Hi !
I tried it today (I was with another version) and I will not write about physics but It exists some huge issues with the sounds.
Inside, It could be OK (but I heard something like two mixed sounds which have some "battles" between them to get the leadership !) and the exterior sounds are barely completely broken (crackle sounds, mute sometimes, far..!) in replay.
I was thinking about a track issue (tested with the last version of Road Atlanta) but NO, I tried on a vanilla one (Brands-Hatch) and It stills the big issues I heard before.
I have no much time for trying a swap with another engine sound which could be OK, I'm sorry.
Did someone got this issue too !?
Cheers !
