While the game is slightly demanding, it's not all that.

What are your system specs?

Yes tell us your computer specs, will be easier to tell what is wrong.
Btw this game despite the age, uses full real time per-pixel lighting (the lighting is not baked), old or not that is still a heavy rasterization effect even today.
Of course it also depends on the computer running the game, personally I can play this on a RX 6700 10GB at 4k max settings and this is far from a high end GPU, but I wouldn't be surprised that even some modern, relative cheap non-gaming laptops, will suffer with this game.
