Frequently Asked Questions (FAQ)

Answers to common questions about hardware requirements, GPU acceleration, fixing Whisper hallucinations, translation errors, and licensing.

Hardware & GPU Acceleration

Q1: What are the system requirements? Can I run V2sub without an NVIDIA GPU?

OS: Windows 10/11 (64-bit) or macOS (Apple Silicon M1/M2/M3/M4).
GPU: NVIDIA GPUs (GTX 1060 4GB+, RTX 3060 8GB+ recommended) automatically enable CUDA hardware acceleration.
CPU-Only PCs: Works great on CPU-only laptops! Use the small or medium model and enable Full-Speed CPU Mode in Config → Model Config for a 30%–50% speed boost.

Q2: How do I verify if CUDA GPU acceleration is active?

Open Help → System Check inside V2sub 2.0. If GPU acceleration shows as unsupported on an NVIDIA card, update your driver from the official NVIDIA website and restart your PC.
