I have been experiencing this stuttering issues since 1.0.6 patch and right now, I have to browse all over this forum to fix this problem. I have tried alot of things in my NVidia control panel but no good so far. At the greater extent, i also went to buy a 16-gig flash drive and did the symbolic link. The single player mode worked better but still stuttering from time to time. Which led me to think that it has something to do with this patch and code from D3.
I hope you guys can help me out to determine which causes the problem. And if you have some settings that worked on you, please share it here and i'll have a try.
I also submitted a ticket to support.
Thanks and have a great day!
