Curves on hardware doesn't work

[LunaMoo]

Game or games this happens in

games using curves like easily accessible Loco Roco for example

What area of the game / PPSSPP

Neither "hardware tesselation" nor Low quality curves do anything. Only Medium and High which to my memory are the only two running on the cpu, seems to work. Seems to affect all backends, tested on clean build of the v1.16.6-478-gc220199d8 changing only mentioned settings and trying out different backends.

What should happen

I think I'll just close it as I'm unsure if it's really not working. I just can't see a difference between low and medium anymore and this is most likely from the #11425 I can't really reliably test performance difference on my hardware and quality they're the exact same for me.

Edit:
I managed to find a game where there was a noticeable difference in quality between low and medium so guess it works(curvy roads in Juiced 2), also I remember trying hardware tesselation after the above was merged and it was still buggy which was another thing making me think it doesn't work, but I suspect now that it was buggy on my older system where I had GTX 1060 with 7 and later windows 10 while it looks ok currently with RTX 3060 ti + win 11, possibly was affected by a driver issue as other people also saw those bugs with different gpu's.
