If you run WebNN on Intel GPUs with old driver versions between 31.0.101.5518 and 32.0.101.6083, the performance may not be good enough, because the DirectML execution of metacommands on these drivers is disabled by default due to some stability bugs. You can use `--disable_dml_meta_commands_for_gpu=0` to bypass. However, the functionality is not guaranteed.
