Did some research on these drivers & found that the FXAA setting is a shader-based AA that can do transparent AA as well (what MSxAA does--GPU-based AA for transparent objects) & can work either w/ MSxAA on or off.
So I turned FXAA on & turned MSxAA off to see if I could tell any difference. Have Adaptive V-Synch on as well.
Went up & flew awhile..............the graphics were beautiful....I couldn't detect any difference in graphical quality from 1 to the other but I could detect a VERY noticeable difference in performance.......even on this hoss of a box that I have running. Since all AA was being processed primarily by the CUDA cores & not the GPU the FPS literally locked on 60 FPS on this box regardless. This helped this 560Ti to handle more frames from the CPU & it showed.
Looks to me that Nvidia has finally developed a driver set that can really benefit us gamers, just as advertised.
