I don't see the point. (Call of Duty: Warzone)

Recently played with a friend in a Warzone, while I haven't installed the new driver from Nvidia (451.48), and each set. He still stood the same settings as me, but there was a visible difference in the rendering, the texture quality etc. are Now updating the drivers for my graphics got worse, I decided to put about high settings, but for some reason everything remained the same. I have one such problem?
