Also, since you compared to DXVA, of course it'll use more CPU then before. The Splitter creates one thread for every stream (audio, video, subtitle), and the decoders usually just decode on that thread, causing the info you see. Its only because LAV Splitter created the thread that its being blamed for them, but the highest CPU thread is probably video, and the second the audio decoder.

No - present several frames in advance
^ that setting causes it to use the "old" exclusive mode 7% is high? From all i know, that could as well be the audio decoder decoding some complicated HD audio, putting the video at 4%. Without knowing anything about the system, judging how much 4 or 7% actually is, is really not possible either.

Well, I figured the 7% is what you'd get from software decoding. I get around 15% on average 1080p material (8-bit) but my system is quite dated.

I would try to check out the differences between "old" and "new" since I don't know the difference. At first glance I see presentation glitches now and then, about one each five seconds or so.

As a general rule of course, if windowed mode works fine for you, then don't worry, be happy.
Some users need exclusive mode for fluid playback without tearing, if you don't - great!

I was doing some testing upscaling some 1080p content to 4K recently, and none of the available algorithms really did a very good job of it. For some reason, the scaling issues were far more obvious than with DVD. Perhaps because the source material (good Blu-ray encodes) is that much more detailed to begin with. Everything, even Lanczos 8 and SoftCubic 100 was very aliased. (but the aliasing had soft edges) It makes me wonder just how much better even DVDs can get compared to how they are now. (and how they are now, is the best I have ever seen) I would love to see more advanced multi-frame super-resolution processing eventually, but I suspect that's far beyond the scope of madVR. |

In a related note, how about an emulation mode for the old XP option for a “single display mode” which would treat a multi-monitor setup as one large display?
For example, some users use an IBM T221 screen to display movies, which has a resolution of 3840 × 2400 and is connected using four DVI ports - Windows sees these as four separate 1920x1200 monitors. In XP, you could set it to work as a single display so running a fullscreen program would fullscreen it over all four “displays”, while Windows 7 lacks this feature - so fullscreen applications will only appear in a single quadrant.

Can't say I notice much of a difference for 1080p24 playback though. |

I'm upgrading my HTPC to include an nVidia card (GeForce GTX 550 Ti (Fermi) 1GB 192-bit GDDR5 PCI Express 2.0 x16), but the motherboard I wish to use has only a PCIe 1.1 x16 slot.
Will this make any difference in madVR (or LAV CUVID)'s ability to fully utilize the new card? I'm guessing even 1.0 has enough bandwith to render the images fine, as I think the real work is done in the GPU. But, before I get it all built, I thought I'd ask, since it's easier to change the motherboard before I install it thanks. |

The bandwidth should be sufficient.
I have no idea if it works at all, but i guess it does.

Thanks. from my reading...

It seems the cards/slots are backwards compatible between versions, so I'll hopefully get it built tonight or tomorrow and finally get full hardware de-interlacing |

I have two PC's with nvidia GPU but I'm seeing radically diffrent Present Times:
- GTS450 (ddr5): Present time is usually between 0.1 to 0.2ms in both Exclusive and Windowed Mode - GTX550Ti (ddr5): Present time is usually between 0.1 to 0.2ms in Exclusive Mode but blows out to 10 - 30ms (eg 100 times slower) in Windowed Mode so it drops frames. I've tried updating Drivers, Bios etc on the GTX550Ti but I have No Idea why the very high Present Times in Windowed Mode on this unit - any hints? Thanks Nathan Edit: Even my Laptop with a 320M has OK present times..... Last edited by jmone; 23rd September 2011 at 05:30. |

EDIT - Fixed the issue by reapplying the Std Windows 7 Aero Theme (Control Panel --> Personalization). Seems if you have a "Basic" theme then the presentation times go up by x100. With the Aero Theme applied all is fine (no idea how I had a non-aero theme in the first place).
