Multi core support, what is exactly supported?

[Rhopman1986]

Hello all,

I think I asked this before, but perhaps my question was too long and vague back then, so I will try to make it more simple.
Since we now have CPU's which have a lot of cores and threads, (Intel Xeon and i7/i9, and AMD Ryzen / Threadripper) I was wondering what exactly does Corel Video Studio support regarding multi core support? How does this support work? So:

- Is there a maximum amount of cores which are supported with rendering?
- Does hyperthreading also make a difference? or only real cores?

I just cant find any info about this, but for me its quite important to know since I am upgrading my i7 4790k.

Thanks!

Why you upgrade? anything wrong with your i7-4790k setup?

[Rhopman1986]

I wouldnt call it necessarily something 'wrong' with my i7 4790k, but since it is an 5 year old system already, there is a lot of better and more productive hardware out there.
My i7 4790k has 4 cores 8 threads which is ok, but if a 8core /16 threads system like an i9 9900k or Ryzen 2700x will make a difference, I would gladly take it since time is eventually also money. Also I really looking forward having a NVME M2 drive which runs at full speed which is not something that is possible now on my older Haswell hardware.

But my processor choice really depends on how Corel Videostudio handles multi core CPU's and its threads. In example, if it can only use 4 or 6 cores, its not needed for me to get a 8 core /16 thread CPU like the i9 9900k or Ryzen 2700x.


Thats why I really would like to know it, and dont really understand why there is not much info available on this.

As far as VS2018, you will not feel the tornado whisking thru your projects with new 9900 vs your current 4790
and as for VS2019 who knows...

It really is pointless. At this stage Corel are only really interested in providing bullet points, or a colour change, to sell the latest version. There's still the issue of projects rendering with the proxy cache video and it's been months.

I recently built a i9-7900X based machine, for work, with a raided M.2. card. Yep... performance still awful and no better than the 6850k machine at home. you also have to ensure that you change the CPU priority, for corel, to real time otherwise the darn thing stutters when cutting 4k media. It's, basically, a dog that needs some serious work. Ram use? Might as well just stick 8Gb in your machine and stay at that.


You could always also spend your time using the FREE version of Davinci Resolve.

you also have to ensure that you change the CPU priority, for corel, to real time otherwise the darn thing stutters when cutting 4k media.

For anyone wondering how you do this, go to Task Manager and make sure all tabs are visible by clicking 'More details' in the bottom left of the Task Manager Screen. Then go to the Details tab and find vstudio.exe Right click it and you should see in the dropdown menu 'Set priority'. Click that. It's set at Normal by default in the new menu which appears, but Real Time is at the very top of the list.

This seems to be OS version dependant. I tried that with the task manager for win 7, and there's no "more details" option available, nor is there anything remotely like a priority set for vstudio.exe in any of the tabs for that OS.

[RobertOZ]

The Realtime option for VS does not appear to be an option under the Win 7 platform, if you right click vstudio.exe in Processes, you can set priority to high but not Realtime

[Davidk]

I thought so. VS isn't even listed in my processes tab.

*Thanks for the tip guys (I never set it...)
but Yes it does... on my 7 with the right tool

for the last ~20 years I'm using this
https://docs.microsoft.com/en-us/sysint ... s-explorer
and not the OS's one.

**But I don't know how it will affect my work, as most of the time I run only VS and not with gezilyon apps, and on render I get ~90% cpu so what will go "higher" ???

[Davidk]

Handy link, asik. Downloaded it and tried it out. Video studio only presented in the process list when it's loaded, and changing the priority won't stick; change to realtime, and later close/re-open VS, and the priority is again normal.

David, google for few tools to stick it if have to.
I will try "real time" for a bit and see if it will get me any better and hotter steam out of X9.2.

OR.... save this as bat file in your VS folder
start /high vstudio.exe
if you brave
start /realtime vstudio.exe
link your shortcut to it and get this every time

Don't forget to come back and report your finding

[Ken Berry]

FWIW, with Win 10 the change of priority is also one time i.e. when you close VS it reverts to Normal when you reopen it.

No problemo

Hello everyone,

Its been a while since I asked this question, soor for the delay
Well, in case anyone is wondering, I now have a AMD Ryzen 2700x, and while it makes some difference with my 4790k, but not much to be honest.
I am wondering, why is this still not optimized for multicore? I mean, multi core CPU's are out for quite a long time now. is this just too hard to do for Corel? Or not interesting enough because the target audience are (mostly) not professional users?

Since I am creating a lot of videos now, I might switch to Adobe Premiere to be honest if Multi Core support is not getting better at the new version. Also.. I also have a GTX 1080ti, but I dont see differences in rendering times with hardware acceleration enabled/disabled to be honest.. Or am I doing something wrong?
