Thank you, gentlemen!
Sgt Cunnings was right... that’s an RHS optional feature and I could change it in the mod menu. Much better now!
@PFC Price, found that possibility too (ranges were 6000, 8000 and 12000m), but, as you said it yourself, it doesn’t solved the bad resolution in the scope, and also, the leaning problem. Best was to unmark that RHS option
Appreciate for the help!
