I see what you mean. I was talking about elasticity, because it surely being reduced judging by the video, making a cloth look less realistic.
I thought that was what they meant by stretchiness, maybe i was wrong.

It says “it reduces stretchiness” I believe that was about over-stretchiness typical for hi-res cloth in PBD (right pic) so reducing that is not bad

It says “it reduces stretchiness”. While nature of the cloth is to be elastic enough to not produce that many wrinkles. It’s well shown in this video.

article itself tells that those wrinkles reduce the ‘realistic’ feel
Where ?
I only see notices like coarse meshes that are typically used in games today do not show small scale detail making the cloth look stiff and unrealistic and that wrinkle mesh add those missing details without reducing performance significantly

More wrinkles -> less resilience for a cloth, and then it doesn’t look like a cloth anymore
In case of high-triangles count ? yeah, it looks more like thin rubber – but I don’t think anyone will use 100k+ in real games
Main point – less physical mesh resolution with same visual look (like 2k -> 10k) And it will also keep cloth from stretching to much.
