Benchmark Results: High Quality 4x AA
Now we’ll see how performance plays out with 4x anti-aliasing enabled:
This feature really separates high-end cards from more mainstream boards, with the Radeon HD 6670 and GeForce GT 240 GDDR5 barely able to handle 1680x1050. At 1920x1080, the Radeon HD 5770 and GeForce GTX 550 Ti are the cheapest cards are able to cope and provide a minimum of 25 FPS.
CrossFire appears to be working, with the results from two cards notably higher than a single Radeon HD 6850 (though even a single card provides smooth performance at this maximum setting). SLI appears to have a problem at 1680x1050 with 4x AA enabled, but it works fine at 1080p and 1280x1024.
