Which Video Driver For Dedicated Only In Optimus Setup

Evening all. Just after some general advice. I have just installed Manjaro XFCE as I’m sick of windows.

The laptop I am using has nVidia Optimus with an nVidia Geforce GT 630M.
Before anyone points out the obvious. Yes, I know this is a POS.

In windows, I switched to only use the dedicated GPU.
When I installed Manjaro, I chose proprietary drivers. Everything is buttery smooth in xfce.
However, I seem to have taken a considerable downgrade in game performance. I’m not expecting miracles, just wondering what is the best option.

In the Manjaro Settings Manager GUI under the Hardware Configuration. I have a tick next to “video-hybrid-intel-nvidia-390xx-bumblebee”
And next to “video-nvidia-390xx” I have no tick.

Then under 3rd Gen Core processor Graphics Controller, “video-hybrid-intel-nvidia-390xx-bumblebee” is also ticked.

If I am wanting to force it to only use the dedicated GPU, should I install “video-nvidia-390xx” ?

Thanks a lot for any pointers!
