Reaktor + Cubase sx3....cpu problem

Ok, thanks to all of you for your answers!
really cool!

Guess reaktor is just a heavy son of a b*tch ;-)

Maybe in the future an upgrade, but at the moment I'll just have to work my way around

thanks everyone

 

About using antivirus: I don't use any. Antivirus is nothing but a huge CPU and resource hog. If you know how to use a computer and don't run outlook express/IE, etc., use your CPU cycles for Reaktor. Not for Norton.

If you are terrified of viruses, get a mac.

 

Or use a less intrusive antivirus. I've found trendMICRO to be the best balanced between good protection and transparency to other processes. YMMV, though...

same probs

i have the same probs and have read through these pages trying some of the techniques mentioned but still have the same problem.

my system is a 3ghz pentium P4 chip with 2gb ram. i know the P4 chips aren't incredible for cubase but its definately NOT the main cause of the problem.

one thing i have noticed is that the reaktor patch (e.g sinebeats) completely glitches out after a while and sometimes uses up to 70% which obviousley pretty much max's out my cubase cpu performance. BUT! process explorer shows cubase as only using 20-40% of my overall CPU performance?

any ideas chaps? thanks. Dan

 

Welcome =)

Cubase supports hyperthreading, while Reaktor doesn't. That's your difference.

You'll see the same with a multicore system (HT's essentially the same idea, but with everything on one core). Reaktor will only utilize one core or thread per instance.

The best solution? Turn HT off.

thanks for the reply. i tried disabling HT and reaktor seems to be much much worse. as a test for everything i am opening a blank cubase doc and using sinebeats in reaktor. with HT disabled sinebeats is at almost 65% cpu. i cant think why else this might be, its making me a little depressed now as i cant afford to shell out money on a new processor for a while. i hate technology. :angry:

 

i am a Mac person, so i can't really help...but...

maybe the problem is the settings for your soundcard? try increasing the buffer in your audio settings. you should not be getting a CPU of 65% on a pc with your specs. when you say 65%, is that the CPU in Reaktor?

maybe you should say what soundcard you are using.

yea i increased the buffer a little the other day, its at 512 samples now. im using an m-audio delta 44 soundcard. got the latest drivers and everything. i meant the cpu performance in reaktor yea. thanks again.

 

i am puzzled... i have ( i would have thought) a much slower MacMini. using the internal soundcard and Logic 6.4.3, Sinebeats runs at maximum 37% (Reaktor CPU in Logic).

what kind of CPU performance do you get when you use Sinebeats with Reaktor as a standalone?

sowari

 

Yeah, you've got something else going on. Sinebeats will use about 11% of one core in Sonar on my machine. Granted, my machine (a 4600x2)'s beefier than yours, but you should see performance comparable to Phil's at the very least, I'd think.

i get about 17% tops when running as standalone, im gonna try a few things this weekend probs. considering creating another boot OS on a separate drive and installing everything to that.

could my power supply have anything to do with it ?

 

I think it's perhaps worth re-stating that Reaktor is an environment for making instruments, not a single, fully-optimised VST instrument in itself.

So, different Reaktor instruments will place different loads on your PC. Saying that "Reaktor is CPU-heavy" is a bit of an over-simplification: for instance, I can get a drum machine, a bass synth, a loop-glitching instrument and some effects out of Reaktor, about 1/3 of an arrangement for a track, for about 12% CPU, just because each instrument is quite simple in itself.

I don't know about anyone else, but my relationship with Reaktor developed from using the big, impressive factory ensembles to making my own, smaller and simpler instruments which work around my own writing style. So I'd say, optimise your PC as much as you can (Here's a list of hints for XP), then gently persist with Reaktor and see where it leads you.

 

thanks Dave
