I made a standart piece of Cloth with Apex via 3ds Max. No problems there. But the wind does not make me happy. Im using a Directional Wind source and tried pretty much every possible adjustment the Wind source gives me.
All it does is straighten my cloth. There are just no real Gusts of Wind. I do have enough Polys.
This is how it looks: http://gph.is/2rX58bQ
