BOINC/Lunatics + Diablo II on Win7-64

<< < (2/5) > >>

Raistmer:
Did you check what apps were running by BOINC that time?
Are you sure that they were CPU-only apps?  your GPU is capable to work with BOINC too. At least 3 projects can use it (MW, Collatz and SETI@home beta + SETI main with app_info installed).
If GPU-based app running, game expirience definitely will be unacceptable. So such possibility should be ruled out before doing reports to BOINC devs.

I've seen negative effect of running CPU-only BOINC apps (idle priority!) on video playback under Vista on Core2 Duo notebook.
I don't see such effects on single core AthlonXP (much less powerfull CPU and maybe even GPU) under WinXP.
Never tried D2 under Win7, but under WinXP it was never bothered by BOINC.
SO exclusive tag could be the single option indeed...

Yeah, I'm amazed it performs so badly. And, although you didn't ask me, I've made sure that GPU processing is inactive during the playing of Diablo II. I did try that at first, but that made the performance totally unacceptable.

I also have the video-playback problems you mention under Win7 (both with Mediaplayer and VLC) when BOINC is active. It does seem the fact that they run in low priority does not cause them to be swapped out when higher-prio stuff is running. :(

Isn't there some sort of patch available or planned to fix Win7's scheduling in this regard?

Regards,

Patrick.

You can probably thank this guy to some extent:
  http://en.wikipedia.org/wiki/Andrew_S._Tanenbaum

For insisting that in an OS all non core drivers/services/applications should be pulled out of Ring 0 (Kernel Mode)  into user mode.  Being more robust and secure has penalties.  .... Maybe you could *try* playing with Process Lasso & see if some fiddling there helps ( http://www.bitsum.com/prolasso.php )

Pepi:
Jason, can Lasso "manage" problem I sow on AMD comp: if Cool and Quiet is enabled then GPU crunching is slower about 20%

Raistmer:
IMO - no.
C&Q will try to keep you fan at lower speed by throttling CPU freqs.
Disable this technology, it suitable for noise reduction from fan, not for high-performance crunching.
