### DRI3 GPU Acceleration

For accelerated apps or games, render devices can be mounted into the container and leveraged by applications using:

`--device /dev/dri:/dev/dri`

This feature only supports **Open Source** GPU drivers:

| Driver | Description |
| :----: | --- |
| Intel | i965 and i915 drivers for Intel iGPU chipsets |
| AMD | AMDGPU, Radeon, and ATI drivers for AMD dedicated or APU chipsets |
| NVIDIA | nouveau2 drivers only, closed source NVIDIA drivers lack DRI3 support |

The `DRINODE` environment variable can be used to point to a specific GPU.

DRI3 will work on aarch64 given the correct drivers are installed inside the container for your chipset.

**Note: Nvidia support is not available for Alpine-based images.**
