I have 2 objects, and I set one of them to boxes and another to polygons, or whatever.

If atleast one of the object's collisions are set to polygon, the framerate will slow down enormously.

Yet once none of them have polygon collision, the framerate is fine.

Anyway to increase the framerate with having polygon collision, other than "GET A NEW COMPUTER, DIPWAD" or something like that?

If framerate is a problem don't use polygon collision detection, dark basic has to check each and every triangle on your object for collision as opposed to checking just 12 triangles for a box collision.

As digital suggested you can use spherical maths to find the distance between two objects to determine if they collide or not, or you could stick with creating a collision box for each object.

If you really must use polygon collision then don't check for collision until both objects are within some distance of each other.
