What is the main thing that effects VS performance?

[jungleexplorer]

I asked the question many years ago and the answer back then was the CPU was the biggest factor. I am wondering if VS is now harnessing more GPU power or is it still just using the cpu?

Your ancient question is still valid as well as the ancient answer.

Thanks for the answer. I just upgraded my system and bought the latest generation AMD Ryzen 5 2600 3.4Ghz. This thing was so new two months ago, there were only two motherboards that were compatible with it at the time. You can see my system specs over on the right. VS still to struggle with 4K video. I can edit it and all, but it has problems in the preview window. The video is jumpy and the audio skips like a bad cell phone connection. Even after shutting down all windows background processes it still has problems. I have 6 cores working at 3.4Ghz. What is going to take to get a smooth workflow in edit mode?

Have you used SmartProxy? That is designed to make standard def copies of your 4K clips. These will play smoothly. So you do your edits, apparently on the standard def stuff, but when satisfied, the edits are applied to the 4K originals which you then render.

Turn on smart proxy? for any HD clips, but especially 4K.

Doesn't matter what sort of HD clips you use, smooth edit performance uses DVD resolution imagery, and that requires smart proxy being on. For a really smart PC (basically: fast clock - around 4Ghz, oodles of RAM and at least 2 cores (so the app can run in one and the OS in the other, much more is probably a waste since VS doesn't seem to use multi cores in working), setting the threshold resolution higher than 720x576 may work; you would need to experiment a bit with different threshold clip resolutions to check it out. If you are one whose render performance suffers from smart proxy, then get the vsp correct with it on, and turn it off before rendering.

Using the separate processor abilities of a video card to supply extra grunt (faster performance) is the idea behind hardware acceleration, but the actual hardware and software ("CUDA") support in PC's for that is scarce in userland, and the end-result has also been heavily critiqued in the forum.

And given the way VS specs have been rising in the past few years as a result of the extra functionality that's been added to the program (eg, in X9 I could edit mp4 clips on a 2.4ghz 8gbRAM dual core laptop without smart proxy, but by x10 that was a fading memory. SP has become a standard setting in my later versions), I don't think it will be much longer before crappy performance on any platform will mandate that Corel finally addresses the performance issue that's been the subject of many posts in the forum if they want the product to survive commercially.

"in X9 I could edit mp4 clips on a 2.4ghz 8gbRAM dual core laptop without smart proxy, but by x10 that was a fading memory"
Why?
you say that in X9 you could trim an HD project smoothly but in X10 for the same procedure and clips you must proxy them? this is a downgrade to X10 not upgrade from X9.

[Davidk]

Well, yes. 2 sides of the same coin.

Thanks for all the great answers. Yes, I do have Smart Proxy turned on.

I just bought VS 2018. It was $24 bucks with a bunch of other extras, so why not? Is it better then VS10 in the respect of harnessing GPU power, or is just the same design as 10 with a few bells and whistles added on?

try changing the corel process to real time. That can improve things a little (Task manager).
