This hook uses [DetectGPU by @TimvanScherpenzeel](https://github.com/TimvanScherpenzeel/detect-gpu), wrapped into suspense, to determine what tier should be assigned to the user's GPU.

👉 This hook CAN be used outside the @react-three/fiber `Canvas`.

```jsx
function App() {
  const GPUTier = useDetectGPU()
  // show a fallback for mobile or lowest tier GPUs
  return (
    {(GPUTier.tier === "0" || GPUTier.isMobile) ? <Fallback /> : <Canvas>...</Canvas>

<Suspense fallback={null}>
  <App />
```
