<shamelessly cross-posted from another forum, but this issue will likely need to be seen by many eyes to get some good feedback on, my apologies in advance>
All,
I have had a strange micro-stutter issue for as long as I can recall that flies in the face of traditional assumptions.
Unless I am playing a game with VSync *enabled*, I get severe micro-stuttering, *even* if the framerate is locked at a relatively high number, such as 70 (using Precision).
-I have been gaming for 20 years and know what micro-stutter is, and this is almost assuredly it.
-I have 2x GTX 580's and a 2500K at 5 Ghz
-It happens in all games I have tested, regardless of age
-I run Kaspersky AV and run a clean system, malware is not a likely candidate
-I monitor my temps at all times, so no need to even ask
-This problem has persisted for over a year, across multiple OS installs / driver upgrades
-The problem gets more pronounced as the framerate is lowered, but even playing at locked 70FPS is very jerky.
-The problem is completely resolved by enabling VSync, 100% of the time.
Why is this a problem? Well, because some games are locked @ 30FPS, and they become utterly unplayable due to this issue. Subjectively, it feels like playing at 10 FPS when I am actually running at 30.
Thoughts? I have found one other post on the web from a guy with SLI 580's and it sounded like he had the exact same problem as me, but it had no noted resolution.
