Why? On the other side I've tried dxva2 copy back but... With uhd 24fps films I've to lower ngu up scaling to "sharp low quality". With uhd 60fps demo clip I forcely need to use d3d11 decoding to have no dropped frames. |

For people with NVIDIA & HDR who have a way to test what the TV is receiving (with diag dongle or light meter), did you try changing the "SDR brightness" slider in Windows Settings to see if that changed the bogus metadata being sent to the TV?
It may be a bug with Windows making everything go through the SDR-to-HDR convertor. Edit: another test: try playing some HDR file with Windows' own Movies & TV app to see if the metadata being sent is different from when using madVR. If yes, then MS may have added some HDR API available from UWP apps but not from Win32?

I thought madshi said he wasn't developing for os-hdr.

madshi's response in that nVidia thread is troubling. If there's no "windows api for hdr" that he can call to enable/disable hdr and nVidia removes their deprecated api that's going to leave us in quite a bind when it comes to new drivers. Awesome....sigh

It may or may not be going away but it's definitely not working as we'd want it, really just looks like it merely hands HDR control over to Windows.
The good news is, 398.11 seems to work perfect. Custom res works great too. I haven't tested anything after this, but apparently this is the last driver that doesn't have this bogus metadata issue. |

Even if the MS HDR API doesn't have a "toggle" function (I didn't check), informing windows about the wanted HDR metadata might still be quite reasonable.

That's a good point. Windows might internally decide "uh, hey, that looks like HDR maybe I should turn that on". Then again, it might just ignore it until the user enables it in the CP. One never knows with windows. The one thing we DO know about windows is that it's not likely to be consistent between versions.

Thanks j82k for doing the measurements. Feel much happier and more confident that I downgraded.
I used to be a pure dedicated media guy since 2008/09. Prior to the Popcorn Hour I was so frustrated in using a HTPC for media playback. But MadVR's tempted me back into the HTPC game again. And this reminds me why I went to a dedicated player - it's a minefield of compatibility issues. I downgraded to the correct drivers for HDR passthrough but that broke CUDA playback as I was getting macro blocking. Eventually figured out I had to switch to DXVA Copy back but in the middle of a movie which I was looking forward to and never ended up finishing. Instead I shouted at the computer haha. On the positives I fixed the HDR tone mapping on the OLED, got Rec2020 output in SDR for my RS49 though. I'm planning on creating a "production/live" system which I will use as a dedicated HTPC. I won't apply any software/driver updates to avoid this situation happening again. But I'm sure Win 10 will get very upset and try and install updates behind my back. |

This latest HDR metadata issue has also freaked me out as it was not really mentioned when everyone talks about the latest driver still allows passthrough etc, but it has obviously raised its head again and has been broken for months, you then find out your life has been a lie for all this time. |

Recalibration also takes forever.. Wish there was a faster probe than i1displaypro that I can afford.

Simple things like Text looking terrible and general DPI issues made me rethink in no time and back to Windows 10, for all of W10 faults sometimes when you do go and revisit an OS, you remember that it was not as good as you remember especially with advances in 4K displays and the like. |

On a projector though it's a huge difference ofc. I successfully watched a movie just now, looked amazing and very happy MadVR works. Now do I try and tweak the dropping frames every 4.73mins or do I just leave alone before I break something else |
