I'm not following youYou said you wanted madshi to add a feature to MANUALLY change the refresh rate and I simply suggested a program that does exactly that not only under MadVR but under everything, of course it does not detect the actual fps of what is going on screen, for that just use the built-in MPCHC autochange fullcreen monitor mode which in my case gives always the correct results even when MadVR fails

Anything I can do? Provide a sample, or let you access my laptop remotely perhaps?

Problems occured:
1.At adjustment the active mark on Jink in image upscaling vanishes. 2.The new screenshot option through madvr does not keep influence of external active filters.

Well, I think cards >= GTX 260, >= GTX 460, >= GTX 560 and >= GTX 660 should all be able to handle these settings, at least for commercially available content. My TV has native resolution of 1360x768, so madVR always has to do either upscaling or downscaling. I have tested these settings on a variety of content and haven't encountered any serious drop in performance while rendering. GTX 260 has VP2 hardware decoder. It gives up on high bitrate (>100 Mbps) H264 videos, some VC1 videos and of course those fancy 1080p 60 fps and 4k videos.

Just like what I have mentioned, the de-ring and de-block processes with per-pixel-adaptive algorithms. It often needs high computation power, but old-day CPUs were not powerful enough. That's why almost no one design the CPU software-based solutions for MPEG2 decoder.
About the noise reduction and image sharpening (like Darbee), I think most people here don't like it unless it does not kill the details. Fortunately the nVidia Pure Video does a good job about these parts, too. To my eyes that I can see nVidia's Pure Video MPEG-2 decoder indeed does better jobs on handling interlaced MPEG2 video of most DVD and HDTV contents. For very high bit-rate MPEG-2 (>= 20Mbps) and most H.264 HDTV contents, however, I agree that IQ difference is not so much between software and Pure Video decoders. Quote:
The frame dropping only happens to interlaced contents regardless of video content's format and resolution (720x480 ~ 1920x1080 4:2:0 30fps). So it looks like the pixel-adaptive deinterlacing algorithm on GTX260+ is very computation power demanding. ps: You can set the card to output 1920x1080 resolution to check this. My TV is 1024x1080 interlaced PDP. But I still need to set it to send out 1920x1080 signal to have best IQ. The Hitachi engineers did different tricks on handling different signal resolution + refreh rates to utilize the panel's best characteristics for this TV.

Ok, if you say older madVR builds might have worked, you could try different older madVR builds to find out which exact version worked and with which exact build it stopped working. Then maybe I can do something. Quote:

hi madshi,
i'm new i have a laptop (with Nvidia GF GT540M) and try to use madVR. When i played the video , madVR always ran on intel graphic card (HD 3000) and sometime it loaded full (100%) then crashed. Please tell me , how to use madVR for Nvidia card ? Thanks. p/s i tried to set high - performace Nvidia processor (Gobal setting) in Nvidia control panel but it's not work win 8 pro x64 |

Right now, for debugging the problem I'm having. Also you could more easily switch back and forth to see the difference (some screens allow non-60Hz input while still displaying at 60).
But for something actually useful - changing the refresh rate takes time and sometimes messes with background programs. When watching random short videos, I'd rather just stick to 60Hz, even in fullscreen. IMO it fits nicely with the other on/off keyboard shortcuts already present.

But as you can imagine the only script that REALLY matters to me at this point is the one that does gamut mapping from AVS, I will embed it within PotP automatic profiles based on frame rate and resolution, save PotP's configuration into an .ini file, make it read-only and roll it when rolling displays = masterplan to success Its colors when using EVR/VMR9 match pretty much exactly ddcc() even though they both use completely different code AFAIK. There are only very slight differences in the <16 and >235 regions so if you don't crush BTB and WTW anymore as you explained earlier, they might very well end up perfectly identical I guess. The other PS scripts that would matter to me would be mirroring (but nobody bothered writing one apparently) and levels conversion.....and that's me that my custom levels/gamut/matrix filename tag feature request will be implemented at some point PS: so, when using the following gamut mapping script: Code:
sampler s0 : register(s0); float4 p0 : register(c0); static float4x4 r2r = { 0.879235699565134,0.10128068131873,0.0194836191161357,0, 0.0448339014270118,0.915215520228331,0.0399505783446596,0, 0.0154998582994896,0.0971141863242463,0.887385955376264,0, 0, 0, 0, 0 }; float4 main(float2 tex : TEXCOORD0) : COLOR { float4 c0 = tex2D(s0, tex); c0 = pow(c0, 1/0.45); c0 = mul(r2r, c0); c0 = saturate(c0); c0 = pow(c0, 0.45); return c0; } 1) untouched: EVR CP: mVR(dithering and all color conversions disabled): = identical 2) aforementioned script processed: EVR CP: mVR(dithering and all color conversions disabled): = not identical Last edited by leeperry; 1st December 2012 at 18:05. |

That leaves two possibilities: a problem with the latest driver, or MadVR deinterlacing has never worked on Arrandale.

I think someone should create a separate thread with easy access to PS scripts in the OP, much like the one they have on HCFR. |

On my GT430, Jinc4 upscaling (576p/720p24 -> 1080p24) renders in around 35-40ms which is too slow really.

It won't "default nearest neighbour", it will just do no image scaling (but still chroma scaling). But even if I take 576p or 720p, there's no noticeable difference in rendering time.
Indeed, your GT430 is not able to handle Jinc (but it's a very low market GPU), the same goes for Intel HD3000. My point was not to tell all GPU can handle Jinc, but no need to get latest expensive GPU to handle current cases (except if you're a perfectionist which adds several filters). |
