The option of 'going big' and undervolting/underclocking also leaves room for expansion of madVR's options, without having to switch GPU again because of lack of performance. But it's just a thought |

What are people doing to get MPC-HC and madVR to use the "High-performance NVIDIA processor" in an NVIDIA Optimus computer setup? Is it still just renaming mpc-hc.exe and setting it up manually in the NVIDIA Control Panel?
Also, are there any other specific optimisations that I should know of as I'm getting random stutters here and there since I enabled Optimus? I didn't have any stuttering with manual switching enabled, but I think Optimus is supposed to be more convenient to use. Last edited by namaiki; 26th February 2013 at 14:25. |

IIRC I was able to get MadVR & MPC-HC to use my nVidia card simply using the nVidia Control Panel (no renaming necessary). This is easily checked using GPU-Z anyway.
Regarding the random stuttering, have you checked your Windows power settings? "Optimize video quality" should be enabled at least.

Hi Madshi,
Do you even investigate if it is possible for madVR to present the 10-bit or 16-bit frame buffer to AMD/ATI GPU's HDMI interface, which is sending with 1080p 10-bit color depth signal to TV? Or it has been already supported automatically? I just noticed that Catalyst 13.2 beta6 driver sets the HD7970 HDMI output with 1080p 10-bit depth signal to the Sony KDL-65HX920 TV automatically. Although the TV's super-resolution engine still does quite a good job, I think it should show some additional advantages on scaled Chroma pixels or 10-bit content's contiuous color shades. |

So I just changed all my flush settings in the Exclusive mode settings to "Don't Flush" and my rendering times dropped dramatically. I had been seeing rendering times of 20-40ms on average depending on scaling and if Smooth Motion was on, now I'm sub 1ms. (it hovers around 0.05-0.10ms) I also have "Use a seperate device for presentation" set to enabled. Hopefully there is no negative to doing this and everything will remain smooth as can be. I run Bicubic75 with AR enabled for Chroma/Image Upscaling and Catmull-Rom with AR + LL enabled for Image Downscaling on my 1080p plasma which only has 60hz refresh rate mode.

With this enabled I'm getting lots of presentation glitches with complex video. |

Hello there. I've got a problem with madvr-after changing video card from gtx260 to gtx660 i cant playback movies using madvr (evr works just fine)-i got like 3 frames per second,rest is dropped.
http://i52.tinypic.com/34ri2i0.jpg -there are only a few dropped frames on the screenshot but its because i ctrl+r'd just before taking it-was like 600+ dropped before. Im using a custom resolution forced in nvidia control panel-72hz with some custom reduced blanking. also,card seems to be pretty unstable when it comes to refresh rate-when i managed to play 8bit video without problems (i cant do it now for some reason) refresh rate was around 70-72,thats a huge difference. (i think it shows lies-it once shown over 77hz- my screen would black out after 76.6hz or so. most of the time,the video remains black,i cant even launch the osd debug screen,but sound is intact,sometimes pausing and unpausing fixes it for 8bit videos and they are watchable,but 10bit videos drop like hell. my filter chain is lav-xyvsfilter-madvr,im also using reclock and haali splitter for mkv files.

The problem is that your display refresh rate could not be measured. I suggest to do a clean install of the driver, and carefully attempt your custom resolution again, its very well possible that the custom resolution is not working properly causing issues in the driver.

is the problem caused because i didnt reinstall nvidia drivers? it shouldnt matter as there is one driver for all the cards,and driver reports the card correctly,as gtx660. Last edited by konakona; 26th February 2013 at 21:16. |
