Jonny6String809 Posted July 23, 2020 Share Posted July 23, 2020 Has anyone else that has picked up the Nexus noticed insane CPU usage? I'm used to the last several versions of iCue consistently utilizing 5-6% of my CPU, but since installing the Nexus the CPU utilization from iCue is constantly 15-20%. If I unplug the Nexus it instantly goes back down to 5-6%, plug it back in and it's back to 15-20%. It's actually enough that my CPU (9600k@5.1) won't throttle down and is constantly at max speed.

c-attack Posted July 23, 2020 Share Posted July 23, 2020 I doubled up from 3 to 6% on a 8700K. +10-15% more seems like a lot. Anything unusual about what's on on the screen? Mine are all graph monitoring system temps. Link to comment Share on other sites More sharing options...
Jonny6String809 Posted July 24, 2020 Author Share Posted July 24, 2020 Nothing unusual at all. I haven't even made any custom screens yet. I'm used to seeing a few percent increase if I have the dashboard open in iCue, but nothing this crazy. I do have a lot of other hardware run by iCue. Commander Pro, H150i, K95, Nightsword, MM800, ST100, Void Elite and the Asus MB plugin. This spike only happens with the Nexus plugged in though. The second I unplug it iCue is back down around 5%.

no0va.bhamade Posted July 25, 2020 Share Posted July 25, 2020 i just got my nexus and installed it and everything my cpu (AMD Ryzen 7 3800x) jumping between 4 - 8 % usage and temperature never below 43 degrees (usually it idles between 33 - 38) so it's a bit disappointing might ask for a return and refund if it didn't get fixed within the next 2 weeks!!!

BahamutxD Posted July 25, 2020 Share Posted July 25, 2020 If you want less CPU usage from iCUE you need to remove devices not keep adding more. Seeing how Corsair doesn't mention this issue at all I wouldn't expect any move from them in the short term. Link to comment Share on other sites More sharing options...

That's my feelings as well. When the end of my return window starts getting close in a few weeks, it may very well be going back. Its function doesn't justify the CPU usage. I mainly got it to monitor system temperatures while I'm gaming. Kind of defeats the purpose of monitoring an overclocked rig when the monitoring device eats up the extra FPS you gained from the overclock and then some.

Corsair Employee Corsair CJ Posted July 28, 2020 Corsair Employee Share Posted July 28, 2020 Hi all, thanks for bringing this to our attention. Please note that the increased CPU utilization is likely due to updating the screen at roughly 24fps over USB (which largely relies on CPU resources). Animated backgrounds/buttons as well as monitoring widgets will also likely play a factor in increased CPU utilization as sensors need to be polled and onscreen items need to be rendered. If you require any technical support with your iCUE NEXUS, please contact our support team at https://support.corsair.com where they'd be happy to assist you.

Xrat3d Posted July 29, 2020 Share Posted July 29, 2020 I got the same behavior but found the problem... I have my Nexus plugged into the usb passthrough of my K95 XT, but the cable that goes into the PC, was plugged into a USB 2.0 port, as soon as I switched that to a USB 3.0, my CPU utilization came from 10% down to 5% ... hope this helps.

Corsair Employee Corsair Nick Posted July 31, 2020 Corsair Employee Share Posted July 31, 2020 Thanks for the additional input, this should prove useful to our validations team for testing. I'll go ahead and pass the info along. Link to comment Share on other sites More sharing options...
Timb320 Posted August 10, 2020 Share Posted August 10, 2020 FYI Mine is connected directly to the PC via USB 3 port and averages 8% CPU and idle CPU temps hover between 33 and 47 C while Icue is running, normally its around 31/33. I would recommend Corsair add a polling interval setting so users can control how often icue pols devices and updates the nexus screen. Link to comment Share on other sites More sharing options...
Strolla Posted September 20, 2020 Share Posted September 20, 2020 (edited) Same here, just got my nexus too. And same as Timb320 above. iCue using higher cpu usage. increasing idle temps. Edited September 22, 2020 by Strolla Link to comment Share on other sites More sharing options...
Corsair Employee Corsair Nick Posted September 21, 2020 Corsair Employee Share Posted September 21, 2020 Our developers are still looking into this, and we'll provide an update once we have an official word. Link to comment Share on other sites More sharing options...
Strolla Posted October 17, 2020 Share Posted October 17, 2020 Still happening when using monitoring widgets after 3.34. Does not even need to be on current viewing screen. If you remove all monitoring widgets from iCue, usage drops back down. Pretty bad since this is sold as a monitoring tool. Link to comment Share on other sites More sharing options...
Corsair Employee Corsair Nick Posted October 22, 2020 Corsair Employee Share Posted October 22, 2020 Thank you for the feedback. We've implemented some improvements in 3.34.161, but will be continuing to make further ones to improve the CPU usage in further updates. Link to comment Share on other sites More sharing options...
Syranetic Posted October 22, 2020 Share Posted October 22, 2020 I have 11+ (and growing) devices in iCUE and I just got my Nexus. I don't see what people are complaining about, when controlling so many devices, USB polling for the screen, the RGB profiles... I usually see around 5-10% CPU usage. It is what it is... should Corsair always be looking for more efficiencies? Of course... but you can't expect there to not be a hit to your CPU running all this stuff. In most cases it shouldn't matter anyway, it's not like games are using 90% of all your CPU cores. Link to comment Share on other sites More sharing options...
