I'm somewhere between a casual and hardcore for racing games. I have done a search of "logitech" and read through the posts about the logitech profiler for my DFGT. I need definitive information. As an example: Some posts say "yes, check that box".... other posts say "NO, don't check that box". It's a constant yes vs no in post after post. Is the profiler supposed to replace the game's ffb instructions? How does the profiler work? Can I edit the profiler ffb commands to get stronger ffb? Can I edit the games ffb commands in each game so I can get similar feel among the various games? Is the profiler supposed to add to the adjustments for the game's ffb instructions? I tried to test my first question: I closed the Logitech Profiler. I didn't minimize, I completely closed the program. The R3E ffb felt good, but the throttle and brakes were too sensitive. Even after changing the settings in the game. I only used 0 or 100 so I could feel what that particular setting does. So I opened the Logitech profiler. I follow this forums tutorials/fellow racer's settings. Create R3E profile. Used "options" to make sure it is using that profile and not the global default profile I UNcheck "allow game to make adjustments". Changed the accelerator and brake settings. Pedals feel great. Steering ffb still needed slight tweaks Then, I go into the r3e game settings and turn off all ffb in the game settings. Make sure my logitech profile is still selected and go back into the game. SUPPOSEDLY, I'm using the ffb settings from the Logitech Profiler. NO ffb at all in the game. What use is that check box "allow game to make adjustments"? I have spent days working with: F1 2011 (love the ffb) Dirt3 (love it) R3E (awesome steering feel - but setting up cars is time consuming) DTM Experience (same as R3E) GTR2 (same as R3E) F1 2012 (trash) F1 2014 (feel is between 2011 & 2012 - leaning more towards 2012.) Shift2 (trash) Grid2 (trash) Grid Autosport (steering feel is the worst of the group - but it's the only racing game that doesn't give me blurred vision) So - how is Logitech Profiler supposed to be used?
