In Falsus Black Screen on Launch: How to Fix It

If In Falsus opens to a black screen — music playing or not — you are not alone. It is one of the most-reported launch problems in the Steam community hub since the demo went live, and in most cases players report getting in-game again within a few minutes. Work through the fixes below in order; each one has resolved the issue for someone, and the early ones are the fastest.

There is also a purple-screen variant that Chinese players have reported （社区里有人叫它「神秘紫屏BUG」). Everything in this guide applies to that too — treat the purple screen as the same class of problem: the game window renders, but the output is broken.

1. Update your GPU drivers

An out-of-date graphics driver is the single most common cause of a black screen at launch in new indie releases. Download the latest driver directly from NVIDIA, AMD, or Intel rather than relying on Windows Update, which often lags several releases behind. Reboot after installing, then try the game again before moving on.

2. Toggle fullscreen and windowed mode

If the game launches but shows nothing, press Alt+Enter to force a switch between fullscreen and windowed mode. Players report this working when the game is trying to render in a fullscreen resolution or refresh rate your monitor cannot display — a situation that commonly produces exactly this "launch to black screen" symptom, especially on multi-monitor or high-refresh setups.

If Alt+Enter does nothing, try launching with the game window minimized and then restore it, or check whether the game is rendering on a monitor that is turned off or disconnected.

3. Verify the game files on Steam

A corrupted or incomplete download can leave the engine starting but unable to load its rendering assets:

1. Right-click In Falsus in your Steam library.
2. Choose Properties → Installed Files.
3. Click Verify integrity of game files.

Steam will re-download anything that is missing or damaged. This is quick, safe, and worth doing before any of the more destructive steps below.

4. Reset the game's config files

A stale configuration file — one that stores an invalid resolution or a display mode your system no longer supports — survives reinstalls because it usually lives outside the game folder. Look for the game's config or save directory under your user folders (check AppData\LocalLow, AppData\Roaming, or Documents for a folder named after the game or the developer), and rename or delete the config files inside. The game will regenerate them with defaults on the next launch.

Renaming instead of deleting keeps a backup in case you want to restore your settings. If you are unsure which folder is safe to touch, ask in the Steam discussions before deleting anything.

5. Disable overlays and background recorders

Third-party overlays hook into the rendering pipeline and are a classic cause of launch-time black screens. Players report conflicts from:

• Steam overlay — toggle it off per-game via Properties → Enable the Steam Overlay while in-game.
• Discord overlay — Settings → Game Overlay.
• NVIDIA GeForce Experience / AMD overlay / Xbox Game Bar — disable their in-game overlay features temporarily.
• Screen recorders and FPS counters (OBS, MSI Afterburner/RivaTuner, Overwolf) — close them completely for a test launch.

If the game works with everything disabled, re-enable overlays one at a time to find the culprit.

About the purple screen

The purple-screen bug reported by Chinese players appears to behave like the black-screen issue from the same launch era: the window opens, the game may even be running behind it, but the frame output is corrupted. No official root cause has been confirmed. Community reports point to the same suspects — driver state, display mode, and overlay hooks — so apply the steps above in the same order. If your screen is purple specifically, start with the Alt+Enter fullscreen toggle and the config reset, since those target display-mode mismatches most directly.

Still stuck?

If none of this helps, your report matters: search the In Falsus Steam community discussions for existing black-screen and purple-screen threads, and add your hardware (GPU, driver version, monitor setup) plus what you already tried. The developers read the hub, and detailed reports are what turn into patches.
