With all med settings in P3d 4.3, I'm getting an avg of 8-10 on the ground. As soon as I take off, fps improves to 25-30 in the surrounding area. 

If you uninstall KBWI and try it with default, what are your frames?  There has to be something else going on with your system as I get near zero performance hit with the new KBWI.  Are you running any vector programs?

Update - performance has improved a bit after the following:

1. Update latest Orbx Libraries - just released. Apparently, this has been overdue and potentially causing issues in other areas

2. I completely shut down Windows Defender, which was running scans in the background. I did have all the sim folders excluded, but nonetheless, this caused some drop in frames

To me, it's still not where it should be. After takeoff from KBWI, frames right away improves to 25-30. Doing a short VFR flight in the area, performance is fine, until very close to the ground, landing at KBWI again - I can watch the frames drop dramatically to about 14-16 as I touchdown. 

Other vector - I do have Black Marble Vector. I do not own Orbx Vector.

How many roads do you have enabled? To test, I would try with this completely disabled or reduce road types as this program is hard on performance and BWI is a vector heavy area.
