It also catches edges inside textures which MSAA misses. This is the default in many modern games because it has very little overhead, though it tends to miss a lot of jaggies. As Nicholas Vining explains: "Morphological anti-aliasing looks at the morphology read: the patterns of the jaggies on the edges; for each set of jaggies, it computes a way of removing the aliasing which is pleasing to the eye. It does this by breaking down edges and jaggies into little sets of morphological operators, like Tetris blocks, and then uses a special type of blending for each Tetris block.
You can apply it with SweetFX , and many modern games natively support this. TAA compares the previous frame with the current frame to look for edges and help remove jaggies. This is done through a variety of filters and can help reduce the 'crawling' motion on edges, which looks a bit like marching ants. It cannot, however, remove actual ants from inside your display.
You should probably just throw that display out. As Vining again explains: "The notion here is that we expect frames to look a lot like each other from frame to frame; the user doesn't move that much.
Therefore, where things haven't moved that much, we can get extra data from the previous frame and use this to augment the information we have available to anti-alias with.
According to Nvidia, "DLSS leverages a deep neural network to extract multidimensional features of the rendered scene and intelligently combine details from multiple frames to construct a high-quality final image. DLSS uses fewer input samples than traditional techniques such as TAA, while avoiding the algorithmic difficulties such techniques face with transparency and other complex scene elements. In other words, it's better and more efficient at doing the things Temporal AA does, or at least it's supposed to look better once it has been properly trained for a specific game.
When it's not properly trained, it can cause a lot of blurriness. Anti-aliasing settings almost always include a series of values: 2x, 4x, 8x, and so on. The numbers refer to the number of color samples being taken, and in general, the higher the number, the more accurate and computationally expensive the anti-aliasing will be. Then there's the special case of the 'Q.
FXAA is among the best options, though there is a small cost for those clean edges. Nor line edges. Over one or two milliseconds, the program runs through pixels and picks out those nasty edges. To fix the jagged look, FXAA artificially develops an edge that produces a smoother finish.
FXAA is full of perks, but its most impressive one is that it runs its algorithm over every inch of the visible screen. Everything the player can see falls under the scrutiny of FXAA, even those elements otherwise ignored by older anti-aliasing tools. FXAA is also incredibly fast.
Early versions of the algorithm were able to work twice as fast as 4x MSAA. Today, FXAA is clocked in at 1. Enabling FXAA will work wonders for your visual experience without forcing you to take a big hit on the frames per second. There is no such thing as perfection, especially in the world of technology. When you activate FXAA, you may notice that some edges and textures will look a little blurry.
