R6V on realistic setting shows how badly this game was made.

I´ve completed the sp campaign on "realistic" setting, and it was truly a boring and sad experience.
Here´s why.

9 out of 10 times you can´t shoot from around corners because of some obscure obstacle, due to bad layout.

Enemies spawn out of thin air.

The enemy can kill you with 1 shot from a shotgun 300 feet away.

Your teams AI is just too low, letting the enemy run straight by them without firing a single shot.

But most importantly, the game mechanics goes out the window on the "realistic" setting.

Breaching a room is impossible if there´s more than 1 enemy ( your teams AI is so bad that they´ll get killed seconds after they open the door )

All I found myself doing, was open the door and fire a few shots into the room. Making the bad guys run out to check whats happening.

Basically what I´m saying is, you can´t play Rainbow 6 Vegas on "realistic" as the game was meant to be played.

The sp was so bad, that it discouraged me from the mp.
