Your performance seems fine during a match, so I'm not sure that'd be a CPU issue since CPU utilization should be considerably higher during a match than when in the menus and such.
Maybe try LLE DSP? (Config -> Audio tab) I'm honestly not really sure what could be causing the issue...
BTW, those black-bars in your video* - turn on that widescreen hack man for unstretched widescreen goodness.
*i'm one of those crazy people still using a CRT, so running your video in fullscreen resulted in windowboxing (video making protip: you can upload non-widescreen videos such as 1440x1080 and 960x720 and they'll still have 1080p and 720p but won't cause windowboxing on less-wide aspect ratios like on newer laptops with 3:2 ratio displays or the like)
