The real difference is in memory bandwidth, a GT440 with GDDR5 will have a drastically higher memory bandwidth then a GT430 with DDR3, which can make quite a big difference in some cases.

Actually, is the memory bandwidth of the gpu as important for madvr as it is for gaming?
Since we are talking about HTPC-use, the power draw/dissipation is also important, and in some reviews of the 6400-6500 Radeons I noticed that gddr5 ram added about 10W to the overall power usage of the card (compared to gddr3 model)... For that reason, it could be a good idea to go for ddr3 to get a cooler card (provided it won't cripple madvr too much). |

What is causing low Queue numbers?
Lately, I am having problems running MadVR (with Lav CUVID) in JRiver MC16. I have big time hestitation and freezing playing back BD material. My system is a ASRock H67, i3-2100, nvidia GTS450, Win7 32bit. Everything used to work fine - I don't know what changed to cause this problem.
When the hesitation/stuttering starts; MadVR status screen shows: decoder queue is 1-/1/8 (I have even seen these numbers lower) upload queue is 1-1/8 renderer queue is 1-1/8 present queue is 0-0/4 if I pause movie the queue starts to increase, movie plays okay then queue numbers drop and movie hesitates/freezes. Sometimes the (BD) movies start and run fine, sometimes I ge this problem right after starting Playback, and somtimes it plays a little then the hesitation/stuttering starts. Seems like first queue to drop is the Decoder queue with the other queues dropping immediately thereafter. My other HTPC is running JRiver too with same JRiver settings and MadVR is great so I don't think this is related to MC16 settings. On this HTPC the queue numbers are always 7-8/8 for first three and 3-4/4 for last one. All the movies play/stream from same local Server (hardwired network) so I know the movie rips are not the problem as they play fine on the other system. I swapped video cards this weekend (GT440 to GTS450) but the problem stays with the computer (not with the card). My Network ulitization is 1%, CPU around 5%, GPU-Z shows around 1% load. I ran Windows Performance test and nothing is comong up wrong. What do I need to check/do to figure out the problem? |

here s a graph of my CPU usage with madVR latest version, LAV Video Decoder, W7 x64, MPC-HC x86, ATI HD5450 with latest cat., Core2Quad Q9550 running @stock, 4GB DDR3. Looks a little bit high?
Running a 1080p23,976 HD .m2ts BR rip on a 1080p projector. What is the best recommendation for best PQ? 1. ATI HD5xxx/6xxx series with LAV video software decoding 2. NVIDIA ? with LAV video software decoding or 3. NVIDIA ? with LAV CUVID |

What blu-ray is this? What I can tell you though is that with madVR you won't be able to do frame interpolation smoothly. I kinda had it working with lower settings and I think EVR-CP on Win 7-64 and a q9450 and 5770.

Is there a way to let MPC-HC/madVR start with a few seconds delay when choosing a file? I ask this because I use XBMC; when running XBMC my output of my video card runs at 1080p60 because XBMC is far more smoother with this. But when I m going to play content from within XBMC (I use MPC-HC as external player) my projector has to switch from 60 to 24 and this takes a few seconds. So I can already hear my movie playing while the projector is still busy with making the freq. switch. |
