My mistake : wasn't thinking of the subd in VWD but subd in Poser or Daz!

So If I have a clothe that is far under the memory limit, I can try a subdivision in DS to have a better simulation result? My idea is the rise the definition of old clothes with subd (in DS). For example if the simulation for one clothe subdivision level 1 with dist min to 0.5 is better than the same clothe subdivision level 2 with dist min to 0.9. Let's stay at subd level 1
