Hi. I can't change resolution and someone know how to fix this problem ? In this picture rendering mode is not triple screen but i choose it and have the same thing.

Are you using a purchased copy of Assetto Corsa? I can see from your screenshot that the career mode tab is shaded out, and that you have many graphical settings that have been changed in 1.0RC.
Steam should have automatically updated your game for you when the updates are released.
Updating it via steam should be sufficient!
