Traktor Pro 2.5 CPU overload
Posted on: 27.05.2012 by Mariano Weigold
Hey Guys, i downloaded the new update and after installing it i started Traktor to play around with my S2. Even when i am not doing anything at all, the CPU load is nearly in the red space... Anybody having an idea what to do? I own a Windows Laptop with intel i5(2x2.3-2.53GHz) which shouldnt be the problem...

if you double, quadruple, or even more the beatgrid, you can set very precise cuepoints that are still on some beat, which is nice. then those will stay when you bring the grid back down to where it's supposed to be. it's good if you want to set one cue point while you're working, but if you wanna do it in the middle of a set, you're outa luck as far as I know.

Thank you for getting back to me,

I have 2.61 installed and did so recently as I was suffering with the same glitches on the previous version, I thought going to 2.61 might solve the problem.

I recently upgraded to mountain Lion again believeing this may help. The CPU load is definitely higher with DVS but I haven't got firm figures for this, I will test tomorrow and confirm.

Thanks again for helping out, I'll have a play tomorrow and give you some extra info. Grateful for the help.

Found this thread, I'm experiencing exactly the same problems as the guys on there. Looks like the audio 6 has some serious issues.

Obviously the quickest method is to try another low-latency soundcard although its possible that the higher latency of the onboard sc pushes the system that much less, thus averting drop out issues....

Looking back, I don't believe it has run flawlessly since 2.5 was released. The mac I use is my day to day computer so unfortunately it is not a dedicated machine but I haven't changed anything drastically that I can believe of.

I run my Audio 6 solely through the usb, could buying the power adapter help?

I had a play with Traktor just using my built in computer soundcard and didn't run into any audio probelms at all.

Maybe it's a soundcard problem??

I just re-read your previous comment. You said that you installed 2.61 as you were having issues with the previous version. Can you tell me if you have ever had Traktor running flawlessly on your machine and if so, what version was installed at that time?

One of two things is likely happening.

1. Traktor introduced functionality in the product that your machine is not happy with.
2. You introduced something into your OSX environment that Traktor is not happy with.

So what changed and what stayed the same?

I believe this is just going to be a process of elimination.....

Right I'm back after finally having a chance to play and test,

When Traktor is running and there is no DVS the CPU load is between 20-29 and with DVS 31-40.

The load metre never red lines but after only a few minutes of playing I get bad audio with loud pops and crackles.

I've got a big gig at the end of the month and really need this sorting out before then.

Thanks again for the help so far.

Hello guys, I've got the latest version of TSP2 installed on my early 2011 13inch MBP i5 upgraded to 16gb RAM. The CPU idles around 30% on the activity monitor but when using timecode I'm experiencing audio dropouts and crackles and the CPU monitor fluctuates constantly but never quite hits the red. I have multi-core turned off, use music stored on my internal drive and turn wi-fi and all other Apps off. The audio problem is starting to drive me insane as my laptop should be more than powerful enough. Is anybody else experiencing anything similar?

Well some good news, at least for me. 2.5.1 seems to, for now, have resolved my CPU issues. While it's a little more load than what < 2.5 versions had, it stays well below 50%.
Reda Holdsworth
24.07.2012
Well after hours of tweaking just about every setting on traktor & my computer to run high performance. I'm running smooth as can be. Very happy. Going to wait to install 2.5.1 I have 3 very important gigs in the next 2 weeks. No reason to rock the boat...

Thanks to everyone here that had suggestions. Not sure what setting made it work correctly. It was the whole collaboration.

What is even more odd is I am seeing comments on both Mac and Win platforms. And it seems of little consequence if you have a F1, X1, or anything that matter hooked up.

Pre 2.5, my CPU load would never peak unless I had other apps open like Photoshop, Illustrator, etc. I can do a clean reboot, open Traktor, and it's going full tilt.

22.07.2012
I've had huge problems with this, this week. Very frustrating. Things are almost OK with the F1 unhooked.

I'm in the final round of a Dj competition Thursday & it looks like I need to use straight vinyl to be confident. I don't understand. Was working fine after update & all of the sudden i'm in the red or overloading...

I sadly have this issue as well. No external drive. Tried toggling multi-core. This is clearly a bug that Traktor needs to address.

Wow, worked for one gig, now I'm working on cue points and it is worse than before, wtf.

There is something very strange going on under the hood in traktor, buts its not anything new.. I've noticed the following observations from traktor pro v1 onwards:-

Having keylock on can cause the CPU load to increase, whether or not the deck that is locked is playing, or even has a song loaded!

Turning on an effects unit for a deck can cause the CPU load to increase, whether or not their are effects even loaded on that effects unit (let alone active), and like the keylock issue, regardless of whether or not there is even a track present, let alone playing on the target deck.

With no tracks even loaded, with all decks keylocked, and all4 effects units switched on on every deck (although the effects themselves switched off), I can get my CPU 'idle' up about 30-40% on my laptop.

I certainly wasn't casting aspersions in your direction. You relayed something that sounded plausible in the hope it might help ppl. I'm glad people like you share what they know. I just get annoyed when people post nonsense as fact on blogs. The fact of the matter is that there is likely a bug in the code that causes the use of multicore option to incorrectly handle how it processes data. Some people have had positive results with it turned on (not me) but most have not. I'm gonna guess that primary coding is done on OSX and then ported to Windows. This is often why you see disparities in different platform versions of the same product.

Rainer over at Traktor Bible has this documented on his site under the Traktor Bugs sections:

MULTI-CORE SUPPORT LEADS TO HIGH CPU LOAD

Several users experience a dramatically higher CPU load in version 2.1.1. Sometimes it can help to disable the multi-core support on Preferences/Audio Setup. If this does not help, you should go back to version 2.0.3.

Issue in: Traktor 2.1.1, 2.1.2 (?), 2.5.0 (?) added on October 4, 2011
Fixed in: unknown

Note for 2.1.2/2.1.3 I leave this bug in the "not fixed" section as there are still Traktor users seeing a high CPU load in general, and some while Multi-Core support is enabled.

Note for 2.5.0 It is still difficult to make a general statement in regard to the higher CPU load. Traktor 2.5 users make different experiences. Some don't see much changes, some see improvments, some see a higher load than in previous versions. And, the Traktor versions cannot be compared, as Traktor 2.5 and the remix decks introduced much more new functionality, which of course needs more CPU cycles. As long as a higher CPU load does not cause any audio problems, I would not be worried too much.]

Most of you know I am the guy who did the Kontrol S4 Windows optimization diary thread and have written a few articles for DJTT on this subject. The machine I use does have some grunt with an i7 and 8GB running Traktor on a dedicated Win7 partition. It uses less than 800MB to load windows and has run every version of the Traktor since the [much maligned] S4 version, flawlessly. Well, it did up until 2.5. The difference is considerable. I had to go from 5.3 to 5.7ms and to be honest, I won't be utterly surprised if I have to go up a level again once I start doing stupid stuff with the F1.

Whatever people believe about NI, they aren't fools and will no doubt be looking at the load issue. There might be an update in a month or 3 months - who knows. I am not stoked with the situation at all and if I wasn't planning on bashing some pretty lights I would roll back.

To those of you who have a perfectly well running system prior to 2.5 - I wouldn't waste an inordinate amount of time trying to make adjustments to your machine. Obviously the wifi/bluetooth/aero/etc should be off but it's likely you are already doing that. If not, go back and read the diary post, it's a sticky in the S4 community .

For now....we wait.
I am just letting you all know what I read and what I discovered with Traktor Pro 2 a year ago. When I turned mulitcore on, my meter spiked up , turned it off and it went down. My cpu load was at 1/4 before I turned it on so it wasn't like it was bad. I figured that was the only logical reason, telling Traktor to use all cores will cause the CPu to load up resulting in higher CPU usage but this begs the question what is multicore support good for then and why even have it if thats what it does? I have quad core, my latency is 10.2 overall, sample rate at 256, and everything runs fine so the multicore thing doesn't bother me. Its that old addage. "Doctor, when I do this it hurts" Doctor replies, "Well don't do that"

Absolutely! I could imagine managing the distribution of tasks to the different cpu cores could take up a little bit cpu power but that should be almost zero to none.

Traktor appears to be a fancy wig slapped on an ugly woman's head. Certain things - scratching with the high quality key lock on for instance - utterly cane my CPU and I'm using an Ivy Bridge Core i7 3770k. It's horribly optimised.

"The Multi-Core Processor Support lets you turn on or off the Multi-Core functionality of Traktor. Be careful with this one. If you’re running Traktor and ONLY Traktor and have Multi-Core processing on your computer, then turn this on. If your using other real time applications with Traktor or don’t have multi-core processing on your computer, make sure this is turned off as it can cause CPU issues."

I get this same problem when assigning effects. I start out mixing everything is smooth then the minute I assign any effects I get this loud pop sound then evertything goes back to normal. I have noticed higher loads as well. When i run latency mon it says everything is fine and but after a while I get slight clipping and load spikes for no reason. I have my PC optimized and never had any problems
I believe I'm going to have to switch back to traktor 2.1.3 or something I just don't trust 2.5 right now.

Some people have reported better results turning it off in Traktor. It would be nice to know the technical specifications of a multi-core processor use in Traktor. What advantages is it supposed to have over not using it and why?

Why is it recommended by some that multicore be turned off? Programs have been built around dual core computing for a while now, and trying to get one processor to do an amount of work is going to result in higher loads than having two to four split the same amount of work.
Rey Holubar

Try turning on the multi-core processing setting and also make sure your sound card driver is the newest one. There were driver updates with 2.5. Also, should you have more than one selection of sound card drivers in the Audio section of the Traktor preferences (Windows has 2), try them all out. Restart Traktor, when you make any changes too.

Lots of luck!

What was your latency at before? 7.6 is pretty good. If you're doing straight mixing, and some hotcues, then anything under 20ms is good. For any DVS, or cue point juggling you'd want under 10ms. I also heard from a lot of people (and the review on here) that Traktor 2.5 had significantly less CPU load. I didn't notice any change, but my CPU load was kind of high to begin with. I have to set it between 11-12ms otherwise I get dropouts.

This is affecting me as well, I'm running a brand new S2 on a MacBook Pro with 2.5. My CPU load goes through the roof and the audio cuts out. I do not have the multi-core processor enabled, and my latency is around 13.1 ms, I have a the biggest gig of my life sunday, and needless to say there is NO Way i could play a set like this!! Anybody have any idea what the problem could be? Any help would be much appreciated!

Hello,

I am having the same problem. I turned down the sample rate and now it seems to be fine - but I did not have any issues until today which is strange. I started up my macbook pro after work today and I could not even play a track without it lagging.

I am using the Traktor control s2 with the newest Traktor 2.5 software.

Any idea what could have happened over evening ? I did not do any updates as far as I am aware.

Fx banks assigning are getting me too, wasn't an issue before.

Not sure how these things fall through the beta?
Leeanna Ayla
02.06.2012
I've found that on occasion I'll get some drop outs when assigning fx banks to decks the first time. If I go ahead and assign the banks on then off when I fire up Traktor I don't have any issues.

I was having terrible issues with high cpu load causing popping in the audio playing from Traktor. I found that my F1 had key lock engaged on all 4 slots, which was contributing significantly to the overall load. Once i turned them off the load went down to back under a 1/4 which i believe is a perfectly reasonable amount. I can control the remix deck output with timecode vinyl, and scratch normally with the buffer size down to 128 samples and the fx turned on, without the cpu peaking out. I believe that's about the most the most demanding task i could ask the program to perform, so that seems to have been a good fix for my problems.

All the other things you had tried (multi core support etc.) also made no difference to me. The key lock (along with making the buffer size huge, which is clearly a useless endeavour) was the only thing to dramatically reduce my cpu load.

@OP, do you have key lock turned on in your track/remix decks? It seems that this feature is (or has become, i don't know whether it was the same in previous versions...) really cpu hungry. If you do have a remix deck active, it seems an understandable load. Whereas you would only have been able to have 4 keylocks max in previous Traktor versions, you can now have that amount engaged with just one remix deck...

Hope this is a help to anyone else suffering the same kind of problem
