Why do you say that?

I paid more as I got it day 1. As soon as they were in stock on newegg I pulled the trigger. The one bad part of being on the bleeding edge. Hence i can wait a month or two to buy a 680. As for the "doesn't look like it's top of the line" comment I have to highly disagree with you on that one. It's a most impressive looking card. Lower heat profile and less power consumption than the previous cards. AMD's pricing is a joke. They were just this week forced to reduce the price on all their cards. That 7970 is down to 449 USD now. I agree the prices are ridiculously insane, but, then, I look at the price of something like a PS3 when they first came out and think to myself that a top of the line video card will provide more value in the end. Even if I wanted a 680 right now, however, I can't get one. No one's got them in stock and I'll be damned if I'm going to pay a "premium" to get one.

I was under the impression that GK100 was gonna be top dog, but from a quick google can't find more than rumors before GK104 came out. Code names are confusing enough. I didn't mean it from a performance standpoint. I agree it's impressive, and if I gamed a lot I would probably wait for GTX660, but again, HDMI audio me no likey.

[SamuriHL]

Yea, the code names are nuts. The 680 right now beat the pants off the 7970 which is why AMD had to reduce the price. For madVR, the 680 is beyond overkill. I have no problem with that. LOL! (Well, maybe with 4k content it's not overkill...I don't know). But that will be enough for me. PCI3 won't hurt.

(P.S. I know the 7970 vs 680 is really close. I was being sarcastic with the "beat the pants off" comment....I hope no one takes it seriously)

My plan is this year to get a IVB laptop with either a GTX660m or 650m GDDR5 because of Optimus, but keep a 7000 series in the aging Yorkfield HTPC. If I was gaming, I'd go to the NV camp probably, unless AMD severely adjust their 7800 prices.

[SamuriHL]

I want an IVB laptop myself but I don't know if I can afford one this year or not. We'll see. I need a new TV, as well, and since I just poured so much money into rebuilding my HTPC's both plans may have to wait. My dual core VAIO with a 3450 ain't getting any younger. (Although, to be fair, it does work with madVR....barely)

except that nvidia focuses a LOT on things like FXAA, TXAA, and various texture optimizations that have no relevance to madVR. probably why some things are broken with the new drivers.

[cyberbeing]

Possible wishful thinking that along the way, NVIDIA actually fixed the issue which initially prompted madshi to make 'use a separate device for presentation' the default?

I can't even remember what that option was for at this point. Was that for the 'multi-display issue', the 'madVR can't read refresh rate in fullscreen exclusive' issue, or something else entirely?

The 680 is massively overkill for an HTPC and the 520 isn't powerful enough for high quality MadVR (from what I read in late 2011, things may be different now since MadVR keeps improving). It's one of the reasons why I got a GT 430 instead. It was cheap though so if it ever stops coping with any material I throw at it, I can upgrade easily enough.

[nevcairiel]

The 520 isnt even powerful enough for full quality deinterlacing with EVR, so no, its not fast enough.

Rumors say that in June there will be a mid-end GPU of the 600 series.

I asked this question because i have a simple AMD HD5770, and it performs perfectly. I can switch to full-screen on the secondary (my Plasma), bitstream HD audio etc. etc. and keep using my primary for work at the same time. I have never had problems with refreshrates/frequencies/full-screen problems or what not.

Maybe it's because i do decoding on the CPU (a c2q 9650 EE, which is downclocked atm). ?

[nevcairiel]

My system with an NVIDIA card also runs just fine, some people are just unlucky, have odd configurations or don't have the patience to fiddle with the madVR options.
Granted, with NVIDIA you might need to change more options to get playback working properly, but i can always claim that the defaults are just tailored for AMD.

[SamuriHL]

Yea, having 2 HTPC's in the house, one with nVidia and one with AMD, I can say that configuration is pretty different. However, that said, once you configure it, it just works. nVidia driver updates sometimes introduce problems, but, you can always go back to a known stable driver if it's really broken. The same can be said of AMD from time to time. Pick your poison as they both have benefits and drawbacks.

madshi, I have a TS file that MadVR refuses to deinterlace unless I force it on (with CTRL + ALT + SHIFT + D). MediaInfo reckons the file is progressive but it reckons that about a lot of files that are actually interlaced so I don't know whether that's relevant or not. I have "if in doubt, activate deinterlacing" on.

If I name the file "blah [1080i].ts" and use automatic deinterlacing, it's set to "off". If I name the file "blah 50i [1080i].ts" and use automatic deinterlacing, it's set to "on" but no deinterlacing actually happens. :/

Any ideas?

I just posted this in the LAV Filters thread, but thought it would get noticed here more (apologies if that is not the practice in this forum):

Has anyone tried using madVR on mobile NVIDIA GPUs? If so, do you notice a loss in performance compared to a similarly spec-ed desktop GPU?

For example, a GT 540M vs a GT 430 / 440 using the same DDR3 memory with a software configuration using LAV Video Decoder (CUVID) in MPC-HC is the sort of environment that I am looking at.

Have you already compare the key-numbers from GPU-Z for example ?
I think stuff like Pixel-fillrate, Texture fillrate, bus width en bandwidth could give some indication.
Of course gpu-clock, memory-clock and shader-clock matter a lot for MadVR.

For indication, my GTX-570 gives :
Bus width : 320 bit
Bandwidth : 152 GB/s
Memory : DDR5 1900 Mhz
GPU clock : 820 Mhz (732 standard), shaders 1640Mhz (1464 standard)
Has 40 ROPs / 480 Shaders

I have acer 3830TG with nVidia GT 540M. I haven't compared it to the desktops GPU's - since my desktop is much faster.
But I have abouth 13.60 ms rendering time of 1080p video on 1366x768 display - so it's enough for 60 fps video. But I'm not using CUVID - VP4 is too slow for 1080p@60fps.

Actually, VP4 is plenty fast for 60 fps, average framerate should be over 70 on a typical 1080p file.

Might be a memory bottleneck on a mobile system, it'll probably have slower RAM to limit the thermal properties.

[vivan]

Average - maybe, but I have lowest ~50 fps on some files. I'm used to QS perfomance
