Bitwig 2.4 - CPU Spikes

[fwsuperhero]

Hello!
I bought new computer.
Dell Inspiron I5 7000 Gaming
CPU
Intel Core i7 7700HQ @ 2.80GHz
Kaby Lake 14nm Technology
RAM
8,00GB Dual-Channel Unknown @ 1197MHz (17-17-17-39)
Graphics
Intel HD Graphics 630 (Dell)
4095MB NVIDIA GeForce GTX 1050 Ti (Dell) 39 °C
ForceWare version: 391.25
SLI Disabled



But I experience much more unstable performance with Bitwig than ever before with much weaker computers (in 5% of time, just when spike / lag happens).
This is what happens random spikes, the heaiver project, the bigger spikes. Even empty projects create somes (cpu jitters change very fast for example from 4% to 16%).

Does anybody experienced and solved this?
Thanks

Yes and no, that's how it works, it spikes like mad, no cure for now.

This is the main reason I didn’t upgrade. Performance has gone down consistently, for me anyway.

Upgrade what? Bitwig? I had got great experience with Bitwig on my AMD laptopls that are just not enough for current standards. This is not about version but about specific HW environment that Bitwig doesnt use well.
But i have got glitchy experience now, with much newer hardware. It is very sad, i invested in Bitwig and Maschine jam because I was going to buy a new computer to enjoy its potencial to the fullest.
If there is any way how i can help the developers (debuging the jvm process etc) i will.

You mean 2.4 right? Or are you using a 2.5 beta?

Whenever I have this kind of problems is due to power management / throttling of the CPU.

this is simply not right. Bitwig is very stable and no issues here (other than I tend to get lost in experimenting when I was planing on composing).

to the original poster (and everyone else experiencing cpu spikes on windows 10 with proper CPU) you should be more than good with this PC as long as you take time into optimizing it but throwing in 8 gigs of ram later on will be a very good decision. at least the CPU is beyond capable of using Bitwig. Bitwig has been very stable and stable on with my 7700HQ processor on heavy projects.

first of all, read this link carefully https://bandzoogle.com/blog/20-ways-to- ... production. there are more links out there but this has many of the important factors to get you started.

if you still experience CPU spikes after optimizing windows for audio use, than you need to look into Windows drivers and DPC latency - download Latencymon. keep it on for some time and take a look at what drivers are causing highest DPC activity in your device monitor, than deactivate some drivers. below is a link which is a good start for everybody with cpu spikes issues in any DAW and it will tell you about which drivers are most often the cause.

my average Lenovo laptop was literally useless when I purchased it brand new even after optimizing it for audio by every guide i found online; I had no idea about what was going on. after searching the internet for a while I deactivating the WIDI driver which solved the problem, and than deactivating other drivers for useless crap such as bluetooth, webcam etc made things even better. often times video card drivers cause DPC latency, than you need to google some more but usually other people have experienced similar issues before you and have found help / shared resources online.

good luck!

Yes (like the poster above), I found that systematically checking through the power-management settings and drivers etc made my latency far more stable (I *have* to disable my wifi/network adapter for example). I used this ebook and what I found valuable was it actually explains the mechanisms behind latency spikes as well as the practical steps to eliminate/minimise.

Well, it is right here and I'm not alone there either, YMMV, it spikes every time you launch something, not every time spike make glitch, but if you pull out DSP graph you can see that clearly. It runs stable either way, but it spikes.

Ouch, I'm sorry! First of all, I meant should be stable. But random and frequent CPU spikes used to be a big problem for me too as for the OP, but I got rid of them by deactivating the correct drivers in device manage so I hope that will help people experiencing crackles and pops in Bitwigs audio engine.

But yes, I've also noticed CPU spikes when opening new project if I recall right - but it happens every time when loading up Phase 4. This is not random spikes and not not a problem in my case, and I can't say I've noticed worse CPU performance with Bitwig 2.4, that's why I posted about DPC latency.

I hope this behavior can be improved if we report it.

Thank you everybody!

I experience CPU spikes very often and randomly, this is not problem of opening something.

I have got weird feeling (and DSP meter in 95% precent supports that) that situation is much better when i got into airplane mode. But i am very happy for your links and advices. I am more LINUX guy and i didnt have to configure windows before. I had always more problem with Linux and Jack performance than with Windows native drivers. I forgot to say that i have also external sound card so there is no problem with audio drivers.

Btw. I know that i should upgrade RAM and I will. But it shouldnt be the reason i think.

Thank you again everybody , i will get back when i go through every tip here.

No, sorry... Corrected

Whenever I have this kind of problems is due to power management / throttling of the CPU.

This is what i have thought but I have tried some alternative Power Manager that should keep CPU performance stable and it didnt help. But I will investigate this problem more, thank you.

Newer intel processors are really a pain wrt to power-saving management. They auto-overclock and surpass their own power limit specificition so they will do well in benchmarks; however this is time-limited and then you'll suffer from instability.

I'm unhappy with the amount of tweaking needed these days.
