+### 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.
+
 ### Nvidia GPU Support
 
 **Note: Nvidia support is not available for Alpine-based images.**
