Hi there to everyone.

I was wondering if someone could assist me with a problem I am having.

I upgraded to Windows 11 from Windows 10 yesterday and today was my first time trying to encode and produce a video. When I start producing my video and encoding, everything runs fine and the timer to produce a 9 hour video is around 2 hours using hardware encoding.

However, when I tab away from Powerdirector to do some other stuff, for example, just going to Firefox to do some browsing, my encoding time is jumping way high, up to 6 hours.

I decided to look at the task manager to see what was happening. So when Powerdirector is in focus, my GPU is being used 68% Video Encode as well as 35% Video Decode. However, as soon as I tab away from Powerdirector, these stats drop down to 48% Video Encode and 26% Video Decode. There is no reason for this loss in performance and I have never had a problem like this when running on Windows 10.

I am unsure if this is some sort of optimisation that Windows 11 does.

Does anyone have any experience with this? I usually do other stuff while a video is encoding and I don't want to be forced to watch Powerdirector for 2 hours just so I can have my video encoded quicker.

Any help would be appreciated.

Hi,

Please refer to this guideline post here:
https://forum.cyberlink.com/forum/posts/list/85748.page

particularly the item on providing a DxDiag here:
https://forum.cyberlink.com/forum/posts/list/85748.page#post_box_354916

Just running a quick 5hr mockup production, with a lot of color corrections etc, @ a standard 1920x1080 30fps profile with no SVRT, I couldn't get my native Win 11 system to show much difference in usage, other than when playing video files - when there was a slight effect.

I think the DxDiag and more specific details of the production profile and the source material and edits would be useful to allow members a better chance to help out.
