As a G29 user having replaced my G27 I wish i could use the H-pattern gearshift in GT6 to bide my time for GT Sport but yes it is recognised as a DFGT in settings menus. For me at least, it's always more fun, engaging and satisfying to use the 6-speed gearbox instead of the paddle shifters, especially when driving the Lotus 97T around the Nurburgring. I doubt PD will release a patch for full G29 configuration but I'd be overjoyed if they did.
