How to Fish Performance & FPS Optimization Guide
Experiencing frame drops in heavy areas or stability hitches? Review our general performance suggestions, Steam Deck handheld advice, and stability troubleshooting steps.
General Graphics Optimization Suggestions
* Note: The full list of in-game adjustable graphics settings has not been officially published. The following are standard general recommendations to reduce rendering load:
Lower Resolution & Render Scale
If running on integrated or mid-range GPUs, dropping the rendering resolution provides the most immediate relief for frame rate stability during high-particle action.
Reduce Shadows & Water Reflections
Water physics and dynamic lighting in open-ocean crossings can be demanding. Lowering shadow fidelity and reflection effects generally improves frame pacing.
Disable Heavy Post-Processing
Disabling motion blur and heavy volumetric fog options helps maintain visual clarity when tracking aerial fish in mid-air trickshots.
Windowed / Borderless Display Mode
Switching between Fullscreen and Borderless Windowed mode can resolve alt-tabbing freezes and multi-monitor stutter issues on Windows systems.
How to Fish runs through Proton 9.0+ on SteamOS. While playable on handhelds, exact frame rates vary by hardware model, island zone, and player count (not officially benchmarked by this guide).
SteamOS Frame Limiter
If encountering frame fluctuations, capping the framerate via SteamOS Quick Access Menu helps stabilize frame delivery and manage power consumption.
Resolution & Scaling
Lowering internal resolution in handheld mode with system-level scaling enabled can smooth out heavier boss encounters.
System & Background App Tweaks
Disable Background Overlays
Discord Screen Share, GeForce Experience Instant Replay, and third-party recording overlays can introduce micro-stutters during rapid camera movement.
Install on an SSD
Island world streaming and fast boat travel benefit from fast storage drives. Installing on an SSD minimizes asset loading hitches.
Update GPU Drivers
Ensure you are running the latest GPU drivers from NVIDIA, AMD, or Intel to resolve early launch shader compiling stutter.
Players on Steam discussions have documented occasional game crashes and missing local save files after co-op disconnects. These are suspected stability bugs under developer review (not player error). Recommended protective measures:
Local Save Backups
Before major updates or joining public multiplayer lobbies, back up your local save directory:
%USERPROFILE%\AppData\LocalLow\Dazed Games\How to Fish\SavesSteam File Integrity Check
If the game crashes repeatedly upon loading an island: In Steam Library → Right-click How to Fish → Properties → Installed Files → "Verify integrity of game files".
Report persistent crash logs in the official Dazed Games Community Discord linked in Steam announcements (avoid sharing full saves in public channels).
