nVidia Big Bang Driver (GeForce 180.48)
Direct3D (Legacy)
With slightly older Direct3D games utilizing 8xMSAA, there is a large performance gain in Serious Sam 2. I wasn’t expecting this so I was pleasantly surprised. The performance gain is substantial enough in actual gameplay that I can go from my previous setting of 16xCSAA to 8xMSAA when playing the game. There is also a slight performance gain in Call of Duty 2, while the other games were basically unchanged.
IMO, most of the results you found can be discarded as statiscally insignificant. Nvidia’s claims hold some truth, but only under very specific settings and/or resolutions. They brought more then just FPS gains though
True, but to be fair I only tested one game on nVidia’s list (Bioshock), and I observed a good performance gain there with 4xAA.
If you play the games on nVidia’s list, I have no doubt you could see some good performance gains.
