i play league of legends with my nephews about every day, and we're all on skype it's great fun and all, but every 30 minutes or so, it lags a tiny bit (a few secs , or 15 secs). this can be very very annoying and even ruin the whole game. I know one of the specs of the laptop they play on, and it's really good, especially good enough for LoL; i5 cpu, NVIDIA GT740M graphics card. the other PC/laptop they use, I don't know, but since they both have lag, I don't think this is the problem. if their internet is too slow for LoL/skype at the same time, wouldn't it lag every minute? this is not the case.... we've even tried raidcall instead of skype, because we heard raidcall might use less bandwidth. it was better, but they still lagged (less frequently we think) what could be the reason? how can we test this? is skype that bandwidth intensive?
