Using dual 670s. Pegged at 60fps using VSync (I get coiling when playing PS2 without having Vsync on). Lowest I've gotten was about 48fps.
In the Nvidia CP my settings are:
AO: Not Supported
Anisotropic Filter: Application Controlled
Antialiasing-FXAA: On (ATI equivalent is Morphological Filtering in Fullscreen)
Antialiasing-Setting: 4x (FXAA/Morph Filter should be enough if you're losing framerate do to having AA on)
...everything else is Application Controlled or default.
In Game the following settings:
Video
Full-Screen Mode: Checked
Resolution: 1920x1080
Render Quality: High Quality
Texture Quality: Ultra High
Anisotropy: 4x
Atmospheric Distortion: 0%
Far Clipping Plane: 8192 (I noticed less hitching at 5000. It seems it wants to load stuff more frequently at anything above 5000)
Volumetric Clouds: Checked
Grass: 100%
Tree Detail: 100%
Bloom: Checked
HDR: Checked
Tone Mapping: Checked
Performance
Hardware Occlusion: OFF (this is not Ambient Occlusion. It's some wierd buggy thing)
Vertical Sync: Checked (Normally I recomend this to be OFF, but with some of the newer cards like the 7900 series or 600 series you may want it on to prevent that nasty coiling sound at times. Since I don't have a 120mhz monitor not like I'll take advantage of higher frames anyhow.
Triple Buffering: Checked
Character Occlusion: Checked
Use Provided Shaders: Checked (I didn't notice any difference with this on or off)
Animation LOD: 80%
Environment Particle Density: 10%
Player Spell Particle Density: 50%
Target " " " : 20%
PC " " ": 10%
NPC " " ":10%
(Particles are the #1 killer of frame rates during large raids/groups etc).
PC:
Win 7 Home Premium
i7 3770 3.4 OCed to 4.1
16GB DDR3 RAM
2GB MSI 670 OC PE. x2 (although only 2GB of Ram is used).
