RTX HDR mod + Lossles Scaling

[Grabuge]

Hello!
First thanks for this amazing piece of software and really good job on the last update, tried it a little and it seems flawless now!
Really love it but Nvidia now released RTX HDR recently and an universal mod for games was made out of it : https://www.nexusmods.com/site/mods/781

I can't get both of them to work together or decide myself wich one to keep... Is there a way?

So if anyone can help in this regard, thanks

I will try to resize too again, but if i remember well, already tried without success.
I will try THIS SPECIFIC GAME also.

the HDR mod don't even work in this game on my side.
Are you sure you'r not mistaking something? You sure you seeing HDR content?
Are you using AUTO HDR maybe? you have to disable this one to use the mod.

it would be so cool to have both together!

I'm using Auto HDR and since I'm using a QD-OLED monitor the only way I could tell the HDR is working without an indicator is if I see a very bright white screen lol

Ok i've got a case with both working together: in Yuzu Emulator.
-DXGI LSFG without other scaling and HDR Support ON

Please if there is a way to prevent Lossless Scaling to shut it down in "regular" games, it would be awesome.

Also, the HDR mod specify this in case (i've done it) :

-VK/OGL games might need the "Vulkan/OpenGL present method" setting in NVCP changed to "Prefer layered on DXGI swapchain" for it to activate properly

It is now not only just a mod, but and official nvidia feature!
You need latest driver i think + this : https://www.nvidia.com/fr-fr/software/nvidia-app/
but still no luck outside of yuzu sadly

I just got it working with the RTX HDR mod, try changing the Capture API on Lossless Scaling to WGC and make sure HDR support is turned off under Rendering

This appears to be working for me. Not sure exactly what is doing the trick because I brute forced, I have it set to use RTX HDR in the new Nvidia app, I used the NVTrueHDR tool on the .exe, as well as added it to AutoHDRForce in case Windows AutoHDR works on it. But regardless I am testing in Gmod at the moment and I can see the difference. This is actually preferable to using RTX Auto HDR in the game in fullscreen since the HUD is unusable at 4K and RTX Auto HDR won't work in tandom with Nvidia image scaling. 1080p through this looks nice and sharp and you can still add HDR to older titles, very neat

I tried it with Factorio and turning lossless scaling on turns rtx HDR off, but it doesn't turn it off in Yuzu.

I'm dealing with this exact issue right now. From my testing, it seems like RTX HDR and Lossless Scaling running together break when it is a DirectX game. I have not tested against DX9, but this is my experience for DX11 and DX12. The reason why it works in Yuzu is because the emulator runs with Vulkan. All Vulkan run games work with RTX HDR and LS together.

I managed to combine rtx hdr and lossless scaling together in kingdom come deliverance today.
You need to use NV true hdr mod and select lossless scaling as path, open game in borderless, go to lossless scaling, turn HDR support OFF and select WGC not DXGI
Works perfect after, no issues with color

Thank you for this tip! I tested with a different game, but it worked perfectly for me.

How do you get it to work? I downloaded NVTrueHDR but I cannot add Lossless Scaling as path. This shows:

---------------------
Enter app executable name (use "base" for base/global profile)
> "C:\Program Files (x86)\Steam\steamapps\common\Lossless Scaling\LosslessScaling.exe"

Fetching settings for app 'C:\Program Files (x86)\Steam\steamapps\common\Lossless Scaling\LosslessScaling.exe'...
Failed to locate app profile for 'C:\Program Files (x86)\Steam\steamapps\common\Lossless Scaling\LosslessScaling.exe'
Try adding it in NVIDIA Control Panel & retry with the full EXE path.

Press enter to exit...
--------------------------------

pls help

I did exactly what it said and added Lossless Scaling through the NVidia control panel. Open the control panel, go to Manage 3D Settings -> Program Settings and click the Add button. Add Lossless Scaling and then when you put it through NVTrueHDR again, it should work.
