Would you say the G25 will not work properly if I don't install the profiler? For me, the G25 is working fine. No problems with regard to steering or setup, even in other games. And I do use the drivers from the official Logitech site. They include the Profiler if I'm not mistaken, but I just extract the drivers and use those in my unattended Windows installations.
The wheel is correctly recognized as a 'Logitech G25 Racing Wheel USB'. And I can calibrate through the Game Controlers in the Control Panel, and test all the 19 buttons. I was hoping there was a setting in a config file that would control the ratio of turn for the cockpit wheel. For me this is just a small issue and not worth installing the Profiler for.
Thanks all for your suggestions.
Kind regards,
Willem
