VXGI and HairWorks are techs primarily targeting the most recent architectures, both will run on NV or AMD, and both should run on Kepler cards if the settings are tuned back a bit. WaveWorks, Turbulence and FleX are implemented in CUDA, but will run on Kepler cards as well as . I think HBAO+ runs across all NV-Kepler/ as well as AMD, I’ll have to verify that.
