Just tried it.
It's screamer 4x4 with better graphics and physics (I'm not entirely sure about the physics though). Not many steering wheels are supported. No Fanatec, no Thrustmaster, no G27. There is support for the G25 which is probably the same as having support for the G27.
If you go off track or off a cliff, you car will be reset on the track, similar to an arcade game.
Probably no damage ==> visual as mechanical.
As I never used screamer 4x4, I still have the game and I never use it. I will not make the same mistake when I bought screamer 4x4 and will not buy this one either.
The menu is in Russian, so I can't comment on options etc... .
