i am sorry it canot run on your pc but you see i do not think is is the graphics ithink its the very comlicated functions i use to run the game
(i can run it on my lenovo laptop it is high end tho)
1: foot ik and footlocking
2:AI behavuirs
3: the main character interacting with the world and ragdoll physics
but i will most likely see if i can make you request come to be
and i made it in Unreal engine 4 sooooo thats a lot of cpu and gpu
