Impact of STEAM launch option (-fileopenlog) to FFB

Today I installed a few skin mods (.pak files) from RaceDepartment and to use them I put -fileopenlog to STEAM launch option as instructed. When I launched the game I noticed something has happened to my FFB (using Thrustmaster T818 with Sparco Rally wheel) - FFB got stronger, so I had to decrease some sliders first, however my feeling is the FFB now is more precise, more natural, more real. I am pleased with this change. Have some of you experienced the same thing?
