Frame pacing problems - stutters

[AUSSIEPATRIOT]

1. At Steam, try the public_beta of Soma. It's supposed to fix frame-rate issues.
2. Have you verified game files via Steam?
3. Disable all background applications (f.lux --> known to cause gamma resets, OSD from Afterburner etc, game boosters and stuff like that).
4. Try Adaptive or OFF vSync. In my experience with a 660 vSync was causing stuttering and Adaptive/OFF did not but there was screen tearing all over the place. In the end I just ignored it even though it was really annoying at times.

1) Public beta does nothing for me, tried several times,

2) Verified many times as well a fresh download and install last night,

3) Yes I have tried numerous times with Afterburner not running and running - both result in stutter

4) Having Vsync on/off makes no difference

I'm going to post a vid soon to showcase the stutter.
