Severe input lag with F-14 when force feedback on with MS Force Feedback 2 stick in use EDIT: Direct Input SOLUTION!

I think it depends on the module, but I'd say keep a copy of the .dll handy and just remember to try it if you run into input lag with any of your modules.  I ran into this issue with the MB-339, and the .dll linked above fixed it.
