2d cloth solver very very slow

[steve3d]

So to do 19 frames took over 10 mins.

I then tried switching off CUDA and the result was pretty much instant. Problem is now though that I'm getting cloth mesh intersection issues. I turned on CUDA again and turned off self collisions which is what seems to be what is causing the massive computational times.

I obviously need self collisions so not sure what to do from here? This type of solution seems unusable right now.
