Standard anti-aliasing enabled through the settings menu is FXAA-based, with some temporal processing. MSAA can be switched on by editing the file bin\config\base\rendering.ini in the game directory and setting AllowMSAA=true and MsaaLevel=2|4|8 but the consensus seems to be this doesn't improve things much, while the performance impact is significant. Another setting in the same file, UberSampling=1, could offer a bigger improvement but with an even larger performance hit. The most practical solution, given sufficiently powerful hardware, is probably to enable Dynamic Super Resolution (DSR) via the nVidia Control Panel. Witcher 3 graphics is quite amazing and can get even better with community-created mods. It might take some tweaking to get there but the result can be like this: https://www.youtube.com/watch?v=28lGfkdkJHI https://www.youtube.com/watch?v=28lGfkdkJHI
