CPU spikes every few seconds

Adding one here even if saw people reporting it.

Since 2/3 days now, i start to get CPU spikes.
can play for let's say 10 minutes until it starts to come and then it occurs every few seconds.
Needed to exit the game and then relaunch it, was solving it but since today It is getting worst and worst.

Same here... just standing in hideout cpu spikes and hitches the game. No idea one is causing the random spikes.

Oh apparently it could be chat causing the spikes even if tabs are hidden. Clearing chat or switching to empty tabs seems to fix it for some.
