So, however I run CSS (different settings in options, multicore rendering on or no), game tends to lag for a few seconds from time to time. Weirdly this mostly happens on DE and nowhere else. If you think the problem is caused by my laptop, you are mistaken, it is 200 years forward from CSS's time. I do not have that lag on UKCS servers, where I also play.
So, my point is actually that do any of you know about the problem or experience the same? Game used to lag on my prev. laptop when multicore rendering was on, but when I had that turned off CSS was excellent.
(the problem is not caused by my internet connection too*)

So, any of you know what I am talking about?

I don't have any lag on the breakfloor server, though the ping sometimes raises up to 100 for a few seconds.
Oh, and when I spectate other people, it also laggs, haven't experienced this on other servers.

This lag may due to the update last year? Maybe more bandwidth is required?
