1080p stuttering (CPU ok) - phunqe - 2008-07-12
Hi,
I've been posting before about the problems with 1080p playback and the fact that the playback stutters as if the computer was too slow.
Today I downloaded the latest build and tried running a movie in windowed mode so that I could see the performance monitor. The movie played as in full screen (with the same stuttering), but I noticed that CPU was working at around 50-60% only.
So it would seem that the CPU power required is there, but something else is affecting the playback.
Any ideas? (running without problems in other players etc etc).

Could be the same thing, maybe not, but.....
If i set my resolution to 1920x1080/24 and play a video with framerate of >24FPS then i get the very problem you describe.
Try testing different resolutions/refresh rates, another thing i'd suggest you try is checking your audio settings (Linux and XBMC) and drivers.

(Note: My screen resolution settings are weird, i choose a resolution of 1920x1080 and a refresh of around 57, then my display reprts 1920x1080/24)

err... oops, i'm using the linux build, never noticed that.
I guess the same things are still worth checking though, if you didn't already.

I tried it now and it's the same unfortunately. I guess I would have had the same problem with other players (such as MediaPortal, but there they play perfectly).

I am also using the latest build in a fresh copy of Windows XP. Plenty of RAM and HDD; however, when increasing the resolution to 720i, movies start playing only sound for around 1 minute, then the video starts and tries to catch up with the sound until synchronization is completed. Weird, I had leave the settings to Best Possible, even though quality is not great, it is still watchable.
I will try to tweak the settings a little more until quality gets better.
