Fairly random but frequent huge cpu usage
#1
I am kinda new to this particular setup so I would like to know if the scenario below should be expected behavior or a known issue or that some combination of hw/sw on my end is likely to be the cause. In case of the latter any tips would be appreciated.

System:
- i7-920 6gb
- ati hd 4890 1gb
- display driver 11.9 & 12.1
- win7 x64
- Eden-pvr Beta1 - build 59 - git rev. 007a341 (3 Jan 2012), also tried a few builds from 1-3 weeks earlier
- t! stable (also tried a svn checkout on 13-1)

Symptoms:
- maximum cpu load (1 core completely maxed) while navigating around in the menu's
- gui almost freezes or is very choppy
- input commands barely register
- doesn't always happen, but i can reliably trigger it by moving around in the menu's quite fast
- seems to happen more often with video playing, but also without, during normal use it will always happen within 15 minutes of usage or so
- about half the time it recovers after some time (10-20s) of maximum load, sometimes i seem to be able to 'loosen' it by moving away from the screen where it started (which could be any afaik) resulting in cpu load dropping a few seconds later
- other half of the time cpu load will stay at maximum, or becomes very sensitive (e.g. over 50% core usage at every small gui activity)
- happens right away after boot, nothing else running
- disabling hyperthreading to get twice the power per core doesn't matter, it eats everything
- gpu usage remains well below maximum at all times (2-20% or so, depending on what's playing and how fast i'm navigating)
- confluence skin works like a breeze, no serious cpu or gpu load at any point


edit:
I realized i was completely focused on the pvr branch because i 'need' this.... i installed eden beta 1 now and it seems to perform quite a bit better... i still get the max cpu spikes but they drop down to normal levels much faster, almost to the point where i'd say it's a non-issue but they still take a few seconds, so any feedback would still be appreciated, if only to have something to focus my research on for the pvr branch... Thank you in advance
