Bad fps, any way to help?

can not get an fps above 30, no matter the settings i try, i can get an average 80-90 fps on the pre sequel, but on bl2 cant even hit 30. can someone please help with this?

my computer specs are strong enough to run this game on the highest setting, so its not my computers specs problem

Do you happen to have it capped at 30 by any chance?

What ghostie said. Also, telling us your computer specs / game graphic settings would help.
