I wanted to have this discussion for a while... what are your favorite options for AA ?
Methods I know of :
Multi-Sampling -> Native Skyrim's AA. Decent result and glitch free at 8 (max). Not to expensive (roughly 1.3 FPS on my system). Incompatible with ENB.
Driver's AA -> Depend on each system, I actually never tested mine, always left it to application-controlled.
SMAA -> Good results, a bit above MSAA. However I sometime have slightly "bright" edges (they seem to "glow" very slightly). Tend to screw up the UI.
Downsampling -> require ENB for what I know to function properly. Not an AA method by itself, it simply improve the already in use technique. Huge performance impact.
EdgeAA -> Featured in enbseries. Give some ghosting for whatever reason when used alone.
Subpixel AA-> Featured in enbseries. Never did too much tests with this one.
Temporal AA -> Featured in enbseries. Used to have a lot of issues (especially ghosting on medium FPS). Got fixed in later versions of enbseries. Performance hit a bit bigger then the other technique for what I know, but give really nice results. Actually fix completely AA with coupled with Edge AA for me (but the overall cost is about 4 fps...)
I usually go with EdgaAA + Temporal AA when I just want very nice and clean visuals (usually on setups where I don't care at all for my FPS), or simple SMAA injection for regular playthrough (despite the few glitches I mentioned above, the general visual quality compared to the cost).
What do you guys use ?
I know that Kyo (author of K ENB) gave up on temporal AA because it didn't work properly on its hardware and recommand SMAA + downsampling. But I can't exactly use downsampling for playthrough on my poor laptop :P
