Without commenting on story:
- The specs required for the game are insane. I have a 1070ti + i78700k and I can only do 1080p 60fps on highest settings. That's pretty sad for a port of a two year old game. To use the high-res textures you tell you that you need a 1080ti plus an 8700k, so basically, you need to have one of the best possible specs money can buy before getting into Titan X shit.
- They really don't want you turning the screen filtering off(It's a shitty blur filter to improve performance for consoles) In the demo, you could turn it to off and the image was much sharper. In the full game it's now just "low".
- I haven't run into any expanded story content yet, nor have I played the DLCs. I mostly got this because they're adding in Offroading with the car, the boat, and changing some of the combat. So far though, everything is exactly the same. Hmm.
