Sandustry Crash and FPS Workarounds
DIRECT ANSWER
Update to v0.5.5 first: it replaces instructional videos with animated images to address preview-related GPU crashes and expands crash logging. If the problem persists, use only the developer-listed workaround that matches the symptom, such as --sandustry-no-overlay-gpu-flags or --in-process-gpu. These remain potential workarounds, not guaranteed fixes.

SYMPTOM ROUTER / POTENTIAL ONLY
Choose one reversible comparison
The developer does not guarantee any row. Record the result and undo changes that do not help.
| Observed symptom | Developer-listed comparison |
|---|---|
| Preview-hover GPU crash / OBS hook loss | Update to v0.5.5; instructional videos were replaced with animated images. |
| Some launch crashes | Try --sandustry-no-overlay-gpu-flags; Steam overlay may stop, while achievements should continue. |
| NVIDIA crash | Disable the NVIDIA in-game overlay. |
| NVIDIA low FPS / overlay monitor issue | Try --in-process-gpu. |
| Severe fullscreen slowdown | Settings → Display → Fullscreen off. |
| Graphics-software crash | Close AMD Gaming Evolved, NVIDIA App, or NVIDIA Control Panel; Profile Inspector users can try a new default profile. |
| Razer input stops | Disable Razer Cortex in-game/performance overlay, then restart. |
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
Use Esc → Send Feedback → bug report → Submit when the problem persists. v0.5.5 expanded main.log diagnostics for Windows, macOS, and Linux. It also added optional Crashpad diagnostics that players can enable after the developer requests a dump and explains that it may contain sensitive information. The update fixes named crash paths, not every hardware or overlay failure.
