I tested specifically for it in Crysis 3 and Fallout 4 and could not tell a difference. I did see a small difference in Fallout 4, but I had to look for it way too hard for it to be worth the impact it had on performance. GTA V has 4 or 5 (maybe more) types of AA and I have 1 or 2 of them off or at the lowest (2x or FXAA). Those I have yet to notice either.
I stopped noticing the difference AA made back when i started to use 1440p, so I'm pretty pleased with how little I need it on 4K. I notice texture quality decreases much more than AA disabling/decreasing.
