Does a 4k monitor drag down VR in P3D?

[glider1 90]

In P3D using VR you need an external monitor connected. Do you think that connecting a 4K monitor means the GPU has to work harder rendering to it as well as the headset? If you switch the monitor to 1K resolution is the GPU actually only processing 1K worth of pixels which leaves more headroom for the VR headset or is it still processing 4K worth of pixels internally?

Thanks

Good question I would say turning down to 1k would reduce GPU overhead

But if you use a VR headset all visuals are displayed in it. What need or use is there for a monitor that we don't look at ?

It's only 8 million more pixels being refreshed 30, 60 or more times per second. It's going to have some effect on performance. 🤔

I don't think it is a big deal because the resolution of the simulator is reduced to matcher the VR googles.

Exactly. The need for the monitor shows that the way VR is implemented is still primitive. I think P3D uses one because it maps the position of the mouse in VR to where it is on the external monitor. I wonder if MSFS will also need to render to an external monitor when they introduce VR? Hope not.
