Game crashing and launching problems are unfortunately very common in modern PC gaming, and while they are not always possible to completely fix, there are usually several reliable steps you can take that dramatically reduce the problems. If your computer meets the game’s requirements and isn’t running into serious hardware shortcomings, this guide will walk you through the best methods for fixing crashing and launch issues in Abyssus.

Takeaways:

  1. Learn how to fix Abyssus launch and crashing issues.
  2. What keeps causing Abyssus to crash on Windows?

How to Fix Abyssus Crashing or Not Launching

Before doing anything else. Make sure your system BIOS and Windows are fully up to date. Then, clean-install your GPU drivers using Display Driver Uninstaller (DDU).

  • Download Display Driver Uninstaller (DDU).
  • Download the recommended stable NVIDIA driver (for example, from December 2024).
  • Disconnect from the internet.
  • Run DDU to fully uninstall your graphics drivers.
  • Reboot your PC.
  • Install the older driver manually.
  • Reboot again before reconnecting to the internet.

Verify Abyssus Game Files

Corrupted or missing files can prevent Abyssus from starting.

  • Steam: Right-click Abyssus in your Library > Properties > Installed Files > Verify Integrity.
  • Ubisoft Connect: Open the game page > three dots menu > Manage > Verify files.

Use Lossless Scaling (It works really well)

One of the most effective workarounds for crashing issues linked to performance is Lossless Scaling. This is a third-party application available on Steam that uses frame generation and smoothing techniques to make gameplay appear much smoother. So if your computer can't quite run the game stably, you can run it at a way lower graphics setting and use Lossless Scaling to boost things. Thus increasing stability and reducing crashing issues.

Here’s how to set it up:

  • Purchase and install Lossless Scaling from Steam.
  • Launch the app alongside Abyssus.
  • In the Lossless Scaling options, choose LSFG 3.1 (Frame Generation).
  • Set the scaling mode to “None” if you’re not trying to scale the resolution. Though I suggest using scaling, so set it to "FSR" or "LS1".
  • Once Abyssus is running and you are playing, press Ctrl + Alt + S to turn on Lossless Scaling.

Repair Visual C++ Runtimes

The game requires Microsoft Visual C++ libraries, which may be missing or damaged.

  • Go to the game’s installation folder > Support > Redist > VCRedist.
  • Run the installers for Visual C++ 2010, 2012, and 2015–2022.
  • Choose Repair (or Install if not present).

Alternatively, download and install an all-in-one Visual C++ package.

Disable Steam Beta

Experimental Steam client builds can cause instability.

  • In Steam, go to Settings > Interface.
  • Under Client Beta Participation, select No beta chosen.
  • Restart Steam.

Disable Third-Party Overlays

Overlays often conflict with games. Disable the following before launching Abyssus:

  • Discord Overlay
  • MSI Afterburner / RivaTuner
  • NVIDIA GeForce Experience Overlay
  • Steam Overlay
  • Restart your system after disabling them.

Avoid Alt+Tab During Startup

Switching windows while the game initialises may cause crashes. Wait until the main menu loads before using Alt+Tab.

Reset Game Settings

Corrupted configuration files can block the game from launching.

  • Open Documents > My Games > Abyssus.
  • Find the folder linked to your Steam or Ubisoft ID.
  • Delete GameSettings.ini.

The file will regenerate on launch with default settings.

Set DirectX Mode Manually

Some systems handle DirectX differently. Try forcing a version:

  • Right-click the game in Steam > Properties > Launch Options, then enter:

-dx11 for older or mid-range systems
-dx12 for newer GPUs

You can also remove DirectX arguments entirely to let the game decide automatically.
