I have some similar specs in my laptop (except the gpu XD), which are:
Intel i5-4210U @1.7GHz 2.4GHz
Nvidia GT 840M
8 GB DDR3 RAM
With these I can play perfetcly at 1080p and even with more enhancements like MSAA. But I have one trick: If you play in Exclusive Fullscreen mode and (while Wind Waker is running) you open your Graphics settings; it somehow gives you a boost in performance. I think that it is because it resets the graphics configuration.
I hope it could help you!
