Played the demo for an hour or so. I think it will be a really good game, but if that's the campaign mode its really lacking. I'm really pumped about VR portion though
I'm on ps4 pro with HDR. Visually, its really mixed. In replays, menus, and under certain conditions, it looks great, better than anything else to me, but unfortunately, not during gameplay. The pics I saw on Neogaf had me excited until I realized most were cherry-picked. 3 of courses I played are downright average looking, very bland and could have been something from Forza 4, but higher resolution. Framerate seems butter smooth.
The lighting looks great on the cars, but very "artificial" other times. The taillights/headlamps have a cool HDR effect, but they "outshine" the other visuals, making them look worse and stand out more.
I've give the demo an 8/10 overall. Great gameplay, mixed visuals from excellent to very average/below.
