iSeries, you can try that to have automatic refresh rate changes : AutoFrequency

I've read in NVidia forums that their two next drivers release should improve on this, so let's just hope that it really happens. |

Well I confirmed that on a very busy 1080p music video I have, with avisynth scripts almost maxing out my machine converting from 24 to 50fps, and overall finding this video particular difficult, I consistently get about half as many frame drops when I set my Nvidia GTX 295 to "Prefer maximimum performance" as opposed to "Adaptive" for mpc-hc.exe.
Repeated tests shows about 33 frame drops, maybe 1 frame delay over the 3 minute clip with "Prefer maximum performance" and between 55 and 85 drops with 5-10 frame delays whens et to "Adaptive". I'm surprised myself actually.... I'm unsure if its dpc spikes caused by the gpu changing mode or what, but I think I'll be definitely leaving nvidia control panel set to prefer maximum performance, for mpc-hc.exe... I'm unsure if this only crops up when the machine is under high stress like mine was but definitely a large difference between the two...(as I often have 0 frame drops when in adaptive mode with my machine under less stress with avisynth scripts etc...) yesgrey did you ever set gpu performance settings on a per exe basis like I'm doing, just be interesting to see the differences in results so we can come to some conclusion. I'm using 267.24 drivers. Last edited by mark0077; 8th March 2011 at 20:48. |

My plan is to implement the final exclusive mode rendering path first. And then probably refresh rate changing next. How long it takes will mainly depend on how many bug fixes I have to do in between.

Yes I know it's a very good little software

According to NVidia only its drivers April release should contain the full changes that would improve the DPC latency problems. |

Didn't get it to blink like it used to though, will make a log if it does it again. Here are 2 logs, one with desktop composition disabled, one without. Last edited by JamPS; 9th March 2011 at 06:17. |

Recently my graphic card's been heating up and i've found shutting down the process "poclbm.exe" solves it.
I would even kill the process, then later it would start on it's own and somehow use my gpu(98%). I don't know why this is happening, but process explorer pointed me to madvr folder and so for now i deleted it. NVM: Probably a virus.

poclbm.exe is some tool that uses your GPU calculation power to mine for Bitcoin currency blocks. (The more computing power you put in, the more coins you get). I guess you installed that at some point... :d

I've just built myself up a new PC based on a Core I7 950, with hyperthreading. It's very fast
And I'm still running windowed mode as I run an interlaced res for my CRT, and exclusive mode fails. Anyway, I've had terrible trouble getting madVR to play even remotely smoothly - it's just been a jumpy mess, with dropped and delayed frames jumping 20 or more every few seconds. Turns out it is the "upload frames in render thread" option. With that disabled I get rock solid results - I can play for ages (hours) with no dropped or delayed frames at all. Turn it on and the mess returns. All other performance settings left at default. Is anyone else running a hyperthreaded CPU? Cheers Mark |

I have an ATi 4850, cat 11.2 and W7 x64. In this regard, the old PC (Q6600) was the same. |

Ah ok, well if it was me I suppose I would just go and make sure I had the latest bios for my board, and go through each setting in there making sure is A-OK especially ones to do with high precision timing etc... install latest chipset drivers and audio drivers etc and maybe check dpc latency to see if there are issues. I hope you resolve it!

Well,i started using another avisynth script to interpolate 23.976->60 which uses 30%cpu,so now i don't resize to 1280*720 in ffdshow...
Madvr is doing the resize now(about 80% gpu usage ati 5670)..actually it is downscalling cause most movies are 1080p and my display is 720p.... In the settings page there is not a setting about chroma downscalling (in luma downscalling i've selected spline 4taps)... What is the chroma downscalling method? Also,is it normal to take 15-20 minutes for my fps to stabilze at 60fps (actually 60.02fps as per mpchc statistics)...shouldn't that be exactly 60fps? |
