Thank you!

Thanks - I could do that, but so far I've only the one and it is not that great of a movie. I presume however the "better" option will be to use the HRD->SDR conversion option that is currently being work on (when it is ready) for all HDR content?

you could pickup an RX 460 for about 60, you'll get NGU sharp low around 30ms rendering, that What I was getting prior.

EDIT pretty sure its HDMI 1.4 spec, unless there was a late HDMI 2.0 version?
Right thanks, but even a RX580 isn't all that faster than my o/c 7850(basically as fast as a 7870): http://gpu.userbenchmark.com/Compare...870/3923vs2161

only +54% in some benchmarks and apparently Polaris doesn't like NGU huh, I got all bells and whistles enabled(SSIM 2D, ED2, NGU, Luma & Chroma SuperRes) with my 7850 @1080p so I guess I'll have to throttle it all down a good bit for 2160p and even a RX580 wouldn't quite be the savior either as it would appear.

Apparently Club 3D make dongles that convert DP to HDMI 2.0 allowing 2160p60 on any semi-recent AMD so that's another option, hopefully hiccup-free

Which NGU? I prefer NGU Anti Aliasing for <SD.

Yes.. This is exactly the use case for NGU AA. You don't use normal or sharp NGU on resolutions that low.
Also you'll need to pay particular attention to your screen and madvr sharpness settings.

NGU sharp is known to show significant problems with flawed low res images like DVDs.
using RCA and add grain can help a lot.

shaders are done on the GPU is should work with all decoding types.

When it's ready, for sure.

What subtitle renderer are you using? The function doesn't work with subtitle filters that render on the video themselves ((xy-)vsfilter), only with those that use a separate subtitle interface (MPC-HC ISR, XySubFilter, AssFilter(Mod)).

Had a play with the test builds over at AVS. Looks good though the rendering overhead of HDR-->SDR seems to much for my 1070 on UHD HDR 59.94 content. Can't get the render times down under the required 16ms for 59.94 content (all high 20ms+) regardless of the Chroma scaling used. Unless you have any ideas of combos that work with a 1070 it looks like a 1080/1180 will be the next purchase.

You need profiles to use less power with UHD @ 50/60p, for example with bilinear chroma etc. It should be just doable. Certainly not a problem for the 1080ti.

FYIW - I tried all the Chroma scaling options including bilinear - all in the 20ms+ on the 1070.

EDIT: Depending on the HDR-> SDR Settings (like using Clipping) you can almost get away with no drops on bilinear....

What test builds?

I'm stuck with an older version of MadVR because the newer ones don't work with UHD BD menus with Jriver media center.

Is this a closed thing? Or can I also try newer builds here?

The test builds are for HDR tonemapping improvements, ain't gonna fix your problem. Just wait.

The fixes for the issue with BD Menus sometimes being off the screen is fixed in the test builds. Still it is best to wait till a new version is out and is packaged with JRiver.

Are the rendering stats now accurate, for those of us who have seen them drop after the last Windows Update?

I see it drops two times. One is after update to Windows 10 1803 ,
another one is after update to the latest Nvidia Driver.
Now on my PC for none OC GTX1060
23.975fps with smooth motion
720p->1440p
chroma> NGU AA (low) +RCA (for free)
luma> NGU sharp (very high)
chroma> NGU sharp(med)
the rendering time is around 6.2ms.

I don't why if I turn on the showadvancestep then the rendering time would be increased.
