| This means the system will primarily use `card1` and then fall back to `card0` if needed. | ||

||
| `AQ_NO_ATOMIC` -> Disables atomic mode setting for the DRM. | ||
| Atomic mode setting is a feature that makes screen updates more reliable by grouping changes together. |

this should not be encouraged whatsoever as legacy drm support is... poor in aq
|
|
||
| `AQ_MGPU_NO_EXPLICIT` -> Disables explicit synchronization between buffers when using multiple GPUs (multi-GPU setups). | ||
| Without explicit syncing, the system handles buffer transfers between GPUs more automatically, | ||
| which can improve performance in some cases but might introduce errors in more complex setups. |

implicit sync is less peformant

| `AQ_DRM_DEVICES` -> This option allows you to set a specific list of DRM devices (GPUs) for the system to use. | ||
| The list is separated by colons (:), and the first device listed will be the primary GPU. | ||
| For example: `/dev/dri/card1:/dev/dri/card0`. | ||
| This means the system will primarily use `card1` and then fall back to `card0` if needed. |

May be good to add a part here about symlinking to ~/.config/hypr/card. There was a good section about that in the pre-aq docs.
