Don´t work on Nvidia GTX 950 M, HELP

My Halo Wars 2 run so bad, i don´t know why!! I could play like HIGH resources on Blitz Beta!! And now i can´t play fine 2v2… on 3v3 my pc get broke! This is normal???
My laptop is a Toshiba Satellite P50-C-179
*Intel (R) Core ™ i7-6700HQ CPU @s.60GHz (8CPU,s), 2,6 GHz
*NVIDIA GeForce GTX 950M (GPU 4GB)
*RAM 8GB

Yeah I had this problem at first, too. You have to go into the Nvidia graphics panel and force it to use your dedicated GPU. Probably set to default integrated graphics. You may have to add it to the list if it isn’t there in the list of programs and games. Hope that works!

Thx for the answer mate. i don´t know how make this, i think how i can but Halo Wars 2 is not there to select and force it… i dont know how search the ejecutable to try it manual
:S
