That guy post is 1 year old so I don't think that he will answer
Laptops usually have bad graphic cards in them and are not too good for gaming. Thats might be your issue. Just try to download newest drivers for your graphic card. If that doesn't help I would suggest that you create topic on HoN forums in tech support. You should get much better help there with HoN
PS. What graphic card exactly you have in your laptop?
