After the patch update, I am missing some options which I could use with my steering wheel before the patch. So here are the issues: Can't adjust wheel range in steering settings. Now I have to use the Logitech Profiler for this. Maximum value for steering lock for GTR 3 cars now only 20, before was 40. I can't find Brake vibrations option in Force Feedback Settings, really miss that one.
Had the same problem - took me 2 hours to sort out. Uninstall your Logitech Gaming Software completely and reboot, get the 5.10.127 version of LGS from here: http://support.logitech.com/pl_pl/software/lgs (64-bit if you run 64-bit OS). Install the software, let it detect your wheel etc. Reboot again. Now it should work. As for brake vibration, I think they are gone in favour of the new slip effect.
