I had an issue with my G25 initially, as well.

In the windows settings for it (under control panel->game controllers), it defaults to only 270 degrees of rotation and a combined throttle/brake axis.

Needless to say, those were NOT conducive to proper driving!

Welcome to S2. The AI are not the best mate (to say the least)...get yourself online so you can at least get spun out by real life batards

I don't trust my driving enough to go online yet. My plan is to work through the training, and when I can at least get an "okay" on all the S1 stuff, I'll wade online.

I still have issues with early apexing

Hola, just got a G25 not a week ago, didn't like the rFactor demo that came with it, downloaded LFS and just unlocked S2 last night.

I've done some performance driving in real life, just did my first track day a few weeks ago, have discovered I'm not as good of a driver as I liked to think, lol.

Still getting beat up pretty bad by basic AI, usually by getting spun out by the baards.
