CPU and memory usage

marcel-vossen wrote on 4/8/2017, 7:10 AM

Hi guys,

I have built a brandnew editing PC with the specs below, Ryzen 1700 CPU etc.

When I start rendering the CPU is never stressed to more than 50%, how is that possible, doesn't the program use every resource it can get? I figure it would be a lot faster in rendering once the CPU is used 100%....

This is even more extreme with WINRAR, it only uses 10% of the CPU unpacking, even if I do it on the fastest SSD drive I have in the system. Somehow I feel that the software doesn't know how to use all resources, is there a trick to install extra drivers or something? Of course I did install all drivers that came with the MB and Graphics card.

Vegas Pro 14 and Ryzen 1800X here:

Mine goes up to 90% when rendering except mine is the Ryzen 1800X, all is working great here with Vegas Pro 13 &14, if you could send me a file or a link, the project you are using and export settings I could do the same test so maybe we can see what is happening with yours, I have the same RX 480 GPU but in my case 2X8GB 3200 CL 14 of RAM, yours is strange really...

Hi Igniz,

Very interesting... My export settings are this:

What is the output format you are rendering at 90% there? I actually think thats the main difference, because I did a test with exporting MOV and this only stresses my CPU for 10-15%....

Hi Marcel,

Because you are missing a box in your export settings

it looks to me that you did not enable "Allow legacy GPU rendering" in Options/Preferences/General

Hi Cornico,

I did a short test, but that setting doesn't change anything actually, it is still around 40% CPU during rendering. Furthermore, I also disabled GPU accerelation in the Video setting because i got strange effects in some transitions , in preview and in the endresult, blue lines like this in the slider effect:

 

I'm not sure if your setting does the same thing, but Magix admitted this is a bug in vegas 14:

Unfortunately this is a known issue with newer GPU cards our development teams are working to resolve in future updates of the application. For the time being, we recommend users do not have GPU acceleration enabled as we found it actually creates more instability in the product. However, if you absolutely must have GPU enabled some users are able to find success in being able to have their GPU cards enabled with the software as long as the card is running an older driver. You may need to roll your driver back a few versions for it to work properly in the software.

GPU acceleration and GPU rendering are not the same things and not the same settings. The setting I gave you was new in, I thought, build 211, because there were to much reported problems with the automatic GPU-on setting.

I was using MainConcept Internet 1080p NTSC output, When I use your PAL output settings I get the same as you, Task Manager shows around 45-50% cpu usage

So I would say this is normal but I'm not sure

====================================================================

Edit: Man you made me turn my 6700K pc on, and decided to do the same test, although the 6700K seems to use more cpu power in reality it takes more time to render the same exact project, I'm using a 4K video 1:40 min long

MainConcept NTSC 1080p 29.97 output settings (CPU only)

i7 6700K

R7 1800X

-------------------

i7 6700K = 4:30 seconds

R7 1800X = 2:20 seconds

--------------------

SonyAVC/MVC 1080 50p PAL

i7 6700K

R7 1800X

i7 6700K = 3:10 seconds

R7 1800X = 2:23 seconds

so yes, more cores definitely helps, if you don't see more than 50% cpu usage I think it's ok

Did u change Max. number of rendering threads  in Preferences => Video.

I am using Core i7-6700 which has max 8 threads and it was showing 16 by default.

Also are u guys getting smooth, stutter free performance during preview using dedicated Graphic card and more CPU cores with Ryzen?

6700K is showing 16 threads by default as well, if you want absolutely no lags in Vegas please don't use their built-in transitions (they are garbage), they don't even support GPU acceleration, use some GPU-Accelerated Plugins instead and you'll be happy with either i7 or R7, but which one is faster?

Well there is not much of a difference between the two during preview, you start seeing a difference when working with multi-tracks though, for example I can run up to 3 4K video tracks in a 1080p project using 6700K while I can run up to 5 4K video tracks using 1800X all Best (Full) preview with no stuttering, they are both fast really but the 1800X keeps more responsive over time while editing, that is the best way I can describe them.

Hey Igniz,

Exactly what i thought! It totally depends on what you are rendering it seems, I did a test with the Mainconcept output you mentioned and also got 96%!

BTW do you know why this Mainconcept MP4 output cannot use 50 frames/s like the Sony AVC output I normally use? I think 25p will make your footage flicker if its moving too fast...

So this is really interesting to know.

About the timeline preview, how much Dynamic RAM preview have you set in the video settings to preview? I have 32 Gb of internal memory, so I have set it to 2048 now, by default it was only 128k or something, very low. I noticed that this setting makes a huge difference when I use multicamera tracks, more memory lets me preview 5 camera tracks (3 x HD and 2 x 4k) all at the same time in a multicamera view.

Turning on the GPU acceleration improves this preview speed but introduces some strange effects in the slider transition like I mentioned. However, when i replace this slider with a similar effect called 'push' (actually I don't even understand what is different about it anyway!) this problem is gone though...

Did you try typing 50 into the frame rate field and unchecking "Allow source to adjust frame rate" check box?

Works for the Internet HD template.
