Gotta say, besides the mild slow-downs when traveling at full speed with the car through the world the streaming issue really isn't there otherwise. What I'm really amazed by is just how far they pushed the LODs and draw distances in this game, and given all that it's a miracle the issue isn't even worse. I mean I just think of how bad streaming stutters were in Fallen Order and this doesn't even register by comparison, and that wasn't even open world!
Tbh I think this might the game with the best LODs, it's absolutely spectacular and I just can't think of any other that comes close. The polish of the general graphical presentation of this game is up there with the best - impeccable. I really can't say enough good things about it (and the game as a whole), it's without a doubt the best Far Cry experience yet.
