GPU UUID is a unique identifier baked into your video card by NVIDIA or AMD at the driver level. Unlike MAC or volume ID, it's part of the card itself — replacing the GPU is the only way to truly change it.
But GPU UUID is exposed through user-mode APIs (DXGI, NVAPI, WMI) and that's where our changer intervenes. We rewrite the cache and intercept queries so the visible UUID looks different to the OS.
An anti-cheat that uses GPU UUID purely as a software signal sees the new value and accepts it. An anti-cheat that goes deeper (D3D12 device LUID, hardware DRM contexts) requires a more aggressive approach — supported in our v3.0+.
Important: physical GPU UUID change is impossible without flashing the BIOS, which voids the warranty and can brick the card. We always operate at user level — safely and reversibly.
