GPU quick-check

Run this before installing. If GPU acceleration is needed:

Linux:

nvidia-smi

Look for CUDA Version: 12.6 or higher in the output header. If nvidia-smi is not found or shows a lower CUDA version, install or upgrade the NVIDIA driver.

Windows:

nvidia-smi

Or check: Device Manager → Display Adapters → right-click → Properties → Driver version.

GPU acceleration requires an NVIDIA GPU with Ampere architecture or newer (RTX 3000 series, A-series, or newer). Older cards (GTX 10xx, 20xx) do not support CUDA 12.6. AMD and Intel GPUs are not supported.

What you can do without a GPU

Everything except AI features works on CPU:

Feature	CPU	GPU required
Automatic color correction	✓
Noise reduction	✓
Sharpening	✓
Face detection	✓
Red-eye removal	✓
Classical upscaling	✓
AI Upscaling	Slow	✓ (recommended)
AI Artifact Removal	Slow	✓ (recommended)
Background Handling	Slow	✓ (recommended)

For testing AI features without a local GPU, use VIESUS Cloud — the GPU is hosted by Viesus AG.
