Hello,sorry for resurrecting a 5 days thread,
I firstly tried Reflections Subway on my Nexus 5.Cooking process took ~30 minutes.Considering your post,your pc have to have really low hardware considering it took hours and hours to cook content? My spec is Lenovo y580 with GTX 660M and i7 3630QM 8gb ram which is very very old and I bought this laptop like 2,5 years ago.I think 3 hours is a lot for cooking basic template project there must be others thing wrong maybe ?
