Just absolute retard levels of Detail! And all geometry too.
The site is bad as a Library, so I rebuild it into a well managed structure.

Included thumbnails and dimensions file for quick look through and grab. Included quick 3dsMax tutorial for .stl files.
Nice result. I used to use Autodesk 123d Catch for photogrametry, but lately their service greatly degraded. I think i have to try something else. How much time it takes for average i7 to calculate points and to build mesh for such relatively simple object like your example?
I tried 123d Catch some years ago, but the experience is meh. You don't exactly have means to correct errors and it resulted in much post time needed in 3dsMax. Nothing compares to the quality of Photoscan and the price seems fair.
My rig has a fx 8350 and a gtx 770. So I'm just below the power of an i7, yet point generation on max quality is ~20-25 minutes, but it can be scaled down to 10 without perceived loss in quality. The graphics card only speeds up a single operation: Depth calculation, but surprisingly halfs the time during that phase.
Mesh building takes another 15 minutes.
Mesh building nom noms the most RAM, but I never broke my 16gb limit and always on highest quality.
Obviously I did 30cm models and it was not room scale, so your mileage may vary. To that comes ~5-10 minutes of cleaning the point cloud by hand, so that the mesh is not messed up, as cleaning the point cloud is vastly easier than cleaning a mesh. And lastly 30secs for 4k textures.
Be aware though, that the models have dirty geometry and aweful UVs, even with well chosen projection settings. It works great for still renders and adjusting texture color and contrast. But if you wanna draw textures by hand you will have to UV unwrap, which with the messy geometry can be quite the hassle. But for Wood kitty and the ceiling relief, just perfect.
PS: used the free APP xNormal to bake displacement and normal map.
edit: Makes me remember The game: the vanishing of Ethan carter, where the dev basicly Photogrammetried the whole game.
