Popular European/Russian server player and one of best players overall Skill4ltu has released a new video, that sheds some insight to a relatively new problem in World of Tanks, short lagspikes that seemingly appear only when certain conditions are met.
Without jumping into conclusions, Skill has provided enough evidence that the problem could be brought to more light and an official response would be given. The video is definitely worth the watch to form your own opinion on the matter.
