Ok, but .... during the playback of a film (If I can sync the audio) this will not be a problem.
I'm wrong?

yes you can do that. every player should be able to sync the audio. is about 87 ms for gaming mode and over 200 ms for non gaming mode. i have the numbers from here: http://www.hdtvtest.co.uk/news/tx55a...1411073944.htm

Folks, recent nVidia drivers 350.12 are giving a boost to madVR NNEDI3 performance. At least on my 970, I see a 5-6ms processing time reduction, which allowed me to increase NNEDI3 neurons from 32 to 64, while keeping everything else the same (1080p->2160p). Give it a try

Also, 64-bit madVR is now out

Very interesting. The increase of PQ is evident?
The reduction of 5-6ms is with madVR 32bit?

Do you know If Jriver is avaliable in 64bit version to use the new madvr 64 bit?

last question: Is your GTX 970 overclocked?

thank you

Anyone tried the 64bit? Is there any gain?

software decoding is fast because lavfilter 64 is a lot faster for HEVC.

I saw the processing time reduction with both 32 and 64-bit versions of madVR. AFAIK, new drivers support OpenCL 1.2 so that could be where the gains are coming from. I doubt we will see PQ gain by just switching to 64-bit.

I don't know about Jriver, but full 64-bit stack is now available thru mpc-hc+lav+madvr. My 970 is running at stock speeds.

^ This. Some Samsung HVEC 4K videos that were playing like a slideshow before are now running butter smooth with the 64-bit stack of mpc-hc+lav+madvr.

No I don't have Cuvid. I have None selected. But going from x32->x64 for lav was enough to make those videos play butter smooth.

CUVID is just a bad version of DXVA copyback (both have the same performence).

and the hybrid decoder can't do 10 bit HEVC and if i wasn't mistaken lavfilter x64 software decoder is not really slower on a good CPU.

With the 64-bit madVR, if you use the 64 bit version of daum potplayer, you can stream 4k youtube videos in vp9 (they are higher bit-rate than the h264 equivalents) or any youtube video and they will benefit from madVR's processing such as error difusion.

As for Vimeo I still don't know of a way to live stream them with madVR

Does a 750ti benefit from the new drivers? I hope Nvidia bring out a new 950/950ti with hdmi2, hdcp2.2, vp9 and hevc decoding.

Pretty sure it will. I saw 5ms lower render time on my GTX 960 as well.
