i rented this out the other day and im glad i rented cause this is not worth paying for, however the full version will definitely be worth every penny. The graphics are just amazing sometimes, and the physics have been greatly improved since gt4 but i wouldnt say theyre realistic. It works good with the G25, but using the controller feels weird, feels like theyve put some smoothing on it, which kind of helps but makes it hard to catch slides and you end up with the back swinging like a pendulum. And i still cant do proper burnouts/donuts, which means something in the physics code is still very very wrong.
