Lag and ping issues since patch 2.55

ok so i have been experiencing lag and stutter in game since the latest patch came. my ping will drop down to normal after i exit the game ans the problem seems to occur 30-40 mins in game. occurs all through out the day with no specific time.

i have checked my ping status during game and it would go to 900++ms and my download speed goes down to 1mbps or less but when i exit the game and restart it my ping goes to normal again. it has lead me to believe that the problem lies with the game.

have tried port forwarding, resetting router, called ISP etc but nothing seems to work. whatever happened to that patch kinda f'ed my game. i hacve also done trace rt while in game vs not. when in game it shoots up to 1000ms. problem seems to start AFTER i have logged on and have stayed for 30-40 mins and seems to go away when i restart but would start again 30-40 mins playing.

any solutions will be greatly appreciated.

Well i'm glad i'm not the only one having these issues since the latest patch. I play 5 metres away from my friend on the same server and network and she has no problems at all.
