Hi all i seem to be running into this problem day in day out im farely new to pc gaming so i hope i make sense in this problem i have here goes,i play games like D3 and WOW mainly but at times play all of the CODS.When i play WOW and D3, i play with VSync on as it stops screen tear and just seems smoother over all for most of the time my fps is locked at 60 but as soon as i run into a mob it drops to 20-15fps and the same on wow on 25 man raid, my system as far as i know should play these games with ease i play with high settings but ive also tried with low settings and get the same problem,the wierd thing is i can play games like BF3 and MDW3 all on max settings and i hardley lose a frame very smooth and a pleasure to play but unfortunatly COD and BF3 arnt the games i love to play the most, this problem is very annoying knowing my system shouldnt struggle playing WoW and D3.Here are the specs of my machine also 1 last thing id like to mention the stutter seems to be in D3 more than anything else i can be walking along and the game starts to stutter hope this all makes sense and someone can help ty.
