Sure... that'll help. Thanks, support!
I've had decent luck with shadow files so you may want to give it a try. It works well for timing -- not so much for color correcting/tweaking.
Also, as referenced in that video link above, there is a way to "render preview" and to "produce range". Both of these options are activated by first selecting a range (with the yellow IN/OUT handles) and then selecting the corresponding option on the contexutal menu strip of buttons just above the timeline.
I know, right? So far I've gotten much better info from this thread!

The problem in preview is probably the 120 fps Full HD clips at 66 Mbps. Users in the past use the 30 and 60 fps clips with no problems. Unable to find a 120 or 240 fps 1080p short raw GoPro clip sample to download and test out here.
Thanks, I'm beginning to suspect that maybe what I'm trying to do is just too intense for preview.. which is fine if that's truly the case - I think the ability to render a full quality preview of just a short segment will get me by just fine. It's certyainly ALOT less time consuming than rendering the ENTIRE project everytime I need to check on it.
I'll probably take more of my footage at a lower framerate in the future.. but man 120fps lets me slow action shots down to 20% and looks soo smooth.

Yes their is and I watched the youtube vid. VERY valuable in your case:

Also just to make sure: in Win 10 is your power options/performance set to MAX? It also can't hurt to pop into your Bios and make sure that beast of a CPU  is running at max.
Good luck
Thanks! I'll check that out when I get home later... I couldnt find anything telling me how to do that, but maybe just didnt think of the right search terms.
Power settings are maxed out.

For a "CUT" try this for a far more precise and laggy free experience:
Click/Select the clip on the timeline
Above on the left you will see scissors. Click them and play with this valuable option.
Good luck
Yup thats what I do to get figure out where I want the picture to cut. The problem is then that I'm trying to line up the speedramp and whip cut wit a music track - thats when things start getting bad.
Maybe what I'm doing is just really really intense and I shouldnt be expecting it to work well - but still.
Besidse turning on shadow files, is there any way to "produce" a final version of only a part of a project? So I dont have to wait for the full video to be produced to check on it but maybe just produce 10-15 seconds from the middle?

Why did you turn shadow files off? They help with exactly what you're trying to do.
Also, what resolution do you have the Preview window set for? Lower is faster.
Also, I just read that there's a new nVidia driver that makes games play 50% with threadripper.
I have set the preview all the way down.. and Shadow files are off because I semed to find a lot of talk all over the internet about how they can cause issues (what i'm not exactly sure) and that they really shouldnt be needed unless you have a pretty low-end system. Is that not right?

I'm running PowerDirector 16, hardware acceleration checkbox is ticked on, shadow files are Off.
The project setup is 1080/24fps.
The raw footage is mostly 1080/120fps GoPro footage.
I have a couple of video tracks, a music track, a few titles, a bunch of speed effects (lots of speedramping and whipcuts).
My system is freshly built and loaded with a clean install of Win10
Ryzen ThreadRipper 2950x (16cores @ 3.5ghz base)
GTX 1080 Ti SC2
32GB DDR4 3200
ASUS Zenith Extreme Mobo
Samsung 850 PRO 512GB SSD
Problem:
The preview performance is so laggy and bad, that I cant tell if I'm getting the cuts right and the timing right on the speed ramping to keep up with the music. I end up needing to generate the final product so I can see how it came out, then go back and tweak my project, then produce again. That's super slow!
Am I missing something? I feel like this should be easy work for my system....
I opened a support ticket, but literally they only thing they told me was they recommended setting my project to 30fps instead of 24fps - I havent tried it yet, but seems doubtful to me that it would help, and even if it did help.. REALLY??
Anybody have any ideas?
Appreciate it.
