Game causes FPS stuttering which affects the whole PC.

cool.. all the details weren't listed, so was just running down some of the usual suspects.

Are you running in a windowed mode (guessing so, since you have other windows over it in the screen shot). This game seems to suffer the same fate as XI did on some systems... full screen may resolve some of it if that is the case. If so and you want to run windowed mode, might want to double check the option about frame rate control when the game is not in focus (forget the exact wording, but it's in there somewhere). Some have even reported having things smooth out more if they run in borderless window mode.

Also, have you tried using another tool like Furmark, or maybe a different one with a DirectX engine like maybe the Last Remnant benchmark? Just curious if the micro-stutter is game specific, restricted to network applications (just like with XI, XIV can have jitter because of lost packets/bad latency), or more a systemic problem. Try to narrow it down better so maybe more people can come up with ideas.

I'm running it just fine on a laptop with a 670 in it (not the exact same card, but imagine some similarities)--but I'm on a much older driver version. I also had some weirdness that went away after updating my sound card drivers--it was to resolve an issue with the subwoofer flaking out in congested areas, but as a strange side effect my random black-screen/gold bars on screen problems went away as well. It's possible there could be something in the newer drivers you've been trying... SE games are notorious for that sort of thing (newer is not always the solution). I'm running on a 3.11 nVidia release... yeah, it's old, but it works. They have an archive of older drivers at guru3d.com if you want to turn on the way-back machine and try some of those older releases. Their driver cleaner works pretty good too if you don't already have one and have been cleaning up manually.

Just spit-balling, but it might be worth a shot, seeing as you've tried just about everything else.

Sorry that I was a bit spare with the information, writing down every single step I tried would be a very long text.

Edit: It wasn't the cause of my problems.
It looks like borderless Windowed slightly reduces the overall stuttering but it still happens.
My guess there is something wrong the code that manages if the window is active or not.

I could also exclude my GPU itself, I tried a GTX660 from a friend and the problem in windowed/borderless windowed mode still happened.
