FSXCENERY - KBHM BIRMINGHAM ALABAMA FSX P3D
This scenery and the same author's KRIC have the worst framerates of any scenery on my system. As a comparison I get better than 13fps with Flightbeam's KIAD and 1.5 to 2.0 with BHM in front of the GA Hangers. Additionally, the scenery and texture folders in both these airports have been full of the remnants of the scenery creation process to the tune of nearly 700 files. I think this author does nice looking scenery, but performance and trash in the installed product will prevent me from buying any more from FSXCENERY.
