+CARLA is also partially supported, though the performance is not great. It needs to be manually installed with:
+
+```bash
+poetry install --with=carla

+openpilot doesn't have any extreme hardware requirements, however CARLA requires an NVIDIA graphics card and is very resource-intensive and may not run smoothly on your system.
 For this case, we have the simulator in low quality by default.
 
 You can also check out the [CARLA python documentation](https://carla.readthedocs.io/en/latest/python_api/) to find more parameters to tune that might increase performance on your system.
