I've read many posts about mirrors don't showing cars. I've had this problem too and the reason of my problem was the high lod mod. See my explanation below. "The files that destroyd my mirrors were the files from : F1 2012 Ultra High LOD&Settings MOD by Acura When I copied this files : generics_highLOD.pssg, generics_livery.pssg and generics_lowLOD.pssg from his mod to Program Files\Steam\steamapps\common\f1 2012\cars\generics My mirrors stop working. This mod will make the tyres on ai cars look the same and as good as on the players car." So any with the mirrors problem and this mod installed, just copy the original files i noticed above ,back to the Program Files\Steam\steamapps\common\f1 2012\cars\generics And the mirrors are working as they should.
