Makes it dead easy to switch between the 2 games so wont screw up being able to drive GTR.
Yup. I went from GTL to GTR last night without missing a beat
If I spend any time with any other sim, it completely screws up my GTR for 4-5 laps until I get used to it again
I think it's got quite a bit to do with the force feedback effects, that familiarity is common between the two games and I'm guessing that you use it quite a bit subconsciously to make continuous minor adjustments and that's the bit that can feel so different thus making switching sims quite difficult (for me at least).
Pops.
