I have been getting some small lag in the past few days. It is definitely not ping related, since my ping/loss/choke are all good. The lag is weird. Once every few seconds (between 20s and 1 min) there is a small stutter step, i.e. it doesn't read the command, be it walk forward, change weapon, whatever.
Once possible cause is that my SV value fluctuates a lot. It changes between servers, but it can be between 2-4 on one server and between 9 and 14 on another server. The number doesn't really matter though, since there is the same when sv is 3 or 10. The std. deviation (+-) is always very low, and so is the var value.
I have re-installed the game and stopped all AV software running but I still get the same problem. My FPS is 200 stable (capped at 200) and I have a good enough machine: i7 4770K @ stock speeds, 280x for graphics and a 126GB SSD. FPS should not be an issue (contrary to what I read online).
Does anyone have any potential solutions? Thanks.
