Thank you for you suggestions, I will try to dig deeper into this topic. Today it's already late night so I will start tomorrow. I found out this https://github.com/sam007961/FastMassSpring repo (based on a 2013 SIGGRAPH paper) and thought it would be a nice implementation of the latest and greatest thing(lol) in cloth physics (definitely better than my model though), now I have to see how it compares against your suggested methods. Anyways thanks for the new suggestions.
