I don't have a player on my PC that will play this back. Even VLC will just display the first frame throughout :lol:
Can directly stream to my 4K screen no problem though, and it looks pretty neat!
The biggest thing that stands out for me is that white Porsche. There is a really nice contrast between the dark shadowed interior of cockpit, and the extreme white of the car. What's more, both the dark interior, and the white car retain detail in these contrasting areas. Really good footage, and the game looks quite nice as a result.
Imho, HDR > 4K. I can't say the resolution did anything special for me personally - Especially given how far away my screen is from where i sit.
