What's the cause of consistent stutter in Quake4 across PCs? - Assorted Food To Avoid for Diabetics

I've been playing Quake 4 since it's release day, and I've noticed there's either a v-syncing or caching issue where the framerate seems to jump for a split second every second or so, I've been calling it a heart-beat all these years.

I first noticed it on my ATI X800 Pro many years ago, assumed it was some weird gpu thing and didn't think much of it. Later I got a GTX 460, while it was much smoother, this weird ticking still occurred. Now I'm using one of the fastest GTX 580s ever made, and seemingly no matter what I do to the settings, I can smooth it out a little, but that micro-stutter is still there every second or so.

Did anyone ever figure out what this was? I've seen this on Intel Cpus, AMDs...Laptops...Desktops...Xeons...Opterons...With SMP, without SMP....I'm not sure what could be causing it outside of just plain bad code that never got addressed.

Why does my computer keep micro stuttering?

Micro stutter most often occurs when the rate of new frames doesn't quite match up to your monitor's refresh rate and vsync is enabled.
