Months ago, out of nowhere, I developed a frame stutter despite having high fps.

I have my fps capped at 250, but without the cap, I get around 1300.

My processor has six cores, and I have 8 gigs of ram.

Before this development, everything ran smoothly.

Other games still run smoothly. For instance, I can play CS:GO and Skyrim without any stuttering.

The stutter is not dependent on having lots of players on my screen or being in certain areas. It even appears on the character loading screen sometimes. It occurs approximately every 10 seconds, although sometimes slightly more often. The stutter affects the displayed fps in no way, shape, or form.

It appeared spontaneously, in the absence of any changes. There was no preceding event, I didn't alter anything before it began, but suddenly the stutter developed for no discernible reason.

I've updated my graphics drivers, and it didn't help. I've reinstalled Freestyle Gunz, and it didn't help. Resolution does not affect this - it is consistent throughout all resolutions. Windowed mode changes nothing. I have always used Archetype's config. My system is free from viruses.

Does anyone have experience with anything like this?
