FL Studio poor CPU / Audio performance compared to Presonus Studio / Cubase. How to optimize?

Not all DAW's are equally efficient, and FL is no longer in the top tier these days. There are things you can do to improve the situation, but it seems like you're aware of them, and yeah they don't work miracles.
I know your pain, but this is a big part of why Steinberg is Steinberg. Probably nobody on earth cares as much about core engine internals, save for maybe Reaper. Basically, not much is going to hold up well against Cubase in a strenuous performance test, but compared against other things like Ableton, FL's performance is very respectable.

That looks like a bug with one of the plugins you are using. Plugin behaving badly.HREQ wrote:

Can FL Studio play back tracks that is not record enabled/monitored at higher buffersize than tracks that is armed or active for monitoring?
If not, try to disable Asio Guard in Cubase and compare the CPU performance between the programs.
If FL Studio has this capability make sure that both programs buffer settings match for both monitored and not monitored traks as close as possible.
I’m not a FLS user so this is just an input with a possible reason for the noticed difference in CPU usage between Cubase and FLS.
Studio One got this functionality recently. If you argued on the forums that Studio One had worse CPU performance than Cubase or Logic, before Presonus implemented the «Hybrid buffer engine», you got bashed by ignorant S1 fanboys who tried to claim your system was wrongly configured/optimized and that S1 was performing better or at least as good as any other DAW in any given situation
This thread looked alot like thos old S1 threads, OP observations denied by ignorant fanboys and vendors, so I had to jump in and mention this possible difference between FLS and Cubase/S1.
If not relevant, so be it

Did you watch the video? That is definitely a bug.Reefius wrote:LOL, typical IL response, it's always a bug in other software because FL Studio is perfect
I also invited him to work with us on techsupport to get this fixed.
How you can turn that into a negative, I have no idea.

Did you actually read the whole thread before watching the video and blaming it on anything else than FL Studio?Image-Line wrote:Did you watch the video? That is definitely a bug.

The issue is about FL Studio poor CPU performance, issues that don't exist in other DAW's, and you simply blame it on buggy plugins? So tell me, how come these 'buggy plugins' work fine in other DAW's?
Maybe it's time to start over from scratch and build a DAW that's actually optimized for todays CPU's. That old Delphi code from 1998 is hopelessly outdated.

same problem with all the 'HARDWARE EMULATIONS' based plugins of https://www.plugin-alliance.com/en/products.html , personally I've built a desktop PC just for FL
and the problem has been solved ... for meMSI B350 Tomahawk

Reefius get up off the cactus and sit in some aloe vera. FL's performance clearly gets the job done, there's no moral obligation to meet some imagined CPU efficiency metric. The world doesn't revolve around you.

Whoever wants music instead of noise, joy instead of pleasure, soul instead of gold, creative work instead of business, passion instead of foolery, finds no home in this trivial world of ours.

Hi
To original poster:
Definitely work with the developers on this - they have requested you do, so what have you got to loose?
In my experience of beta testing a well known host program, they will look closely at your hardware, sound card and projects - I would be surprised if something doesn't come out of it that does not at least take the 'edge' of that CPU usage.
Although you can get some useful advice here ,as can be seen - you will also see a whole bunch of people get riled up!!!

I did. And my post was specifically about the video he posted. Did you watch it? It's a bug.Reefius wrote:Did you actually read the whole thread ...
Likely a plugin behaving badly. I base that judgement on approximately 17 years working in this industry and with the development of FL Studio in particular.
If you have issues, come to Techsupport and work through them with us.

I bet you don't even own FL Studio, or maybe you bought it when it was still fruity loops and you didn't like it? Or are you on Mac maybe? What fantastic and flawless DAW do you use? What ever is the reason for your anger towards Image-Line, we get it already! Yes I own FL Studio and I like it, all though it's not perfect. I stopped updating it since ver 12.4.2 since 12.5.1 gave me all kind of troubles with plugin scan. I own Bitwig to and it's not perfect either. I just bought Reason 10 and Studio One in the charity auction. Let's see how good they are. What I don't like is people ranting page after page and it doesn't help OP at all. It doesn't make me any fanboy what so ever.Reefius wrote:I never understood why this glorified drum sequencer has such a huge horde of fanboys
