Topic: Performance is too low - but CPU load is just 50% and GPU just 12%

I installed SVP and tried it with an FHD-Movie. I am getting the on screen message "SVP Performance is too low. Try to lower the profile settings (SVP-Index = 0.36x). The sound stops every few seconds. At the same time, CPU-Load is around 50% and GPU-Load is 12 %. What am I doing wrong?

SVP-Mark tests indicate a quite-ok-system. Only thing I wonder about is the low score at "48 fps - vectors search" of 0.82x (39.5 fps).

My System:
core-i5 760, 3.163 GHz, NVidia GeForece GTX-460, 8 GB RAM, Windows 7 64 bit.

Re: Performance is too low - but CPU load is just 50% and GPU just 12%

sounds like splitter / decoder / render issue

show the list of DirectShow filters in use while playing this video

Re: Performance is too low - but CPU load is just 50% and GPU just 12%

I am still struggling with this Problem. It seems to occur only when the Video is displayed on the secondary display, and it disappears in win 8. I am using XBMC Gotham RC1 with dsplayer for playng my videos.

Re: Performance is too low - but CPU load is just 50% and GPU just 12%

May be your screens have different refresh rates and SVP for some reason failed to detect that XBMC is opened on the 2nd one. You can check this condition and specify target refresh rate in "Screen selection" -> "Force..." dialog.
