1. GPU & Graphics Adapter Configuration
A DirectX 12-compatible NVIDIA, AMD, or Intel GPU (including Intel UHD, Iris Xe, and Arc) is recommended for faster processing through DirectML. If DirectML cannot run the model, Pixel Up automatically retries on CPU. CPU processing can take several minutes for larger images.
- Auto Mode (Recommended): PixelUp automatically detects and prioritizes your high-performance dedicated GPU when multiple adapters are present.
- GPU Driver Resets: If your graphics driver encounters a reset during intensive operations, PixelUp automatically reduces tile size and re-initializes sessions. If GPU device errors persist, the app safely falls back to CPU execution.
- Driver Updates: Ensure your graphics drivers are current from NVIDIA, AMD, or Intel.
2. Memory & Image Size Handling
Memory requirements depend on the source image dimensions and selected scale. PixelUp checks available memory before processing very large images.
- Before decoding pixels, PixelUp probes image dimensions from file headers to estimate peak memory usage.
- If the estimate exceeds physical memory thresholds or single-array caps (~2.1 GB limit), PixelUp issues a preflight notification to prevent application crashes or system instability.
- Tip: If you encounter memory notifications on very high-resolution originals, process images in smaller batches or select 2× scaling.
3. AI Models & Storage
Pixel Up includes its Upscale and Remove Background models with the application. Allow storage space for the application, its included AI models, and exported images.
- The Real-ESRGAN Upscale models and the BEN2 background-removal model are included with the application.
- Image processing does not require a runtime model download and runs locally on your PC.
- Internet is still required for Microsoft Store installation or updates and for Pro checkout, activation, and periodic license validation.
