MSAA is pretty old at this point and the reason it doesn’t work well anymore is also because there’s now a lot of details in games that doesn’t require more geometry and that’s a good thing. That’s why we now have AA that doesn’t rely on the actual geometry. TAA isn’t the only one though, my favorite is SMAA and FXAA is honestly not bad either (even though it seems to depend a lot on the implementation). Both of these don’t have ghosting and they detect edges that aren’t actual geometry.
