NVIDIA FXAA Anti-Aliasing Linux Performance


A few months back the NVIDIA Linux driver introduced support for FXAA, a new anti-aliasing method. In this article are benchmarks of FXAA plus more information on this post-process shader-based anti-aliasing method.

FXAA isn't meant to replace MSAA (Multi-Sample Anti-Aliasing) or other AA methods but is rather something complementary. NVIDIA introduced this support to their 304.30 Linux graphics driver back in July while some games already provide support for using FXAA directly. NVIDIA has also brought FXAA to game consoles as this method of anti-aliasing is more lightweight compared to MSAA. NVIDIA offers the source-code to a reference FXAA implementation for those interested.

FXAA is short for Fast Approximate Anti-Aliasing. This was designed by Timothy Lottes of NVIDIA. Below is an email that Lottes sent to me that describes FXAA in much more detail.
