Question as heading.
Can you run the 8k at 5k without the extra sampling ?
No
there is a limit on the transmitted image, only 8K x may display the image as is
Good question…but NO !!!
What you’re asking is effectively if you could trade field of view for resolution (in pixels per degree, not total pixels). This would be theoretically possible if the display panel supported a region of interest type update, and the firmware could configure the scaler to use it, neither of which I find very likely. It’s not an advertised feature nor has it been presented as a development goal, as far as I know. Typically low latency video scalers (and high latency ones with full frame buffers are way too much latency for VR use) cannot handle drastically different scan rates, so if they did support it at that layer only it would probably have to be attached at a specific edge of the panel, and that would make them effectively different directions. This is a niche request which is likely hard to solve. I do find the concept interesting. For instance, imagine having your VR character put reading glasses on, or a set of binoculars, and having it switch to a higher precision mode.
Not quite that technical. I just was wondering if it could be run scaled back. Same fov, just at less resolution.
I’m getting the 5k anyway and won’t be giving up my early bird spot for a 8k but the thought crossed my mind.

Technically 8k runs in 5k resolution (2.5k per eye) and scaling it to fit all the physical pixels. Scaling is done via headset hardware, so it’s not exactly same as supersampling, as it doesnt increases hardware requirements for your pc.
Basically you wouldn’t want to disable the scaler and use lower input, it doesnt makes much sense.
p.s. 8kx is not only one who runs native, 5k does it too. However there is still no confirmation if it’s possible to run these headsets in lower resolution, but for sure you can reduce overall load by lowering ‘supersampling’ slider (in pimax software, steamvr slider most likely wont work).
So is brain warp included in the 5k as well?
All headsets support brainwarp (on a paper)
