Troubleshooting How to Fish
A reversible troubleshooting checklist for How to Fish launch failures, low performance, controller problems and online co-op issues.
Do not delete saves, configuration folders or cloud data until you have made a backup and exhausted reversible checks.
Game does not launch
- Restart Steam and the PC.
- Install pending Windows and graphics-driver updates.
- Use Steam’s installed-files verification.
- Close overlays and monitoring tools temporarily.
- Check security software history rather than disabling protection permanently.
- Confirm the computer meets the 64-bit Windows 10+, 8 GB RAM and supported GPU-class requirements.
Low frame rate or stutter
Close background applications, reduce resolution and expensive effects, and test the same area again. If performance improves in single-player but not online, separate network symptoms from rendering symptoms. A low-end system with exactly 8 GB RAM benefits from keeping browsers and launchers closed.
Controller is not detected
Reconnect it before launch, remove duplicate devices, verify Steam recognizes the controller, and compare Steam Input enabled versus disabled. Restore the official layout before testing community mappings. Steam confirms full controller support and specific PlayStation controller support, so a persistent failure should be reported with the device model and connection type.
Co-op connection fails
Make sure the group is within the one-to-four-player limit, all copies are updated, and the host can create a fresh lobby. Switch host once, restart routers only if other network checks fail, and inspect current Steam service status or the community hub for a widespread incident.
How to write a useful bug report
- Game version and date observed.
- Windows version, CPU, RAM and GPU.
- Single-player or online co-op.
- Exact steps that reproduce the problem.
- Expected result and actual result.
