+If both variables point to the same device, the container will automatically enable **Zero Copy** encoding, significantly reducing CPU usage and latency. If they are set to different devices one will be used for **Rendering** and one for **Encoding** with a cpu readback.

+You can also use the environment variable `AUTO_GPU=true`, with this set the first card detected in the container (IE `/dev/dri/renderD128`) will be used and configured for **Zero Copy**.

-2. **Kernel Parameter:** Set `nvidia-drm.modeset=1` in your host bootloader (GRUB/systemd-boot).

+2. **Kernel Parameter:** You must set `nvidia-drm.modeset=1 nvidia_drm.fbdev=1` in your host bootloader.
