HDR support

[thomas7428]

Currently MagPie can not be used with HDR enabled content. I suppose that this is due to a lack of support from WinRT and GDI so it would be awesome to add the support of HDR to one of those. Cyberpunk 2077 with HDR (FSR and WinRT):

Cyberpunk 2077 without HDR (FSR and WinRT):

Vermintide 2 with auto HDR (windows 11 feature) (FSR and WinRT):

Magpie does not support HDR, and this feature may not be added for a long time.

As an alternative, Lossless Scaling on Steam has worked for me pretty well. Hope i'm not breaking any rules recommending an alternative considering the dev has said that support will not be added, and so the program is completely unusable for many people and games.

LS is a great program, I would recommend it if Magpie's FSR doesn't meet your needs.

Contributions are very welcome as my monitor doesn't support HDR.

I also don't have a HDR monitor, but I think it might be cool to add inverse-tonemapping methods if HDR was to be supported. This way you could play SDR games on HDR screens using Magpie. For instance, it is possible to train high quality inverse tonemapping neural networks.

I'm not familiar with HDR, but it would be really cool if Magpie could add HDR support for games that don't support it natively.

Apparently windows has Auto-HDR which automatically transforms SDR/LDR content into HDR content. I can't say how good it is though.

Autohdr hooks into the rendering pipeline to convert it (SpecialK is also another tool that can do the same) the games becoming legit native HDR then.

But even to do tonemapping yourself you'd have to somewhat tinker with the application process.. because in order not to have windows apply its own dumb one, I suppose the only way is to report to the system that the window is HDR-aware/ready.

No it doesn't. Auto HDR just takes the SDR output and uses an AI conversion to tonemap to HDR. It doesn't hook into the game any more than it needs to (which is, it needs to be DX11+ for the game window to output HDR). Technically Auto HDR could be activated system wide, but I guess Microsoft doesn't do that because they fear it won't look good in all games.

Damn, I always forget that, sorry. Anyhow, SpecialK still does what I said.

FYI, I found a useful article about Windows HDR standard and how to capture HDR content. high-dynamic-range/capturing-hdr-and-wcg-screen-content
