For what it's worth, on my Intel i7-5960X system it's almost pinned at 29.97 with GPU off. But not quite:

With GPU on (AMD HD6970) the playback is about the same.

Full system specs in my profile.

On both of my systems if you look at fps, its also almost pinned at 29.97 but it micro stutters few times/second. So someone with 1950x or skylake x please test it. Im trying to stay away from video proxys, they take time to make. Thank you

I dont have a Threadripper or SkylakeX... What I have Is a 1800X with a Firepro V7900 card I will try your video file once I get home if extra threads helps

Edit: Well Nicks video plays smoother than mine, mine is between 27-29.97 and sometimes drops to 25 so nop, the 1800X isn't good enough for what you are looking for sorry

Thank you , still looking for someone to test the footage, thanks again!

does a skylakeX have graphical core? If not, forget about intel Qsv HW acceleration, or am I wrong?

I also do not see threadripper having intel's qsv as it is obviously not intel :)

As I understand it, Intel Skylake X CPUs don't have integrated graphics at all. If you're looking for the fastest desktop Intel CPU with integrated graphics, it currently seems to be the Kaby Lake 4-core, overclockable i7-7700K with HD Graphics 630. I would like to see how that plays this footage with Intel graphics enabled for preview. Despite the fewer cores, it might be a better all-round choice because Intel/QSV appears to be well supported for both preview and rendering in VP15, unlike (yet) discrete AMD or NVIDIA GPUs.

Edit: And if that's true, then the best GPU for VP15 build 177 could be whatever is sufficient to drive your displays, because in Vegas you won't be using it for anything else. (Disclaimer: This is speculation until we have more real-world reports, particularly about preview performance with Intel graphics).

Hi Nick, not sure I follow you completely...

Are you saying basically that at the moment the only "preview" assistance is via Intel QS in cpu when modern cards are installed?

I'm using a Nvidia gtx 1080, is it being used for preview as well as render assistance? If it's only being used for render assistance then can I also use the QS in my i7 4790k for preview assistance as well as render assistance?

I enabled it (QS) in the bios but Nvenc is still only showing up as available in VP15. It (QS) doesn't show in Win10 device manager either.

No. You can also do it with an AMD or Nvidia GPU. I was suggesting that Intel graphics currently appear to be relatively well supported for both preview and render, so if you get the "best" chip that has integrated graphics, maybe you can successfully use it for both and not bother trying to accelerate either preview or rendering with a discrete card. Neither AMD not Nvidia is yet well-supported for both preview and render. AMD is good at preview. Nvidia is good at render.

I'm using a Nvidia gtx 1080, is it being used for preview as well as render assistance?

Yes, if you've set that in your video preferences, but I understand it's still not working well.

...can I also use the QS in my i7 4790k for preview assistance as well as render assistance?

Yes. Apparently it has Intel HD Graphics 4600 which are not the latest but the specs don't look that far down. Please share your results if you do.

Ok Nick, thanks. I'll do a search on inet see if I can come up with getting the QS to show, if I do have success be glad to share.

I misunderstood that you meant "but still only Nvenc is showing up" so I've deleted the last part of my reply.

I don't know what QSV isn't showing up. Try updating your Intel chipset driver, preferably an approved one from your motherboard or computer manufacturer, otherwise from Intel.

Ok Nick, thanks. I'll do a search on inet see if I can come up with getting the QS to show, if I do have success be glad to share.

@JN_ I have the same processor, and QSV appears and can be selected in V15.

Did you install Vegas 15 before or after you enabled QS in BIOS?

Maybe it needs to be enabled in BIOS before installing Vegas 15 (so the HW is identified properly during installation)? Maybe re-install Vegas 15 with QS enabled.

Happy happy days. Thanks Nick and bitman.

Really weird, I went back into the bios, enabled QSV again as before, and this time it was just there in Device manager. The best part was I didn't have to do anything else, it was just there in Magix!

Did a quick test using same as before, Red Car, I chose the highest quality QSV setting for my system=7.

This is maybe equivalent to the Nvenc setting of .. Preset = Low Latency - default and RC = Low Latency, CBR HQ.

File sizes are about the same. I've uploaded this extra file to dropbox with the others, i'll update link shortly.

Times ... Nvenc 30s QSV 55s

I'll check out tripleflip 18's file shortly.

Hi Tripleflip 18, I know my system isn't similar, but playback is butter smooth, using the QSV and the GTX 1080. CPU is i7 4790K, 16 GB ram DDR3.

These are my updated test results ...

Higher number is better quality for QSV, but not necessarily for Nvenc, I don't yet know the
correct quality "best" order.

Hi Tripleflip 18, I know my system isn't similar, but playback is butter smooth, using the QSV and the GTX 1080. CPU is i7 4790K, 16 GB ram DDR3.

Thanks for looking into it, what are your cpu clocks?

It normally is supposed to run at 4.0, I did the "easy" o/c in bios that adds 15% to cpu and something else to memory, I don't think it makes hardly any difference because the nvenc is definitely a seperate asic. Definitely playback of your clip is aok.

Maybe a very interesting processor will be the upcoming 8700K, where some expect QSV and that with 6cores. Here we have to wait some weeks.

What is also possible but a little bit tricky is to combine an AMD R9 390X in a 5960X system together with a nvidia (in my case a Quadro K4200 for s3D), what I have at the moment here. Vegas allows such a combination now (with Vegas 13 the system did not start if one had enabled GPU acceleration for the R9 390X and no monitor was connented with this GPU, but that works now in both Vegas 14 and 15).

So basically Wolfgang S you're saying that its possible to mix AMD and Nvidia cards in one system, for v14 and v15? And do the graphics drivers coexist ok without too many issues?

With the promised upcoming improvements for AMD in Vegas it would be nice to have the option to mix n match, if stable.

It would be good if Magix would clarify a little more on these issues, either in the manual or elsewhere.

i don't get it, i just overclocked my 5820k to 4.7ghz and its still dropping frames...................... thanks everyone for testing, JN is there anyway you can turn off the QSV and see real time playback...... thanks

This is a while ago, and the cards are old, but I had my HD 6970 and GTX 580 together in my machine for a few months. I could mix and match settings in VP12/13 no problem. I was probably on Windows 8.1 at the time. Power, space and heat are probably bigger issues than the co-existence of drivers.

@Former user we have almost the same system: CPU is i7 4790K, 16 GB ram DDR3, GTX Titan-X (maxwell, a generation older than your pascal), my question on your test results, how did you set your gpu acceleration preferences in the video tab? Did you match your rendering template (e.g. set preference to nvidea corporation when doing the magix rendering for nvec, and change the preferences to Intel when rendering via the magix intel template?

The reason for asking this I get (weirdly enough) the fastest results setting the preference to nvidea, but rendering out in intel QSV (all default). I just compared speed on default settings of the magix templates for nvec and qsv, so quality I did not compare. Below the result of another source render (I just copied the below stuff from another post I replied)

http://www.dkamera.de/media/testberichte/sony/cyber-shot-dsc-rx10-iii/6_beispielaufnahmen/video/video02.MP4

From this site : http://www.dkamera.de/testbericht/sony-cyber-shot-dsc-rx10-iii/beispielaufnahmen.html

Here are the results from the Belgian jury 🍺 GTX Titan-x (maxwell) and i7 4790k, 16G RAM

Tests A: Nvidea (GTX TITAN-X) selected in preferences video tab

4K Magix NVENC AVC takes 35s 

4K Magix INTEL QSV takes 30s

4K Magix AVC CPU Only takes 2:38

UHDp30 HEVC 30-40mbps takes 4:39

Tests B: INTEL (4600) selected in preferences video tab

4K Magix NVENC AVC takes 1:01  

4K Magix INTEL QSV takes 57s

4K Magix AVC CPU Only takes 2:37

UHDp30 HEVC 30-40mbps takes 4:43

And the winning combination (on my setup) is strangely enough: selecting nvidea HW acceleration, but rendering in INTEL QSV

Renderings were repeated max 3x to check abnormal runtime deviations.

Note that I put dynamic ram preview at default 200, normally I put it to zero for stability or to avoid weird artifacts, putting it to zero will increase nvec render time from 35s to 41s on this trial

i don't get it, i just overclocked my 5820k to 4.7ghz and its still dropping frames...................... thanks everyone for testing, JN is there anyway you can turn off the QSV and see real time playback...... thanks

I just did that, plays smooth as butter, cpu only.

Ive updated also the red car test results with a cpu render only, no HW acc. assist. I also did a cpu only render with QSV HW Acceleration assist, the latter similar to cpu only with nvenc HW Acceleration assist and cpu only.
