That 650 Ti should still be great for MadVR but the 660 Ti is much faster. Last edited by Asmodian; 26th October 2012 at 02:09. |

@6233638:
Thank you! Again, this shows that Catmull-Rom + AR downsampling (through linear light: it has to) is really high quality. If it was not, it would be obvious. As it turns out, except for the better anti-aliasing of EWA QuadraticJinc, and the slightly better anti-haloing of Catmull-Rom AR, the two methods, amazingly, are quite close. Catmull-Rom + AR is also slightly sharper. (Note: EWA QuadraticJinc is the "natural" downsampler of my arsenal. It's not as sharp as EWA LanczosSharp or EWA Lanczos Radius 3, which is almost as sharp as tensor Lanczos 3 (which is too sharp IMHO anyway, although lots of people like sharpness). It also has less halo.) P.S. Moire drives DSLR folk nuts. So, I paid a lot of attention to it. P.S.2 If you enlarge both, you can see the usual difference between a high quality tensor method and a high quality EWA method: The checkerboard mode is suppressed with EWA, and not with Catmull-Rom AR. Same with the fly. Last edited by NicolasRobidoux; 25th October 2012 at 22:14. |

I'm also quite impressed at how EWA quadratic B-spline windowed Jinc 3 (which is a linear method) manages to compete with a nonlinear method with explicit halo suppression without being much softer.

I've got the GTX 660 installed with 306.97 drivers and it is working fine but I want to check if I've got the correct settings esp colour space:
Setup: HTPC --> HDMI --> AVR --> HDMI --> TV/PJ (note: the TV was prof calibrated a few years ago against the Cable Box that is on the same HDMI Input to the TV from the AVR so I'm guessing it is Limited Range) Current Colour Space on the Dedicated HTPC (eg no desktop or game useage): Limited Range in Nvidia and Full Range in madVR - When using the AVSHD 709 test patters for Black, APL and White Clipping I see flashing just above 16 (Reference Black) and just below 235 (Reference White) which I think is "Correct". I also tried using the madNvLevelsTweaker to push full range in the driver and while this worked I did not notice a change in the test pattern behaviour. When I change madVR to limited range then I see all levels of the AVSHD 709 test pattern flash regardless of if the driver is in full or limited range mode (note: I've not tested with the PJ yet that is on the second output from the AVR). My real world test BD for this is the Spinning Cube on the opening scene in Transformers as there is alot of detail on the surface of the cube that can get hidden in the "shadows" as it spins and I the extra detail is certainly noticable when madVR is at Limited. - Any suggestions on the Colour Space in this setup? - Any other tweaks in the nvidia control panel that should also be changed from default. Thanks! |

madshi,
I have come across a problem with Zoom Player when using MadVR. Playback won't start on the first try when using the delay playback start until renderer queue is full option and Zoom Players automatic subtitle stream selection. It will start normally if you press play a second time or don't use the above option. Subtitle Settings. http://www.mediafire.com/view/?zww21g5ua3ebe1f This only happens with video files that use PGS (Blu-ray) subtitles. Test Video. http://www.mediafire.com/?7ge5zvk6k99g22y Zoom Player 8.5 Max MadVR 0.84.3 LAV Splitter / Video (CUVID) / Audio 0.52 xy-VSFilter 3.0.0.65 GeForce GTX 580 (306.97) Windows 7 Pro Thanks.

Several reviews claim that the 660Ti doesn't make much sense over the vanilla 660 due to the price difference, and as far as "Floating-point performance" is concerned the GS 650Ti reaches 1545 GFlops, the retail 660 1881 GFlops and the 660Ti 2459 Gflops. Using CUVID, my 264 GFlops() 8800GS can do full Jinc3 AR 25fps SD to 1080p(60% GPU load) and native 1080p Jinc3 AR chroma(77% GPU load), I'm hoping to be able to process 59.94fps SD, 29.97 1440x1080(with a 16/9 DAR) and 25fps/50fps 720p Street prices with shipping go as follow around here: 650Ti: 130€ GS 650Ti: 140€ 660: 205€ 660Ti: 270€ Quote:
They also posted close-up pictures of many LCD panels. Apparently, all you need is a digital camera with a macro mode...I might try that on a rainy sunday. Last edited by leeperry; 27th October 2012 at 02:14. |

PS: even checking "disable GPU gamma ramps" doesn't bypass the graphic card's CLUT on my system. Last edited by leeperry; 26th October 2012 at 16:49. |

So Windows 8 is officially out now today. Is anyone else experiencing issues with madVR's refresh rate changer?
1080p24 is outputting 1080p23, and 1080p60 is outputting 1080p59. I am able to select and use 1080p24/60 on the desktop without any problems outside of madVR. |

If I load Cyberlink on the HTPCs they still won't play DVDs with madVR. I've tried latest lav decoders 0.52 still no good. This is doing my head in I've triad the GPL Mpeg2 decoder - no better. I really wish we could get to the bottom of this!

In the madvr wiki i found this:
For NVidia GPU owners I recommend to create custom resolutions. That makes sure that the GPU output is untouched. With the default HD/SD output modes, the GPU driver stretches the data behind madVR's back which can result in banding problems. I just added a 50hz resolution from the list. is this not enough? can banding problems still occur? what excactly is my gpu doing? I also found this: For NVidia custom resolutions and ATI PowerStrip tweaking, here are the official CEA timings you should use for the various 1080p formats: Code: Refresh Rate, Horizontal Active Pixels, Front Porch, Sync Width, Back Porch, Total Pixels, Vertical Active Pixels, Front Porch, Sync Width, Back Porch, Total Pixels, Pixel Clock 23.976Hz, 1920, 638, 44, 148, 2750, 1080, 4, 5, 36, 1125, 74.2500 / 1.001 (= 74.175824175824175824175824175824) 24.000Hz, 1920, 638, 44, 148, 2750, 1080, 4, 5, 36, 1125, 74.2500 25.000Hz, 1920, 528, 44, 148, 2640, 1080, 4, 5, 36, 1125, 74.2500 50.000Hz, 1920, 528, 44, 148, 2640, 1080, 4, 5, 36, 1125, 148.5000 59.940Hz, 1920, 88, 44, 148, 2200, 1080, 4, 5, 36, 1125, 148.5000 / 1.001 (= 148.35164835164835164835164835165) 60.000Hz, 1920, 88, 44, 148, 2200, 1080, 4, 5, 36, 1125, 148.5000 I cant seem to change all theese values in the nvidia driver. The ones that i can change are set as above by default - maybe except for the 23.976 profile. Is it correct that i dont have much use for all of this this when i use reclock and a 50hz setting? (using 50hz lets me whatch ether pal content or 24hz content without having to change settings + it seems more stable for some reason + films are a tad smother without having the so-called soap opera effect.) |

Also, maybe someone else already reported it but whatever page I close mVR's config on, each time I close it, the next time it will reopen on the main page of my active display under /devices/...it was pretty handy for rolling purposes when it was remembering the last active page

Because OLEDs have no backlight, everytime they show black they shut off the pixels, there isnt really another way for them =P

Well that doesn't make sense. If the pixel is shut off then that's surely as dark as possible, unless there's bleed from the other pixels or something. I can't see how a screen with a backlight could ever be darker than an OLED. From what I've seen OLED can be brighter too.

I don't know the technical reasons behind it, but they are definitely not turning the pixels off in their head-mounted displays, and a number of OLED displays are incapable of turning the pixels completely off.
The specs Samsung announced for its 55" OLED panel were only 150,000:1 at a brightness of 600cd/m2, which is roughly on par with the Pioneer KRP Plasmas. (once both are calibrated to 100cd/m2 brightness) Last edited by 6233638; 26th October 2012 at 20:19. |

It would depend on how the video was encoded I imagine. It could be encoded as RGB or monochrome video.
