No. On first start the app checks your PC. With a suitable NVIDIA GPU (GeForce GTX 16 / RTX 20 series or newer, 6 GB+ of graphics memory, driver 570 or later) it installs the GPU version and uses GPU mode; otherwise CPU mode.
Both modes have the same features. GPU mode separates vocals with the high-quality models. CPU mode uses a fast model that takes about a minute per song; the backing track can keep a little of the original vocal. AMD and Intel graphics use CPU mode.
Switch between GPU and CPU mode in Settings (Import and playback quality). If the CPU version of the AI runtime is installed on a PC with a suitable NVIDIA GPU, choose Settings → “Reinstall the AI runtime…” and pick the GPU version.
