XBMC Idle & and Intel QST
#1
Hello Everyone,
I have an HTPC machine (H971 from Gigabyte) which works with Intel QST (Fan Control), Somehow, Only when idle in the the XBMC menu (tested all 3 default skins, the same), CPU Usage goes to ~ 10% to 20%, with 60FPS and the fans starts to work on maximum speed...
I have passed thru the many posts on the forum, but didnt found any
answer for this issue...

The HTPC is based on 965 Chipset and its built in graphics chip.
when watching 1080 movies, it seems cpu work "less" hard than idle mode
as fans go back to be silent...

Any comment will be welcomed!

Thanks,
Ebzed.

I was seeing really high cpu usage on one core. It looked like this while I was idle in the XBMC gui:

The solution, which I just found in an old thread, was to turn off Vsync in XBMC. Settings > Appearance > Screen > switch Vertical Blank Sync to "Enabled During Video Playback" and the problem was solved... well cpu usage has dropped to less than 10% now during idle anyways.

I'm not sure exactly what vsync does so I don't know what negative repercussions this will have but everything in the GUI still looks the same to me with it disabled.
