NVIDIA FXAAThe first version of FXAA, the pixel shader based anti-aliasing method I developed at NVIDIA, is out in the wild.Can see a screen shot comparison of FXAA on slide 48 of Johan Andersson's DirectX 11 Rendering in Battlefield 3 GDC presentation. There will also be a DX11 SDK sample released soon on the NVIDIA developer page. Game developers who want to check out a mixed DX9/DX11/OpenGL sample pack (includes source and white paper) can email me directly.
