JFMI, which decoder are you using? Can you try different ones? Quote:

when playing normal progressive videos, my GPU load usually seems to be around 35-50% according to the catalyst activity clock. can only test windowed mode with it though.

Using internal intel decoder I had to manually enable deinterlacing and then it seems give the same result as LAV Video decoder. Every 2 frames are the same. |

I guess we'll have to give this round (GPU load) to EVR but it looses in so many others things that it's not even in the same league. Thunderbolt8, you can use GPU-Z to monitor/record your GPU load even in exclusive mode by enabling and looking at the history graphs.

1080p AVC 30-35mbit: ~35-40 % GPU load 1080i 29.97fps AVC 16,7 mbit: without deinterlacing: 30-46% 1080i 29.97fps AVC 16,7 mbit: with deinterlacing: 45-73% 1080i VC-1, without deinterlacing: for a few seconds 25, 38, 42% load, after that load = 0 (????) 1080i VC-1, with deinterlacing: 0 % load all the time (????) only time of those 5 times, the video played absolutely smoothly was when I played the 16,7mbit 1080i AVC video with deinterlacing deactivated. even in case of the 1080p video, in between smooth playback often stopped for 2 seconds before it went back to smooth again. so I guess the conclusion is my CPU is too slow? -.- I can definately get all normal progressive AVC stuff to play smoothly if needed. but no chance in case of VC-1 up from a certain point, because multithreading is not supported.

CPU load is at 40-50% during playback of the problematic files. Is there a way to find out how many threads are currently active in the MPC-HC process? I'm using LAV splitter/audio/video 0.39. But since the one VC-1 sample which uses the Microsoft splitter/decoder shows the same problem I don't think the decoder is the problem. But I'll also try the MPC-HC internal ones when I get home.

From there you can see CPU use on a per thread basis, what's running under each thread, and thread priorities. |

http://www.avsforum.com/avs-vb/showthread.php?t=1157287 Do you see the same problems with that? If not, can you please upload a sample of your MPEG2 50i sample you've been testing with? Thx. Quote:

Good to know. I'm just wondering why in cremor's log the rendering seems to always take the back seat compared to other things, although I've already increased the render thread's priority. Weird, will have to look for locking problems. |

There is another good sample on that page at the bottom of post #1 that shows clearly the fluidity of 50 FPS in EVR compared to 25 FPS (or whatever is happening) in madVR. It's called "PAL: MPEG2 - 720x576 (4:3) - interlaced - 25.00fps - 8000Kbps". |

It should be powerful enough. One thing worth trying might be to downdate to 10.11 drivers. In the meanwhile I'll try to reproduce the problem somehow.
Edit: But maybe it makes sense to wait a bit before changing driver versions. I've still some ideas on what to try here. |

hi madshi, whatever you did in this mrduckPankov build corrected this bug:

Madshi. I'd like to better understand how madVR makes use of video card memory. I have an 1GB ATI5670. Watching standard 24p movies I see the GPU memory utilization sit about ~65%. The other day I watched a 1080i rip from a Bluray (interlacing was enabled) and it showed usage of ~90%. Not that I think anything is wrong, I just want to understand how memory is used so I can make a more informed decision the next time I purchase a video card. My criteria so far has been to go with 1GB and faster DDR5 memory.

ps: it didn't fix the slow-ZP-freeze-on-seek-after-madvr-frequency-switch one tho ^^;;
