Patch 5.0 performance problem

Hi guys i have big performance drops after latest patch 5.0 no idea why, it ocurs when on map is lot of unit and then game is unplayable (FPS nonexisting) it was ok before this patch , someone have same problem or solution ?

well its the game’s problem. Its old and not optimized for multicore/ threads CPU. I have same performance issue when playing games. FPS dropped to like <5fps in battles in team games. and somehow Blizzard still hasnt fixed this issue… :((((

i get it but it was without problems before latest patch , so how is posible that it was ok like week ago and now its unplayable.

um it could be an issue with latest patch. Do you have game lag stutter when boxing or selecting units?
And what is your PC specs?
