Jerky Full Screen Preview

Photostory Deluxe Version 20.01.62

My old PC really struggled with full screen preview of a photostory deluxe project and even at 1/2 resolution was unbearable to watch. So I upgraded to a new pc with B560M AORUS PRO AX (U3E1) Motherboard, 32gb RAM, 11th Gen Intel Core i7-11700 @ 2.50GHz CPU, GeForce GTX 1660 SUPER Graphics Card. Imagine my dissapointed the first time I used Magix and ran a project preview at full screen. The playback was more jerky than with my old tired and low spec PC. Well I played with Magix display settings to no avail, even at 1/2 resolution playback stuttered, stalled and jerked about and was almost unusable (My very old PC was quite reasonable at 1/2 res)

I made sure all windows updates, software, firmware, drivers etc were up to date but still the problem was there. By luck I came across Windows Graphics settings and found Windows GPU Hardware Acceleration was turned off. Turning this on fixed the problem almost 100% although there are some zoom/pan images it still jerks a bit with but its quite acceptable now. I went back to Magix display settings to try and further improve the slight stutter but I have had to resort to Compatibility Mode.

At least its very usable now but PLEASE if anyone has any further advice on the subject I would be very gratefull

I have attached screen shots of the settings I found seems to best suit my PC

Kind Regards David

These are the settings that work best for me:

If you are not gaming on the computer then also replace the Nvidia gaming drivers with the Studio version available here.

Hi John. As it happens I did install the most recent Studio driver but it had no effect, I will try the let Windows decide for Magix option on my old PC I think it made a slight improvement so its worth a try. Why do you have Windows Hardware GPU Acceleration turned off?

Hi John, tried the Windows Graphics app setting and it had a similar effect to enabling GPU Hardware Acceleration, now it makes no difference if GPU Hardware Acceleration is turned on or off. In the Project I'm using to test these effects one slide still stops and jerks and its always in the same position no matter what Graphics settings I change, must be something about the pan/zoom of that particular slide. However the rest of the Project previews perfectly so setting the Windows Graphics app for Photostory seems to be the key to my problems. Thanks for that Regards David

@David-Robinson5527

Are you working with 4K video?

Some effects and objects like Titles are not hardware accelerated and rely on the CPU for rendering for preview or export. With 4K video this puts a strain on the CPU which often cannot keep up with some of the effects.

Are you using the Half resolution option in the Preview monitor settings - see image below

This reduces the preview resolution and reduces the load on the CPU.

Hi John

I have been running with 4k video set but unticking that made no difference, however since changing the previous settings suggested by you previewing at 1/2 resolution has stopped the stutter on that one pesky slide/image. It made no difference before changing Windows Graphics to Auto for Magix Photostory. Thanks for your advice.
