Vin,
I'll post a quote from that thread;
''Hi all
FWIW I can clarify the following.
I have a Core i7 Xeon 4.2 gig quad-core [ 8 cores in total ] DAW.
I have a simple Sonar 8.X test project.
- 72 Tracks each running 1 x Sonitus Verb 1 x Sonitus Comp and 1 x Vocal Strip - all input monitoring on, all at 32 Samples / 0.7ms latency @ 24/44.1 - Layla 3G ASIO driver - in total, 216 EFX input monitored.
On my DAW the above project has my CPU sitting around %83 but even at these high loads, the CPU spiking - especially with the Sonar 8.5 meters is massive - constant and erratic "amber-ing" and " red-ing " on the cores bouncing all over the place - Windows Task manager reports a similar story.
Turning the Power Mgt to " always on " or " full " or whatever does not change or fix this.
The only thing that does is the reg edit in my first post.
I dont know how hard / high Noel and the team were testing this issue, but the above is my reality and the fix " fixed " it to being perfectly even and flat subject to the * in my first post.
To me, this is a no-brainer tweak with zero downside [ other than it effectively stifles power mngt - but who cares in a dedicated DAW ] and a massive upside ie: all cores all on deck all at the same time all sharing the load evenly regardless of overall CPU load regardless of a small-cpu-load-project or a massive-cpu-load-project.
If you dont want to do the tweak please dont - but other than the power saving caveat above - I cant think of any reason not to do it - there is only upsiade.
Tom''
intersetingly it didn't work work this guy.
