[Edit] Sorry i wrote this after reading only the first page
Yeah, i noticed the poly count is very high on all of the models, for instance the railings - you seem to be using cylinders but unless the player is very close (almost first person) you probably wont be able to tell much difference between a cylinder with 20 sides and a cylinder with 3 (especialy once textured).

You shouldt be trying to lower the FPS, instead just try to get the best graphics at the highest FPS, and limit it to around 60 - this will allow it to run on lower spec machines than your own, anything over will be a bonus.
[edit] The FPS in the video seems very slow, but i assmue that just cos of the recording program right?
BTW, i wouldnt reccomend using a poly reduction program, it often screws up my models, i usually just redo the models completely.
