ANSWER

Start with the workaround that matches the symptom. For some crashes, try --sandustry-no-overlay-gpu-flags; for NVIDIA low FPS or broken Steam performance overlays, try --in-process-gpu; for severe fullscreen slowdown, turn Fullscreen off. These are developer-labeled potential workarounds, not guaranteed fixes, and some disable overlay behavior.

The developer does not guarantee any row. Record the result and undo changes that do not help.

E2 source: Official developer crash and FPS workarounds

Player question: A player needs the current developer workaround that matches a crash, low-FPS, fullscreen, overlay, or input symptom.

Change one variable, then compare

Launch flags and overlays can change more than one visible behavior. Apply only the row that matches the symptom, restart, and compare the same scene. If it does not help, remove the flag or restore the setting instead of stacking every workaround.

  • Steam: Properties → General → Launch Options for flags.
  • NVIDIA: turn off the in-game overlay for the crash comparison.
  • Fullscreen: Settings → Display → Fullscreen off.
  • Razer Cortex: disable its in-game/performance overlay and restart.

Preserve the documented side effects

The developer says --sandustry-no-overlay-gpu-flags may stop the Steam overlay while achievements should continue. The sources do not promise that --in-process-gpu improves every NVIDIA system, or that overlay software is the only cause.

Report the current build with its logs

Trace the answer before trusting it.

E1 is current first-party evidence. E2 is dated first-party or publisher-hosted reference material. E3 is timestamped public gameplay. Early Access updates can supersede any version-sensitive detail.

Publication limit: These are potential, reversible developer workarounds; hardware cause, success rate, universal fixes, and complete AMD/Linux behavior remain missing.
