In its push for PC gaming being the champion of Windows, Microsoft won't be supporting HDR in Halo Wars 2 - while Mass Effect: Andromeda will (thanks, BioWare).
343 Industries Design Director, Clay Jensen, has confirmed that Halo Wars 2 will not have HDR support on the PC, but it will support 4K - which, in 2017 - all games should. Speaking with Fenix Bazaar, Jensen said: "I wish that I could say yes. Unfortunately, we are not going to have HDR support for Halo Wars 2. We do support 4K on PC, which looks gorgeous, and you definitely need to play that because it's stunning".
Halo Wars 2 could have HDR support post-launch, but it seems it won't be happening - Jensen adds: "It's something that, certainly in future titles, we'll be looking to support it. Unfortunately, not for this launch".
Halo Wars 2 launches on the PC and Xbox consoles on February 17, for those who buy the Ultimate Edition - and on February 21 for the normal version.
