Agents, I can't say this is definitive - but after two back-to-back days of multi-hour freeze-free / crash-free sessions since removing a Corsair Commander Pro and iCue software from one of my PC systems.... it may be a factor for some of you. I also removed a Corsair H100i 240mm AIO and replaced it with a Noctua CPU air cooler and fans. So, no Corsair LL fans or even case Corsair LEDs were installed for testing.
While I've never used the in-game iCue integration, it seems like the USB resources and underlying iCue application seems to eventually cause The Divison 2 application to freeze and/or crash. Now, whether the Development or QA team at Massive Entertainment care to test and resolve with their game application or their partner Corsair and the iCue application - is up to them.
I should also note, that a fellow clan member is also testing the same theory and his system has also been freeze-free / crash-free for three days now since removing iCue and all Corsair hardware - whereas previously he would experience multiple freeze/crash instances during his gaming sessions with The Division 2.
I'll continue to update this post with my testing or as soon as I get a freeze.... but at the moment this seems to have resolved the long-standing issues I've had with The Division 2 on PC. Swapping out pretty standard industry hardware from Corsair and their iCue software clearly won't be a solution for many, but I wanted to share my findings. Also, whether other RGB lighting ecosystems like onboard addressable 5V or RGB 12V are a factor in the in-game freeze/crash is unknown to me at this point.
