G27 have destkop profiler software, g29 doesn't. They are not identical completely.
I suspected it was software related but was not aware there was no desktop profiler for the 29/920. That's a huge miss by Logitech, who just a few years ago claimed they were getting out of the gaming peripheral device business altogether. Seems to me with that decision it means that they were targeting the wheels for the consoles first and PCs as secondary afterthought.
But hardware wise, according to a review I read last fall that included a tear-down, the 27 and 29/920 share the same internal components. That's all I was referring to. The only difference of course being the rim itself. I wonder if someone will step up and crack the 27 profiler software to make it compatible with the new wheels.
As I did with the G27, I use the desktop profiler for my T300 as the primary settings (degrees rotation, FFB feel, etc.) and then scale those settings up or down in the game itself depending on the type of car I'm racing. Saving different desktop profiler settings depending on the game is a huge plus too. Very disappointing to hear.
