So, I upgraded from an RX 6600 to an RTX 3070, and since then this problem started
Opening some plugins in fl studio cause crackling in the moment I open them, but this crackling goes away.
Ill list the problems so it will be easier to understand

Hoovering the mouse arround sample channel causes a little bit of audio crackling

Opening Fruity Parametric EQ 2 causes crackling, but only if in full screen 4k (2k and1080p doesnt have any crackling at all), but if I disable the graph it stops crackling, but as soon as I hover my mouse over the buttons on the graph it starts crackling again

Here's a video of the problem so you guys can see what I'm talking about: Fl studio crackling problem - YouTube

Changing the buffer size doesnt change affect nothing
I also tried checking DPC latency with LatencyMon and my latency is arround 60/100 all the time, so IDK whats happening, here's my PC specs:

x570 TUF PLUS
Ryzen 7 5700g
RTX 3070
2x8gb Team Group Delta RGB RAM 3600mhz (OC'd to 4000mhz) CL 18 22 22 42 64
1 NVME SSD gen 4 with dram cache (1tb)
1 NVME SSD gen 3 (512gb)
1 SATA SSD, 1tb
Power Supply: XPG Core Reactor 850w

FL Studio 20.9.2 (Build 2963)

Windows 11

Already tried Nvidia studio and gaming drivers, no change at all, already tried unninstalling geforce experience and setting low latency mode on and off

if you guys need any other information just ask me, thanks

 

not sure if you tried this yet but have you uninstalled the nvidia audio drivers and switched back to the default windows one?

 

yep, I also don't use neither windows or nvidia audio drivers, I use focusrite drivers only

 

I didnt get it, you mean deactivate em? which effects?

I did, it's on the video from the OP, here: Fl studio crackling problem - YouTube at 01:07

2- yes, I have no crackling in any other application
I also don't have any usb hub or wireless device

3- Yes

 

Hallo @Kuuhaku - Wow new graphics card and the problems start.
Sorry - I don't like watching videos that much - I watched it now.

Increase step by step from 64 to 128 then 256 --> I recommend Buffer lengh 256smp

Fl Studio 21 - Producer Edition v21.0.1 (build3348)

Well, I tried the new driver and it seems to work, after unninstalling the old one with DDU and installing this the crackling stopped on parametric eq 2

 

Well then, keep the driver. Do you have any other crackles or pops?

 

randomly while I'm using FL I get some crackling, but nothing on the level of what I was having before, its totally usable now

 

Nvidia driver (nvlddmkm.sys) has high latency, that's a known issue. Certain versions reduce and certain increase it unfortunately.

 

go in device manager and disable all audio driver from nvidia or microsoft

Just use your dedicated asio interface driver

PeaceR

 

Well, it seems that the problem was the "Power Management Mode", when I set it to "prefer maximum performance" and restart the PC shows that behavior, but setting it to "Normal" and restarting gets thing back to normal

I was just about to reply that you should set it TO 'prefer maximum performance" for all real time apps - is that what you meant to write perhaps? In the Nvidia control panel you can set this for each individual app (program settings tab next to global settings) so it will only kick in when needed. setting this for reaper, bitwig etc plus changing the windows power plan to maximum performance solved all my DPC latency issues.

 

well, if I set prefer maximum performance globally and then specify fl studio to have normal performance I get the problem anyways, I guess I'll have to use it in normal mode

Setting it to normal didn't introduced any dpc latency issues till now, but I'm gonna do some testing

Also, it seems that an option on Nvidia Control Panel break the 60fps limit on OpenGL applications, and letting they have 1000 of FPS introduces crackling back again, so I used the program specific setting in "manage 3D settings" to allow fl to have maximum of 300FPS, this got rid of crackling again
