Diablo® III

**Nvidia GPU Users** Smooth Graphics Fix

This is how I fixed my stuttering graphics. I have a 580gtx btw...current driver 314.22

Nvidia control panel settings->

Ambient Occlusion - Off
Anistropic filtering - User's choice start low first
Antialiasing FXAA - Off
Antialiasing Gamma Correction - Global (On)
Antialiasing mode - Application Controlled
Antialiasing Setting - Application Controlled
Antialiasing Transparency - Off
CUDA - GPU - Global (All)
Maximum Pre-Rendered Frames - Use 3d Application Setting
Multi-Display/mixed-GPU Acceleration - Single Display Performance Mode
Power Management - Prefer Maximum Performance
Texture Filtering Anisotropic Sample Opti... - Off
Texture Filtering Negative LOD Bias - Clamp
Texture Filtering Quality - Quality
Texture Filtering Trilinear Optimization - On
Threaded Optimization - Auto
Triple Buffering - Off
Texture Filtering Anisotropic filter optimiz... - Off
Vertical Sync - Use 3d Application Setting

Now find your D3prefs.ini file in your User -> My Documents -> Diablo 3
Right click -> edit
Find HardwareClass "#" Change # to 1 and Save/Exit

If you are having crashing problems as well and you are using windows 7 or later.
Find your Diablo3.exe -> right click -> properties -> compatibility tab
Check Run this program in compatibility mode for: Select Windows 7 in drop-down Save/Exit

Whenever you run Diablo 3 instead of double clicking the icon right click and run as Administrator.

In game settings
In graphics tab uncheck every box EXCEPT V-Sync
Set all drop-down menu graphics options to lowest values. Increase as FPS allows.

Goodluck! Hope to see you in game.

glad it works for you.
personally i have my hardware class set to 6 with no problems and i run a 560ti. i did this on purpose btw. setting it to 1 you miss out on a lot of graphics features.

i can post my nvidia settings, prefs, and system summary if anyone wants to look at these to see what i have going on.

just helping others with stuttering graphics probs. just giving bare minimum specs. They can go from there. But, this is a good starting point. :)

I'de like to try this OP, but I seem to be blocked from opening "nvidia control panel", strange.

try reinstalling your graphics driver.
when you do make sure to go to "custom" and "clean install"
that way it removes all the previous stuff

use adaptive vsync instead and turn off in-game vsync

if you want an even sharper d3 override the anti-aliasing setting
I play at 32x AA with sli 580's
