The white crush in 3D seems to be improves, now it does resolve up to 231-232, so it's not too bad, but still not as good as with 14.12. My only issue is that I get a crash of MPC-BE almost everytime the first time I launch a movie. Second time works fine. It appeared relatively recently but I haven't been able to trace which version of MadVR or MPC-BE introduced this. It could be a Crimson issue (but not 16.32 specific, I had it earlier), I still have to try to revert to 14.12 to see if it goes away, but as it means I'd lose 3D support with LAV/MadVR, which I really like, I'd rather try to find a solution. There is no error message or crash dump, so debugging isn't easy. Otherwise all seems fine.

BUT AMD Crimson enables my Crossfire when it detects MadVR (Wasting power on the 2nd GPU) unlike the old AMD CCC which it continues to use Single GPU only. So that being said it's another round of compromises but this time, I might stick on using the latest AMD Crimson since I get higher frame rates on my games. I wonder how it handles under Win.10, I heard scary stories on that Spying OS and the Last time I used it with MadVR It doesn't like Fullscreen Exclusive Mode and leads to dropped frames and CTD's |

Disable ITC and Enable GPU Scaling AMD Crimson
So I stumble about these 2 settings in AMD Crimson and I read about disabling ITC processing and enabling GPU Scaling bypasses the display processor entirely so ergo eliminating redundant conversions by the HDTV's processor since it was bypassed.
and also by doing this you're letting the GPU itself to do all the video processing and eliminating the HDTV to do redundant conversions, also it gives the fastest refresh and best fps in games when bypassing the display processor. |

Do you mean cadence detection? I see occasional cadence breaks with animated 3:2 content (Ren & Stimpy) but with movie content (Cronenberg's Crash), IVTC seems to work just fine, i.e. looks like cadence is consistently detected.

older driver than 14.something are always outputting 10 bit if the device supports that (and i haven't seen a TV that doesn't support 12 bit input) regardless of the input bit deep. which is hopefully just adding some 0 zeros and nothing else but you got an extra conversation step with older driver.

madshi, I don't know what algorithm you used to remap the HDR content to SDR but according to the ST.2084 standard everything under 100nit should be exactly the same as in the SDR.
Do you think it is the right time to discuss light output, gamma curves remapping, color space remapping, etc?

I'm sure he has read the appropriate specifications.

Well, I am sure too, but It does not look like the content below 100nit keeps the same light output level, it changes with the "HDR Peak Luminance" setting in madVR.
I don't doubt madshi's decisions about the remapping algorithm for a second, that is why I asked if it is the right time to talk about the whole HDR to SDR remapping issue so that madshi will be open to suggestions.

Just judge if it looks good - which it certainly does. PS: I don't see anything concerning "content below 100nits" in SMPTE ST 2084 in any case. Its literally just an equation to convert non-linear (gamma) to linear.

I'm really excited about the recent 3D/MVC developments! Huge thank you to Madshi and Nevcairiel. The only problem I seem to have is that subtitles are not rendered with depth. Source is 3D Blu-ray. Playing the disc with TMT6 results in the subtitles being displayed with varying amounts of (usually negative) parallax. With MadVR subtitles are always at the screen plane. I'm currently using MadVR 0.90.15 and Lav 0.68.0-2.

Just a quick reply to this. I'll reply to the other posts in detail in the next 2 days.

I compared madVR's current super-xbr implementation with Shiandow's latest for MPDN.
Images with 200% super-xbr scaling: madVR: Shiandow's: When watched very closely or with some magnification, madVR shows less aliasing. But I guess this is due to the tweaked parameters by Hilian, and not because of his improved anti-ringing filter. I think there's not such a case where the anti-ringing filter would remove actual details in a crucial way. I'd really like to see how the improved deband filter behaves without the other tweaked parameters. Then we'd know for sure. |

Yes, the new params slightly add aliasing. Madshi already had spot that when I showed to him and that's the reason he didn't incorporate in madVR.
Other than that, I think the new params improves in fine details, like pixel art, subtitles, etc. If Shiandow prefer to get rid of all aliasing, he can reverse the changes or add then as an option. |
