Intermittent momentary game freezes/stutter
Not sure what's going on with the game but for a bit now I've been experiencing random momentary pauses in the game where everything on the game freezes, then it "catches up". I haven't changed any hardware, and I've kept up with Windows 11, BIOS, and driver updates. Hardware-wise itself, these are a relatively new occurrence, and my system is well beyond the recommended specs with a non-overclocked 13700K, 48GB of DDR5 running at non-XMP 5600, and a 4090. CPU and GPU are water cooled and temps have never been an issue. Game is installed on a raid array of nvme ssds. I typically use wifi, but I've run a really long lan cable through the house and the issue occurs that way as well. I generally have the bgm music off and am just listening to sound effects. I can't recall if those pause as well but given, I can't input a skill to generate one, I'm reliant on being around another player doings something while it happens. It's happened while I'm alone in my house crafting, solo doing fates, during roulettes and trusts, even during the afk gpose style camera moving between other pcs, nps, etc. I don't think the number of others or the number of effects triggers this. And as it even occurs during the afk gpose hopping screens, it seems regardless of the amount of input I am putting into the game (I've watched it stutter a few times already while typing this and registered as afk, where the gob npc it was targetted on head would stop briefly during its head bob and then resume at a different position).
Are there some specific settings I should try and change/disable to try first? Currently I run the game at Nvidia's recommended settings for borderless windowed mode at 2560x1440 on one of my 2 monitors. I've tried a ton of different things already, such as turning off XMP, and the BIOS updates were for the Intel microcode stuff.
My wife's system is also encountering them and has a different setup entirely, save running at the 2560x1440 resolution and being installed on a nvme ssd. That system is a single monitor, 32gb ddr5, 13400 (aio), with a 4070 ti (oem air cooler). I don't know the frequency she's encountering them as she's in a different room. She's using a physical lan connection but was previously using wifi. Changing to a physical connection made no improvement.
