First of all , happy holidays!
Now , polygons on screen is a very vague statistic if you relate it to frames per second. You could have 70 000 polygons of static data without a bone structure and animations , no movement (hence the static description). This might bring you a full 60+ fps.
Now add characters with double-digit bone structure , move them around , manipulate the bones and geometry in real time (a.k.a play animation) , apply shaders , use lights and shadows and you get a mix of heavy processes impacting your framerate. The less polygons on the scene , the less processing work per cycle , the faster the game runs (or is capable to if frame rate is capped).
Or it could just be your PC specs
