Aerosoft Skavsta p3d problems

Hello all,

Not sure wether this is the right place but okay ​

Just "installed" Aerosofts skavsta into p3d (via the "here is the scenery files p3d, LOOK AT IT" way, which usually works great). BUt when I landed, I noticed how bumpy it was, and seeing as this isn't xplane, it was the bumpmap of landing on dirt. My 737 was very hard to get moving due to it.
anyone else with ti​ps or advice? Checked vector but to no avail.
