Noticed exactly same lack of FFB with G25, There is an edited effectsetup.xml file on the Steam forum and else where which improves things. Watched some Codemasters development vids and release day jitters vid this morning, they keep mentioning the good feel and you can tell difference between surfaces etc. I think they may have released old FFB files with the current version instead of the current ones in use by development, from there comments and descriptions of the feedback this seems most likely. With the wheel feedback we currently get, you may as well use an old non ffb wheel, which is what we used to play with years ago.
