AoE2 HD Forgotten Kingdoms is so laggy its unplayable for me

I'm not the best with computers at all. I don't have a gaming pc, i have a laptop that's 1.5 years old now. I've always run Rome Total War II smoothly without trouble though, so i thought AoE2 (being a much smaller and older game, with less impressive graphics) would run without problems, would be fine. I literally see 2 frames per second and it's unplayable like this. Is it my PC? do i need to reinstall? The normal vanilla AoE 2 i have works perfectly fine, why is this version suddenly so slow? Is there anything i can do to fix this?

​

thanks in advance
