BioShock

Notes

It’s important to note that the Radeon cards in BioShock are running with 0xAA/16xAF, all the other cards (including the GeForce 7900 GT) are running with 4xAA/16xAF. AMD Radeon cards do not support AA by default in BioShock. AA must be forced by renaming the executable from “bioshock.exe” to “Oblivion.exe”. Doing this however disables all performance optimizations.

We have a strong suspicion that NVIDIA’s ForceWare 163.69 delivers a nice performance boost over the 163.67 driver. This applies to both Windows XP and WinVista. It looks like the performance boost is a little greater under XP though based on our tests: the GeForce 8800 GTX ran up to 8% faster under XP than Vista.

The rest of the cards perform pretty similarly regardless of OS used.
