It's a crossgen game, not a next gen only game. You may have prefered another artstyle, but it does great the artstyle they choosed. And also performs great even in PS4 and potato pcs.
The only thing you could criticize of these visuals is that you'd personally -af it's my case- have prefered a different artstyle.
Basically all of them say that it's an excellent game in all areas and both for unskilled newbies and seasoned hardcore competitive players.
The only exception being the -optional- rpg lite story tutorial extra bonus mode, which is enterely optional. They say it isn't as polished as the rest of the game but still a great addition specially for casual rookies.
World Tour runs in the demo and benchmark works well on my GTX1070 laptop.
Maybe there's some bug specific of their hardware or some area of the game, or they made a terrible choice with their settings, or they had a potato PC older than mine. If it's a bug, let's hope they hopefully in the day one patch.
