Please note this will NOT fix your screamyx (aka latency) lag.
If your latency/ping drops to red (>600 ms) that's a problem with the ISP and the server's connectivity.
EDIT: Ignore if you're already using D3 installed on SSD
It will not improve any further as the issue is caused by HDD read/write bottleneck.This will fix issues like:
1) You're playing fine but then a group of monsters appear from the edge of screen. Your whole screen then FREEZES or all mobs moving in slow motion including your char.
2) Your display is fine but all of sudden (eg: fires around bridge leading to Siegebreaker) the display lags badly.
3) Your normally well behaving/good performance gameplay lags all of a sudden (without any additional tasks/programs being run)

SOLUTION (Windows 7 or Vista):
1) You will need (minimum) 16GB USB flash drive (or 16GB SD card). An 8GB flash drive will not work because it will translate to 7.45GB under windows, which is smaller than needed (7.7GB).
2) Copy the entire "MPQs" folder (7.7GB) from:
"C:\Program Files (x86)\Diablo III\Data_D3\PC\MPQs"
to your USB/SD drive. For me, it was "D:\" drive, so the final result was "D:\MPQs". It might be a different drive name for you, so just use what you get.
3) Rename the original "MPQs" ( located on your HDD) to anything you want.
now the tricky part ...ready ?
4) Go to windows start > and type the following in the search box:
cmd
and hit (CTRL+SHIFT+ENTER), which will prompt you to run command line in administrator mode.
5) Once in command prompt, type the following (make sure you have the right letter drive):
cd "C:\Program Files (x86)\Diablo III\Data_D3\PC"
mklink /j "C:\Program Files (x86)\Diablo III\Data_D3\PC\MPQs" "D:\MPQs"
***Note: you cannot "CTRL+V" in command prompt, but you can right click "paste" instead.
***if you don't like this command-line stuff (step 4 and 5) you can jump to windows XP solution, but you have to install an extra program.
If you get a message that says something like: "a symbolic link has been created .." then you did it right. Your done!
=========================================================
SOLUTION (Windows XP) also works for windows 7/Vista (no command-line involved):
=========================================================
Basically, we faked the location of the MPQs directory and relocated it to a flash drive with faster read response than your HDD.
Now, you should have read response times (RRT) around 5ms !
ENJOY "stutter-free" Diablo 3 !!!!!!!!!!!!!!!!!!!
