Explore All PEAK Troubleshooting Tips If PEAK launches to a black screen but you can hear audio or move your mouse, the issue is typically tied to incorrect fullscreen settings or corrupted display data. Here’s how to resolve it and get back into gameplay.

Investigate Resolution or Fullscreen Glitches

The game might be attempting to run in a resolution your display doesn’t support.

Solution:

• Right-click PEAK in Steam
• Go to Properties, then Launch Options
• Enter:
  -screen-fullscreen 0 -screen-width 1920 -screen-height 1080
• Launch the game
• If the screen remains black, press Alt Enter to toggle windowed mode

Clear Display Settings from Registry

Unity-based games save screen configurations in the Windows registry. Corrupted entries can cause black screens.

Solution:

• Press Windows Key R, type regedit, then press Enter
• Navigate to:
  HKEY_CURRENT_USER\SOFTWARE\Landcrab\Peak
• Remove any entries beginning with Screenmanager
• Restart Steam and try launching PEAK again

Change Rendering API: DX12 vs Vulkan

Some users experience black screens with only one graphics API active.

Solution:

• In Steam Launch Options, add either -force-vulkan or -force-d3d12
• If Vulkan leads to instability, use DirectX12 with the windowed launch fix instead

Update Graphics Drivers

This issue frequently affects older GPUs like the AMD Radeon HD 7000 series. Keeping drivers current is crucial.

Solution:

• Visit AMD or Nvidia’s official website
• Download the latest driver for your graphics card
• Reboot your system and relaunch PEAK

Turn Off Overlays and Running Background Apps

Applications such as Discord, GeForce Experience, MSI Afterburner, or Steam’s overlay may interfere with the game’s display output.

Solution:

• Disable all overlays (Steam, Discord, etc.)
• Close unnecessary background programs before starting the game

Launch in Windowed Mode

Fullscreen mode may trigger the black screen—bypass it by forcing a windowed start.

Solution:

• In Launch Options, input:
  -popupwindow -screen-fullscreen 0
• This often avoids compatibility issues with certain monitors

Consider a Performance Optimization Tool (Optional)

If the game struggles to start or experiences crashes, tools like LagoFast can help improve launch stability and system performance.

Final Notes

Black screens in PEAK are commonly due to resolution mismatches or outdated GPU drivers. The fix is usually straightforward—use launch parameters, reset registry settings, and ensure your drivers are up to date. And just to clarify—changing your monitor won’t solve this. We tested it.

Frequently Asked Questions

Q: Why can I hear the game and move my mouse, but the screen stays black?

The game is running in an invisible fullscreen mode that your monitor can't render properly.

Q: Can switching to Vulkan resolve the black screen?

It might work for some, but Vulkan can also cause crashes. Using DirectX12 with windowed mode is generally more stable.

Q: Is a low-end GPU the root of the problem?

Not always, but older AMD cards like the HD 7000 series are more prone to issues with PEAK.

Q: Will reinstalling the game fix the black screen?

Only if you also clear registry and driver settings. Reinstalling alone usually doesn’t solve the problem.

Q: Can third-party overlays actually crash the game?

Yes. Overlays from Steam, Discord, and others are known to cause display issues in Unity games, including black screens.
