If no, PCIe 3.0 shouldn't really have an influence on madVR.

I'm not sure. My understanding following along with this thread was that AMD cards were affected by PCIe bus bandwidth more so than Nvidia. I built a new HTPC for other reasons, not to get PCIe 3.0, but I thought that it would help a little.

Nicely put, anyway I just ran comparisons on 16:9 1440*1080p30 video content using RS chroma + SR@1 for both chroma & luma and it's matter of picking your poison between CR AR LL + sxbr25(thick and ringy) or NNEDI3(already too sharp to use in combination with luma SR@1) or NEDI(not very detailed but still sharper than Jinc upscaling) or SSIM 1D(2D is too GPU intensive for my HD7850 and so is Jinc downscaling) + NEDI or plain Jinc AR upscaling(with a slight zoom in order to trigger SR+SSIM).

If the ultimate goal is a "set and forget" solution to mVR's config then a sharpness strength for SSIM would be the ideal choice IMO as it surely does a lot of good but as much as extreme details extraction might be great for PIP it can easily look too digital on double SD/1080p downscaled to 1080p.

I guess in such cases it might make most sense to have such a strength option in profiles so you can specify your set & forget sharpness for different kinds of resolutions (+scaling factors?)

what ever the problem ist it is not the PCI 3.0 connector anymore. it's barely used.

right on

Hey madashi, I sometimes get an "exclusive mode failed" error. Sometimes it works sometimes not. I have attached a log file. Maybe you could look into it if you find some time. Thanks!

Wow! SSIM 2D + AR + LL downscaling looks much better than Catmull-Rom + AT + LL downscaling in 720p videos when Luma Doubling + Quadrupling is used! The result is sharper and looks much closer to 1080p content. In fact, with above configuration + other highest quality settings), 720p with madVR looks better than 1080p with VLC Media Player or MPC-HC with LAV & EVR!

More huge thanks to madshi for madVR and Shiandow for SSIM!

BTW, what does madVR stand for? I know "mad" comes from "madshi", but what about VR? Video Renderer? What does "madshi" stand for?

I can't see any difference between using SSIM or Bicubic125 when doubling 720p and downscaling to 1080p.

Of course, for 4k downscaling SSIM rocks. The only 4k stuff I have are the free demos but SSIM makes them look 4k on my 1080p screen.

I think it depends on other settings and the actual content. I haven't checked out Bicubic125, but SSIM did perform better than Catmull-ROM.

I use:
- MPC-HC + latest LAV Filters (DXVA2 Copy-Back Acceleration), - 10bit+ bit-depth on display with 12bit output
- 0-255 range
- 3DLUT
- Reduce Banding Artifacts (top - low, bottom - medium, but depends on content),
- NNEDI3 64n + SuperRes (strength = 3) for Chroma Upscaling
- NNEDI3 32n for both Image Doubling and Image Quadrupling (Luma Only, both set to Always)
- SSIM 2D + AR + LL for Image Downscaling, Jinc + AR for Image Upscaling
- SuperRes (strength = 3) for Image Refinement (Refine the image After every 2x upscaling step)
- Error Difussion Dither (Method 2 + Use Colored Noise + Change Dither for Every Frame)
- Nothing selected/ticked in Trade Quality for Performance

Yes, this time the memleak is gone completely. Big thanks for all your efforts, madshi!

Yes for sure SSIM is sharper than Catmull-Rom (bicubic50). In terms of sharpness it looks identical to me to bicubic125 when doubling 720p and downscaling to 1080p. I could not observe any additional detail over bicubic125 either when doubling 720p and downscaling so I'm sticking to bicubic125 for this.

Consider NNEDI3 64 for image doubling and cut back chroma to 32. This would offer you a more worthwhile use of your resources.

[kalston]

Agreed, I use NNEDI3 32 for Chroma but ONLY because I got power to spare on my 980 ti. I tried comparing NNEDI3 16 vs 32 vs Jinc AR and I can't see a difference when it comes to Chroma upscaling on actual content (SD or HD). Maybe with a special test file I could see it.

I'm using NNEDI3 256 (+Jinc AR for the final touch) for "image upscaling" (720p>1440p usually) and I can just change the Chroma upscaling back to Jinc AR for 30fps+ content (for 24, 25fps I don't even need to bother).

NNEDI3 won't ever work with newer nvidia drivers with CUVID ?

[SpoCk0nd0pe]

Hey Madshi,

I might have discovered a very minor bug in my setup:
For some reason NNEDI Luma quadrupling doesn't work on my 640x480 source (to 1080p) if I set it to 2.4x (or higher). It does work if I set it to always.

Doubling works as intended.

I'm using MPC-HC, an r9 290 with catalyst 15.7.1 on win7 pro x64. Thanks in advance!

640x480 * 2.25 -> 1440x1080. The factor is below 2.4.

Hi guys, i am having a problem that i think is related with madvr.
Sometimes when i am playing a tv show and i skip to the next episode, it just shows a black screen, and even returning from fullscreen i can't play the episode. i have to close mpc and open the episode again. this do not happen when i am not in fullscreen.
Maybe is related to the change in refresh rate, i use the option to change refresh rate in madvr.
madvr version 0.89.19.
When i am not in fullscreen i can skip all episodes in a season without any problem, but in fullscreen it sometimes give me this blackscreen.
Using windows 10.

Why is there NNEDI3 for Chroma Upscaling and Image Doubling/Quadrupling, but not Image Upscaling?

I am also a bit perplexed about the whole Bicubic thing. Are you saying that all the Image Downscaling options (and perhaps others?) are just renamed version of Bicubic? Catmull-Rom = Bicubic50, SSIM = Bicubic125, Jinc/NNEDI3/others = some other Bicubic???

Well, I gotta say, you sound like it's your first time here.
NNEDI3 can only scale 2x, chroma is always 2x and image doubling/quadrupling part I leave to you.
NNEDI3 can double in both directions X or Y, Super-Xbr for example can only double X and Y.

Also, I remembered reading this same question you asked in 'madVR options explained' thread, took me seconds to find it, http://forum.doom9.org/showthread.ph...05#post1710105

Try 90.10. There was a memory leak which was fixed in 90.10. I had similar problems and 90.10 seems to have fixed it.
