I feel it's more relevant to have it on the game page so people don't have to go hunting for the information. Because they may not even be aware or know they can do it with that specific game. That's why they go to the game page in the first place.
And unless they somehow end up on the page for my AA compatibility document for Nvidia GPUs (Not something I think you'd easily stumble upon really) or find the relevant thread on Guru3D. It'd be really easy to miss.
"Hackable" in my mind means being able to by means outside of the game itself. Because the majority of games either don't have any AA at all, or are not going to have any way at all to force it through some kind of config tweak. I'd certainly think that a driver level hack that needs compatibility flags set on a per profile basis that aren't exposed by the vendor's own program to be third party related. (Because the driver is intercepting and forcing things)
I respect your rules and will keep it in mind in the future. But it seems like a missed opportunity to keep information on a game by game basis easily visible.
Sorry for the trouble.
