NvTrueHDR - RTX HDR in games (testers needed!) #120
Comments
Can't seem to get this working at all. Both with the tool and via NVProfileInpsector with your XML. I tried with Fortnite DX12, Dolphin Emulator DX12, and Yuzu VK with the DXGI Swapchain setting enabled. What does the HUD element look like? Also does NVCP show it as active because that is a good way to check if it's working for videos it changes live. |
After a DDU it works finally. I have no clue what caused it to break since I had default NVCP settings |
Hm, maybe try using the full path for the EXE, might be needed for profiles added in NVCP. If it still doesn't work try using NV inspector with the XML on nexusmods. @CeIIHunter I had same issue when trying to work out how to enable it, almost thought it was just broken & gave up on it till I did a clean install lol, glad you could get it working. Not sure which NVCP settings might be interfering with it, think I did have DXGI swapchain setting changed too, maybe that's the cause? |
Adding the entire path worked, I did a quick test and it looked great. |
@Artins90 I imagine this game is using RT and or DLSS? I believe Nvidia's HDR uses tensor cores so if a game doesn't make use of those cores there shouldn't be performance loss? Also yeah it looks great when compared to AutoHDR, a little dimmer than I'd like, but it seems like it uses a wider color gamut more appropriately. |
Also @emoose I don't know if the DXGI swapchain causes it. I reenabled it after getting it working and it seems to function still. I'll update if it breaks after a reboot or something. |
It's Granblue Fantasy: Relink, it doesn't support DLSS nor raytracing. |
just can't get it to work on any game i try. win10, latest driver fresh after ddu, aw3423dw. tried disabling all overlays(steam, nv, rtss) but nothing |
doom 2016 with vk is the only one that sorta worked so far, but performance is horrific at around 2100ms per frame, starting it with opengl just doesn't do anything like with other games |
I posted a quick TrueHDRTweaks tool at https://www.nexusmods.com/site/mods/781?tab=files to let you tweak some of the hardcoded values, haven't been able to figure out what they all are yet though, if anyone feels brave feel free to give it a try.
Not really sure if it works on win10 unfortunately, seen a couple win10 users mention it not working at least... are there any Win10 users here that have it working? E: yeah looks like the driver is checking for WDDM 3.1 for some reason, not sure if Win10 ever included that, might be Win11 only :/ |
I have tested all values exposed by your ASI loader and written down what they do. Paper white multiplier is Value5 and it defaults to ~203 nits, which is more appropriate than what AutoHDR default to at its minimum brightness (~300 nits or so, too bright for a dark room).

Is it possible to expose the tweaks of TrueHDRTweaks tool for videos as well -normal RTX HDR Video? Would be great to control how youtube and other streaming videos in browser will look! Oh, and this works beautifully in games particularly after the tweaks, many, many thanks! |
So I can't figure out why but with Vulkan FPS either dies or it works it seems inconsistent for me for some reason. Have not gotten it working in OGL at all yet. |
v0.5 of the tweaks seems to apply to MPC-HC fine with the RTX video renderer, haven't tried it in browsers at all though, would guess the ASI loader might be able to load it into them but wouldn't be surprised if something might break it, if anyone tries it let us know how it went. (0.5 also added a bunch of extra unidentified settings, one of them seems to have a pretty big effect on FPS, feel free to give them a try) |
@CeIIHunter Have you gotten NvTrueHDR to work with Yuzu? |
Nope never got it working. But we got the new driver update and nvidia app that lets you enable it. That'll probably work but currently it only supports one monitor. The NVTrueRTX still works with dual monitors so I'm still forcing it that way lmao. Thanks nvidia |
Noticed that nvapi64 exposed some TrueHDR profile settings a couple drivers ago but they never seemed to have any effect, when 551.23 released I did see the driver DLLs were trying to read from them now though, but settings still didn't seem to do much...
Digging around in the driver it turned out there were some other undocumented settings it needed enabled too, with those set it seems to activate fine 😺
Posted a tool that can set up the settings for you here: https://www.nexusmods.com/site/mods/781
Sadly haven't found a good way to take screenshots of the RTX HDR yet, but to me it seems to give slightly darker results than Windows AutoHDR, maybe preferable to some.
Only really tested this on my own system so far, would be interested in hearing any feedback from anyone who tries it!
