I checked on by one, and now I know that the problem is from Nvidia-GPU.

either :
1. the battery charger that come with the laptop doesn't provide enough power to it? (or not stable and cause directx stop)
2. The graphic card is too heat? (but unlikely, because even in standard setting that I can run by intel chip alone, it still has directX problem)
3. 540M not support this game yet! And may need more driver update later. But if this is the case, other laptop with 540M should have the same problem with me. (Please help me if anybody also use laptop with 540M)
4. My graphic card has some problem physically. may be it is bad product from factory and I should claim it. (I will try to claim it by this reason if I m sure that it is not 3 reasons above.)


because my laptop spec is so high that I could run FF14 in normal resolution with core-i7 alone. (Turn off nvidia to save energy mode) Now I notice no directX problem at all after I change to use CPU only. Now, if anybody would be so kind to help me think which of the choices above was the cause of problem from the Nividia card ? because I prefer use the 540M and have little higher setting in FF14.
