8GB RAM, Nvidia GTX 940MX, intel core i7-6500U, any reply or help from you will be very appreciated (Sorry for bad english)

have u check your temps during gaming session?use msi afterburner to monitor your temps.

This is happening to me too on the same laptop.I don't know how to fix it. My temps go max 63 C then the pc it self underclocks the gpu so the temps won't go any further. Is this becouse of a bad cooling solution on the laptop or the softwere it self I don't know but that's the reason the fps drops accour ,but how to fix that I would like to find out for my self too.

You can try to change the link state management I think its called to off rather than maximum battery savings.
