There are those among us who like to stick with official drivers, and that's fine. But for those of us who like to get every bit of performance (no pun intended) out of our GPUs, we know that beta drivers are a good place to start. NVIDIA has recently launched their GeForce 304.79 beta drivers, which adds a few new SLI profiles, some bug fixes, and NVIDIA's TXAA anti-aliasing.
Some of the major bug fixes follow:
The new TXAA anti-aliasing is only available for 600-series Kepler cards. If you don't know what it is, it's basically an anti-aliasing filter designed similarly to how animation film studios do anti-aliasing, and it produces a better picture but with better performance than traditional anti-aliasing. If you want to read more about it, head on over to NVIDIA's TXAA page.
