SLI AA performance was measured using Morrowind (Direct3D) and Enemy Territory (OpenGL). Morrowind does not receive any performance increase from SLI, while Enemy Territory does.

Testing Morrowind consisted of a walkthrough through the town of Seyda Neen and is documented in this article.

Note that gamma correct antialiasing was disabled in this test as a bug in the 77.77 driver causes 4X AA to be used even though SLI 8X is enabled.

Enemy Territory Performance
