Multiple rendering scales to increase FPS

Can multiple rendering scales be implemented?

I often fly B747 in VR mode.
That experience is extremely realistic and fun!

In doing so, I drop the rendering scale to 70 in order to increase the FPS.
The visibility of the main panels such as the PFD is significantly reduced, but I have no complaints at all about the resolution of the scenery outside the windows and the 3D cockpit.
Especially for the scenery outside the window, it looks good even with the render scale set to 50.

View outside the window = Render Scale 50
3D cockpit = render scale 70
Main panel (PFD/ND/FMC) = Render Scale 100

As mentioned above, I would like to see the implementation of the ability to set any rendering scale for each layer.

Thank you.
