Can’t trust Japanese devs to do the right thing.

if the HDR is easy to implement on the ps4 pro , then why there is still no HDR for games like the rise of tomb raider and the witcher 3 ?

@Nitro

It's not exactly automatic on PS4. The dev still has to set up the HDR profiles, as they aren't standard things you get from textures or shaders and it's handled on a rendering level. This is the case on both consoles. However, both system can use the same HDR profiles, as the profiles themselves are based off the HDR10 spec.

The automatic implementation as you mention it, is that no extra work is necessary on the PS4 once the profile has been set up, whereas, there are a couple extra steps on Xbox to tie in the HDR profile to the API code which handles it. It's not overly taxing to do, and mostly just means a few changes to ini type files, and of course the testing which is still done on both consoles regardless.

But I 100% agree with you that HDR has more effect on image quality on these systems than any of the snazzy power stuff that the systems allow. Plus, it's a great improvement which has practically no overhead in terms of system resources.

Assuming they did the low level code, it wouldn't matter if they used DX11 or DX12 on the system. Outside of the rendering pipeline having some changes, there is no significant difference between the two versions on the X1 or X1X, although X1X does do some of the DX12 specific code better, but no games out right now actually use any of those specific pieces of code yet that I'm aware of.

HDR implementation on UE4 has been available for PS4/PS4P since before the PS4P released. It wasn't released for UE4 until I think 2-3 months before the X1X released. This was more because the hardware specs and more importantly the API implementations for it weren't made available until then. Nothing Epic could have done until they had that. The update would be easy enough to implement in older versions of UE4, but depending on when code lock happened with the game, they may not have been able to implement it for the games release. That means it might be released a bit later.

@Rythmatic, and it also costs at least as much. What point do you think you're making?
