To figure out, what limits your fps, there's a simple rule: if it's the hardware, the fps will not be stable. It will change, depending on the viewed map and position. If the fps is very stable (like constant 60 or 250 +-1), it's some kind of artificial limit - for example maxfps or vsync.

In your case, I'd check maxfps.
