"better performance will be.\n\nIf unsure, select Native.");

"Reduces the amount of aliasing caused by rasterizing 3D graphics, resulting "
"in smoother edges on objects. Increases GPU load and sometimes causes graphical "
"issues.\n\nSSAA is significantly more demanding than MSAA, but provides top quality "

"effects, and textures.\n\nIf unsure, select None.");

"Calculates lighting of 3D objects per-pixel rather than per-vertex, smoothing out the "
"appearance of lit polygons and making individual triangles less noticeable.\nRarely causes "
"slowdowns or graphical issues.\n\nIf unsure, leave this unchecked.");

"Forces the game to output graphics for any aspect ratio. Use with \"Aspect Ratio\" set to "
"\"Force 16:9\" to force 4:3-only games to run at 16:9.\n\nRarely produces good results and "

"Selects the stereoscopic 3D mode. Stereoscopy allows a better feeling "
"of depth if the necessary hardware is present.\n\nSide-by-Side and Top-and-Bottom are "
"used by most 3D TVs.\nAnaglyph is used for Red-Cyan colored glasses.\nHDMI 3D is "
