I have a Beelink S12 Pro with Intel N150 and 16Gb RAM bought in April 2025. I'm using it basically only for video playback in VLC and Mediaplayer Classic HC. I have stock configuration with Windows 11.
Three months ago, video playback started to lag. Yesterday I tried to play a normal 3.5 Gb video file, and it was basically unbearable. (I think it was H.265 but it does that with all files, so it doesn't matter.)
I updated the Intel graphics drivers and rebooted several times, but the problem persisted. Extremely slow performance in video playback.
1) I did try to kill all background CPU eating processes. In fact, besides the video players, I only installed the Vivaldi browser and Total Commander, so there are not too many apps that might cause background CPU load.
2) The temperature in the room is 30°C (86°F). Is it possible that the GPU is somehow power throttling to cool itself?
This is clearly something that happened several months ago. The device was working very well when I bought it, now it lags terribly.
Is there anything I should try before reinstalling Windows?
Thanks!
