My screenshots were created with the jpg source file that I shared with you. I have tried resetting the settings earlier too and even now. I get the same result. As I mentioned in my screenshots, I was using Catmull Rom AR LL for downscaling and not SSIM clean AR LL. Interestingly, I just tried SSIM clean AR LL with the jpg file and I got a reddish image (this didn’t happen with any of the videos that I played).
Please see the two downscaled images from the below link: I have kept the OSD on for both – one is with CR AR LL and other with SSIM clean AR LL downscaling. Both the screenshots were taken using 0.90.7 build after reset of the settings, only the downscaling algo was changed. http://www.mediafire.com/download/2g...fter_Reset.rar Incidentally, even in your downscaled image, the edges of melons are not that smooth as you get with 0.90.4 build. Also you have taken a smaller downscaling factor. I think the above screenshots with the OSD will make things more clear. |

The edges are not as smooth because you've used Catmull-Rom while I've used SSIM. Here's my result with v0.90.7 with Catmull-Rom: http://madshi.net/melon907cr.png Looks pretty much the same as your v0.90.4 image to me. Your v0.90.7 image looks almost like nearest neighbor downscaled to me, or something like that. I've really no idea what's going on here. As I said, I cannot reproduce any of the problem you're seeing. I've also tried all 3 GPU manufacturers (Intel, NVidia, AMD), just to make sure. Works everywhere just fine for me. You can please create a debug log for me with v0.90.7 with Catmull-Rom LL? Can anybody else reproduce omarank's results? |

Looks fine here.
I do get an image that looks much like his when I use the two GPU texture scalers, ie. NN or Bilinear, but any of the pixel shader look fine.

Debug log after a reset of the settings: http://www.mediafire.com/download/kk...fter_Reset.rar Debug log with my settings: http://www.mediafire.com/download/rm...y_Settings.rar I get the same result in both the cases. I hope you have seen the screenshot which I shared in my previous post showing the reddish image that I got with SSIM Clean AR LL downscaling. |

GPU driver version: 10.18.10.3304 OS: Windows 8.1 64 bit It’s an Optimus Laptop. I disabled the nvidia GPU for some testing. I can maybe test with that too later. I have an AMD system as well but I will be able to do testing on that system perhaps day after tomorrow. Quote:

madVR v0.90.8 released
http://madshi.net/madVR.zip Code:
* fixed: downscaling "a lot" on some GPUs/drivers produced nearest neighbor * fixed: NNEDI3 doubling + SSIM downscaling could result in green tint |

You might have a point but the problem is that both SR's with a strength of 1 are already very sharp so in combination with NNEDI3 it's all very seriously sharp and "clean" SSIM makes it even sharper, I'm in the market for a sharper CR AR LL and SSIM in .4 was just that. Anyway, I'll play around with bicubic downscaling as it comes with a whopping number of six sharpness levels

For those interested, here's another comparison, downscaling soccer *a lot*, to simulate "pip" (picture in picture) use:
From what I can see "SSIM detailed" reproduces the texture of the soccer field with the best detail, but the white circle in the middle is terribly aliased. Would be nice if we could combine the best of SSIM "detailed" and "clean" into one algorithm, I guess. In that case simply use Bicubic AR LL. Catmull-Rom is identical to Bicubic50. So if you just want something a little bit sharper, try Bicubic75 AR LL, or maybe Bicubic100 AR LL. |

This question was not answered yesterday and buried in subsequent posts:
Can someone tell me the purpose of the option to turn off 3D in the operating system?

When looking at the detailed image, it's not just the circle that looks quite nasty, but also the score banner and it's fonts that actually look blocky now, and the playtime clock (look at the 3, which is almost complete destroyed) is barely readable anymore, which is already going into the opposite direction of what we're trying to achieve. Also the banner background color gradient suddenly looks wrong compared to Catmull or Lanczos. At most, I would let clean be like it is, while you could try and tune "detailed" to maybe be even better than clean. Remember though that what we're seeing with detailed is a heavily modified image in some parts, which is what I would keep away from at all cost. EDIT: When comparing this on a high DPI display like an iPad 3 (sRGB at about 2.2-2.3 gamma) the playtime clock is becoming perfectly readable with clean (great improvement to Lanczos, Catmull and Bicubic), while on the detailed image I am not able to discern the 3 anymore, it looks like "]". With clean, the whole image gets a nice increase of sharpness, and readability and visibility of fine detail is improved, but not to the point of being obtrusive, like the detailed one is.
