I would advise any nvidia user not using a 900 series card to force physx to CPU in the nvidia control panel as long as your cpu isnt to ancient.. PhysX seems to be hurting performance quite a bit when its accelerated through the GPU. The video i posted earlier have been updated and its no longer necessary at all to delete anything. Exceptions are if you already have a gpu set as a dedicated physX card but not many do these days then you dont need to do a thing at all.
