Help with graphics settings?

[jirachiband]

So I was hoping someone could tell me what my settings should be to get "perfect" graphics. By perfect I mean that they aren't being altered in some way. I'm trying to get a screenshot of something, but upon closer inspection, they look very different then what they should look like. I realized the window was maximized, so I changed it, but it's still not right... I looked at the explanation of what each setting does, but most of it didn;t make much sense to me. My settings:
No postprocessing shaders
Rendering resolution: Auto
Window size: 1x
Rendering mode: Buffered rendering (Non-buffered makes my screen black, so I couldn't see what that looked like)
Frameskipping: off
Texture filtering: auto
Texture scaling: off (xBRZ) Deposterize is unchecked
Hardware transform has a check
Vertex cache also has a check
Strech to display and small screen are unchecked
Vsync is unchecked
Mipmapping has a check
Hardware transform has a check
Lazy texture caching, retain changed textures, and low quality splines and Bezier curves are all unchecked
Anisotropic filtering is 16x
All hack settings are off

Thanks for any help!
