Most likely 540M itself is too slow for 1080p60, at least I haven't encountered any 1080p60 videos that couldn't achieve 60 fps mark min. on my 470gtx.

That was a false alarm, guys The 540M is quite OK for everything except that 1080p60 results in 1 or 2 dropped frames over the course of a 3 minute clip. [ CUVID + EVR is fully OK, no dropped frames ]

The issue was that I was trying out in full screen exclusive mode. After I reverted to full screen windowed mode, things started looking up and I got performance similar to the GT430.

Apparently, FS exclusive performing worse than windowed is an issue reported by many NV owners to madshi

Its not an issue with madVR itself, just with your configuration of the same.

madVR is not a product that can be assumed to be working flawlessly "out of the box".
Sadly, alot of people don't realize this and rather complain. The default configuration seems to be more appropriate for AMD at this time, but it is certainly possible to get flawless playback on NVIDIA.
That said, if windowed mode works flawlessly for you, no reason to use FSE.

Agreed, 1080p/60 works fine on my GT 430 with EVR. Haven't tried it with MadVR though. I think the AnandTech article says it should work up to 30-40 Mbps but I don't know what their configuration was.

I do know that my GTS 250 (VP2 IIRC) cannot handle 1080p/60 though.

wait, but the gt 430 had no problems in full screen exclusive?

[Andy o]

IIRC madshi had to add those tweaks in order to cater to NV drivers or whatever was causing the glitches.

That's what Madshi says now too.
But I remember in the past he said D3D resolved several problems and then recommended D3D (exclusive).

D3D only improves tearing and smoothness or is it doing something else ?

If it works for you, what problems are there to resolve?
Also, if you use Aero, there is no tearing.

[CruNcher]

its mostly about latency but a stable system with Vista/Win 7 (NT 6) these days should have 0 problems anymore in Windowed mode, though for these small latency increase you get a ton of pros with Aero and in Win 8 latency has been further decreased which was absolute necessary due to ultra fast touch responsiveness needed

To Nvidia owners (maybe specifically GT430)...

What are your current settings for....

General Settings
Windowed Mode Settings

I'm having a hard time getting the MadVR not to drop frames.

For noobs like me, I don't see differences between Overlay Mixer and MadVR. I just follow what guys say is the best. I'm not even sure to see a difference between 24Hz and 60 (3:2 pulldown).
A guy like me does not know if it really works...

So I just ask what in theory are other advantages of D3D (except tearing and smoothness).

Also, if you use Aero, there is no tearing.

Does Aero Sync worth D3D from MadVR ?
On my desktop, I often have laggy scroll on browser, until I move a window. So I'm not sure about Aero VSync quality...

I'm using default settings except "present several frames in advance" disabled. Well, I changed luma upscale to spline, but that's personal preference.

Ditto

Here is a sample TS file that contains a mixture of progressive (1080p/25) and interlaced (1080i/25) video. EVR correctly shows the progressive parts (00:00 - 00:16) as 1080p/25 and deinterlaces the interlaced parts (00:17 - 00:44) to 1080p/50. However, MadVR just treats the whole file as progressive and plays it all at 1080p/25, therefore the interlaced parts show combing.

I'm using LAV Splitter and LAV Video Decoder but since it works fine in EVR I'm assuming it's a MadVR bug!

Its not a bug, MadVR just isn't designed for hybrid sources. For now just force deinterlacing or use EVR.

[DragonQ]

Oh OK. All Freeview HD broadcasts in the UK are MBAFF and switch between interlaced and progressive as appropriate, so this would be a useful feature to have!

[mr.duck]

In some future version of madVR with definable hotkey control, it should be possible for example to setup the D key to switch deinterlacing on/off.

Or tell LAV Video to YADIF it should work, without having to force it on in the LAV Video options (since it can read aspect ratio from stream, I guess it could handle mixed progressive/interlaced material OK too).

[DragonQ]

No offence but pressing D to switch mid-video isn't any better than pressing CTRL+ALT+SHIFT+D. If I'm watching something on my TV via an HTPC, I don't want to have to get the keyboard out every time there's an interlaced/progressive switch in the stream. Leaving interlacing on all the time is a better solution but isn't ideal either.

I've tried YADIF via LAV Video before but it has visible problems compared to hardware deinterlacing, unfortunately.

As for GPU-Z: http://gpuz.techpowerup.com/12/04/20/98v.png

Your memory bandwidth is extemely low : about 28.8 GB/s
My VP4 based GTX-570 has over 150 GB/s.
I guess your low bandwidth rather than "only VP4" might have to do with your problem to play 1080p60..

Is there anyone using GTX 680 with madVR and achieving glitch free playback? Just when i get one file playing smoothly, another file on the same settings will get frequent tearing / stutter / drop frames / presentation glitches, especially on 23/24hz mode. When i had the 580 i never had to touch a thing everything just worked
