📢Update Announcement: Bug Fixes & Optimization

03/03/2026 · Patch Notes · DEAD END COLOSSEUM

Hello everyone,

Thank you for your continuous support and feedback.
We have recently optimized several issues and addressed reported bugs. Below are the details of this update:

✨Key Optimizations & New Support

- Enhanced HDR Support: We have adjusted the game’s engine to better support HDR displays. If your monitor and system have HDR enabled, the game will now provide a better dynamic range.

Localization Fixes:

- Fixed issues where Korean/Japanese text was mixed, and Korean text appeared in the English version.

- Corrected various typos and grammatical errors.

- Fixed text box overflow issues to ensure dialogue displays correctly.

- Korean Version Image Loading Error: Resolved the filename mismatch issue that caused certain images to fail to load.

đź› Gameplay Bug Fixes

- Outfit State Fix: Fixed an issue where Lurie’s outfit state did not reset correctly under specific conditions.

- System Correction: Fixed bugs related to "Slave Mode."

⚠️Known Issues & Developer Notes

- Steam Deck / Linux Freezing Issues: Due to current development environment limitations, we are unable to perform full testing or technical intervention for Linux/Proton. Therefore, compatibility issues for these platforms are currently on hold.

- Dialogue Skip Function: We have received requests for a "Skip" feature. However, implementing this would require a major overhaul of the game's core architecture. Due to high technical difficulty, this feature is currently not planned for implementation.

- Endless Mode: This feature has been added to our evaluation list for future consideration.

đź’»PC Troubleshooting
If you experience graphical glitches, a black screen, or the game runs poorly, please try the following solutions:

1. Update Graphics Drivers

Ensure your graphics drivers (NVIDIA / AMD) are up to date.

- Non-Dedicated GPU Users: Even if your device uses Integrated Graphics (iGPU), updating Intel or AMD integrated graphics drivers can often resolve launch issues.

2. Force "High Performance" GPU (Fix for Black Screen/Lag)

If your hardware meets the requirements but you still face issues, manually assign the GPU:

(a) Access Settings: Right-click on your desktop → Select \[Display settings].

(b) Open Graphics Options:

Windows 10: Scroll down and click \[Graphics settings].

Windows 11: Click \[Graphics] under Related settings.

(c) Add Game: Under "Custom options for apps" or "Add an app," click \[Browse].

(d) Select Executable: Navigate to your game folder and select the Game Executable (.exe).

(e) Set Preference: Find the game in the list, click \[Options], select \[High performance], and click Save.

(f) Restart: Close and restart the game to apply changes.

3. Check Monitor Connection (Desktop Users)

Ensure your monitor cable is plugged directly into the Graphics Card (GPU), not the motherboard.

- Multi-monitor Users: If one screen is connected to the motherboard, it may hinder overall performance. Ensure all monitors are connected to the GPU.

4. Special Notes for Laptop Users

- Power Mode: If set to "Power Saving," the system may disable the dedicated GPU. Please switch your Power Plan to \[Best performance].

- GPU Allocation: Laptops may default to integrated graphics due to system errors. If Step 2 fails, ensure your system isn't restricting GPU usage.

5. System Resource Check

Ensure you have sufficient RAM. Running multiple high-load programs simultaneously may cause texture loading failures or crashes.
