100% CPU usage?

[panthera uncia]

Got back into this game recently and I've been noticing my CPU usage is oddly high, often pegged at 100%, while my GPU usage is much lower at about 54% - 89%. I don't think this is right, since this a PS5 port and the PS5 uses AMD hardware, much like my PC. Is there a setting that I need to change to lower the CPU usage to a more reasonable level or something?

For reference, CPU is a 7800X3D while GPU is a 7900 GRE.

Yes, open task manager, right click Helldivers 2, click Go To Details, right click Helldivers2.exe thats highlighted and click Set Affinity in the drop down menu, untick the box for CPU 0 and click OK, I was having the exact same issue with the same CPU and after doing the above CPU usage is around 15-20%. You will have to do this every time you launch Helldivers.

Theres some kind of issue with windows scheduling and the AMD architecture, supposed to be an issue exclusive to old hardware but seems to make a difference even on the new.

I'm seeing CPU use creep up to and stay at 70 to 90 per cent on my old Intel I5-9400F. This behaviour is new to the Squid Update, so I'm guessing there are changes to handle the hordes or something. Hopefully Arrowhead can patch it once they return from their holidays.

AMD hardware is kinda fiddly...

There is even the recommendation to disable core 0, you know.

Well that's annoying lmao woulda expected differently considering the PS5 is also an AMD machine

Someone else pointed out that this behavior is new to the squid update, I am hoping it gets fixed after the holidays are over. I don't recall this game using this much CPU before.

Confirming that unchecking CPU0 for the game mitigated creeping System Interrupts "process" load. I had this issue since end of January, long after squids happened.
