Fullscreen Video Out / Graphic Card Recommendation

[styro]

Sorry to bother You again....
Now that the project is somehow working, i assembled the PC for doing the presentation on, 2 x HD-Screens for fullscreen 1920x1080 video + screen for administration,
AMD 7 5700x/32GB Ram/win10
I tried the AMD Radeon Pro W7500 as graphic card, but the results were really bad, fullscreen there where lots of glitches and artifacts and the video was jumpy,
Interestingly there were no artifacts playing in a window. Then i tried the radeon RX570 from my other comp, fullscreen is ok, but the videos are not very smooth also...
So it looks as i have to buy a new graphic card, what are the recommendation for using Usine? On the system, there will be 4 videos playing on 2 screens, shouldn't be a problem . Whats the most cpu-friendly video format to optimize the smoothness of the playback?
Is Win11 better for video-work?

Many thanks for some pointers!
all the best

It depends on the wkp.
if you have many OpenGL Shaders, an good card is required, but in other cases a "normal" one can do the trick.
But you also have to take a particular attention on the sound card : the sound card gives the clock of Usine. To have a good "smoothness" try to reduce the sound card buffer size (ie. 128 samples) or set the audio driver to "NO AUDIO"
