Tessellation for new planetary tech, or too much for VR?

Last night I discovered that the PC version of No Man’s Sky had tessellation for planetary surfaces introduced in the Next update, but it was disabled by default. Having since enabled it I’m very impressed by how much better planets look (though it obviously still needs work, with the occasional surface pop-up evident, hence why it was disabled I assume).

ED’s planetary surfaces look very obviously flat in VR, though the textures are good and shadows on flat rocks work correctly etc. Looking at the (now delayed) ice planet render goal for Q4 it seems to me that tessellation might be incoming for us, but I’m worried at how much a performance impact it will have and thus not viable for VR.

Although I’ve quite a healthy VR library I don’t have any games that feature tessellation to my knowledge. Anyone out there have any ideas on the performance cost and whatnot? Will I be left looking at a GTX 2080ti order page with a single manly tear rolling down my cheek?
 
Early on in Horizons the balance of detail was much more heavily shifted in favor of geometry over textures. However this caused serious performance issues, so they toned down the geometry while increasing the texture detail to compensate. Was a pretty good compromise, IMO (it nearly doubled my surface frame rates on moderately high-end hardware of the day, if I recall correctly), but I can definitely see how it would be lackluster in VR.

I would like the option for better surface geometry, but I'd expect to pay a high cost for it in terms of framerate.
 
Here's a video of tessellation on and off. It makes the surface a lot more detailed. It's almost a night and day difference.

We're still driving around on barren airless worlds while NMS has all these lush planets with alien flora and fauna... Frontier really should speed up development and release major surface detail improvements.

Tessellation would really help with the fine details. That is, if you put your nose to the ground you would be able to tell individual specks of dust and their dimensions.
