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.
- Crash flag
- --sandustry-no-overlay-gpu-flags
- Low-FPS flag
- --in-process-gpu
- Escalation

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 |
|---|---|
| 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. v0.5.3 added diagnostics and published main.log paths for Windows, macOS, and Linux. The same note says a larger crash/problem patch was still being worked on, so resolution remains pending.
