I've used 5 tracks, there are a few effects on some clips and up to 4 tracks overlaid at one time, when I preview it in "High Preview Resolution" it becomes progressively stuttery, it stops at some points and goes completely out of sync with the music. The project is about 1 minute long.
CPU usage never tops 60% (most of the time its closer to 30-40%), memory usage never tops 30%, disk usage hardly goes above 5%.
I have set PDR.exe to "Real Time" priority in Task Manager.
It is smoother when using integrated graphics than when running using nVidia, but generally the result is the similar. When using the nVidia 970M GPU usage hasn't topped 13%, when it stutters it falls to 0%.
Any ideas on what could be causing this?
Any ideas on PD settings to check or uncheck or just why the laptop isn't using the available resources?

Hi Henk,
I presume, reading the info of your Nvidia card that you use a laptop (970M)? I have the same problems with a 850M GPU laptop.
Since this is a common problem, here's what I do:
Preview in "normal view" instead of higher quality, but smaller windows. Preview NOT in real time (no sound).
When editing, add your music track at the end of your editing exercise, it slows down the system considerably. Particularly when using a lot of FX's, transitions, etc.
On laptops, the Nvidia chooses "integrated graphics" instead of GPU. I don't know why?
Seems impossible here to change to Nvidia... ???
Defragment your disks before editing, and close all programs such as browser, emailprogs, etc.
Give "HIGH" priority to PDR.exe instead of "Real Time" in Task Manager. Be sure you are not disabling the prog by closing the window! Click the right upper X not under!
I have 2 recent laptops running at 3.2 ghz and they don't fit well when several tracks, I believe they are just not fast enough to edit fast and well. The desktop computers with 6700K and a 970 GPU does the job without problems but they run at
4.2 ghz and could be overclocked?
Try what The Shadowman suggests. I will do that also later this week and inform ASAP.
Good luck.
