I've been meaning to ask you about F1 as I'm tempted but heard it's bug-laden. Was maybe thinking of holding off for F1 2011. What do you think?
To be honest I dont think the DFGT is such a step down from the G27 in GT5. Your wheel is a) officially supported, b) has the adjustment dial on wheel, c) can remap buttons and d) still has the full 900 degree turning. I miss out on the support but I guess the pedals are nicer and the wheel is (supposedly) quieter. The G27 is a luxury for me TBH but with xmas and bday so close together I managed to fiddle one

As for the clutch and H gate I only have GT5 to use it on

But I can report both work fine. I dont use the clutch but depending on the car I'm in I switch between that and flappy paddles just to make it a bit more realistic.
Do you use the in car view by the way? Now I;ve got a proper setup I'm only using in car + manual gears.
Also in steering options did you set it to standard, pro or sim? I set it to pro but for now have left ABS and stuff default.
