## RTX 5000 Series (Blackwell GPUs)

Due to upstream framework limitations, GPU acceleration for built-in OCR

(PaddleOCR / MangaOCR) is not yet available on RTX 5000 series GPUs.

### Recommended setup:

• OCR Device → CPU
• Translation Device → CPU
• Use Ollama for GPU-accelerated translation (recommended)
• Or use OpenRouter (cloud) as an alternative provider  

Ollama uses its own runtime and works correctly on RTX 5000 GPUs.

OpenRouter runs in the cloud and does not rely on your GPU.

## Non-ASCII Windows Usernames (Cyrillic, Arabic, etc.)

Thaluna now automatically detects non-ASCII usernames and switches to:

C:\Users\Public\Thaluna

No manual action is required.

---

Installation Path (Important)

Do not install or run Thaluna from folders containing special or non-English characters (e.g. "Téléchargements", "Pobrane", names with accents).

This can prevent bundled models from loading correctly and may cause the application to fail on startup.

Recommended:

Use a simple path such as: C:\Thaluna or D:\Apps\Thaluna\

## Diagnostics

If you experience crashes or OCR issues:

• Use the **Diagnostic build**
• Attach console output or logs when reporting issues
