Default 387.05% CPU use.

Is this possible?



Sound just crackles and vanishes at this point.

These are the plugs, there are two instances of what you see here, sims running in high quality and in stereo:



So, understandably quite tough on the CPU, but this PC is an i7-2600, surely it should not be crippled by this?

Soundcard is a Focusrite Saffire PRO 24, running @ 192 buffer, and 24 bit, 48.

I'm betting on a 'wonky' VST (that is a technical term ). I would check those plugs, removing them one at a time from the offending group and see if the CPU use drops back down.

Aside from the comic possibilities of the premise, I'm curious about this as well.

maybe it's some math error that confuses single and multiple cores??

Possibly, for example Window's own performance monitor shows 100% per CPU core. IE: 100% would read as 400%. I don't remember seeing this in Reaper's perf meter though.

At 888% there will be a flash. You will wake up in 1712. Look for a guy named Emmett Brown.

I seriously doubt your readout is accurate. Any of those plugs 32bit? When I'm rendering video in 3DS Max or something scary CPU intensive (and Audio isn't even close) and my system - also an i7 - gets close to every core capped, the whole thing slows down to usability. There's not just a crackling audio thing - you can literally see the mouse lag when you move it. All the fans will crank way up and the thing actually sounds like it's straining.

An i7 can actually push past 100%. They are made to overclock on the fly (well, the K versions). You push enough math at them and they will try to compensate.

Its probably a denormal issue.

Try bypassing the plugs one at a time until the problem goes away.

That, or he may need to turn off hyperthreading in his BIOS.

Here's some nice links about hyperthreading causing problems:
