Step 1: Run, Start Synthing, Start Gathering.
Step 2: Continue to do so - after 1-2 Minutes issue starts


Since the 27 Oct patch there has been an issue with a CPU usage spike which causes the game to lockup for brief moments - but only when moving, synthing, gathering. Whilst standing still and doing nothing the game remains running smoothly with no spikes or framerate drops.
I have to keep re-starting the game and computer until the issue doesn't hapen - this successful run happens around 1 time in six.
I run the game fullscreen and have a seperate cpu monitor - the second core of my i7-920 keeps spiking up to 100% usage and at that moment the game freezes and then continues about 0.25 seconds later. This happens about once every second and is obviously extremely distracting and makes it impossible to gather correctly as the minigame pointer is not smooth.

If any more information would help please contact me. I am happy to even supply a video if it would help.
