Is this the first time you are running FTB on this laptop? And are you sure the laptop has a good dedicated video card, not only the integrated intel graphics?
If "no" for the second question, you may not have a video card powerful enough to run FTB at better framerates, sorry.
If both times "yes", you may have forgotten to make sure that FTB is actually displayed using the second, dedicated adapter. Sometimes, if the laptop does not choose the correct adapter by default, you will even have to add the "javaw.exe" (normally in: \program files\java\jre\bin) to the list of programmes that need to be run by the dedicated adapter (you do this via the video card's control panel applet).
