So you can say without a doubt that this actually has an effect?
…because everything I have heard states that multisampling AA is just not something we can have with deferred rendering, and so we’re left with ghastly post-processing substitutes like FXAA, and SMAA, and to a slightly lesser degree TAA.
Sorry about the rant that is about to ensue… or… well, I’m halfway into it I suppose…, but you stumbled inadvertently into a pet peeve of mine, which can be summed up in the sentence: “I hate aliasing with a passion, but I’ll take it any day over even just the slightest hint of blur”. :7
…and blurry edges and detailing is exactly one of those things that makes things look less substantial to me - indistinct, unsharp, ghostly, wavy.
Supersampling is good - it actually takes more ground truth into the averaged value of each pixel, for geometry and textures both, as well as the projection getting to play into how the world is sampled (in a way it does not when a texture has been pre-baked-down into a smaller mipmap), making it look “more right”, and smoother by that means.
…But cut-down versions, that saves work by only fixing select bits, which are deemed “most egregious”, or even just makes a few educated guesses? -Naa, not quite. :7
…and even with supersampling, there were dozens enough in an apparent minority I’m part of, that Valve could be persuaded, back at one point, to make an improved supersampling filtering algorithm optional, after they first pushed it out in a beta, and Elite Dangerous players in particular complained about suddenly blurry visuals (the option is in the developer section of the desktop settings window: “Advanced ss filtering” is enabled by default, for those who’ll take some softness to the imagery, if it reduces aliasing – the rest of us can untick it :7).
Now… “proper” MSAA should have no effect of textures, I am pretty sure, so that sounds odd - they shouldn’t smudge: Keeping textures antialiased is the job of mipmaps and texture filtering, and the realtime AA should only affect polygon edges, AFAIK…
Ooo-kay… Sorry about all that. Totally get you, if your eyes glazed over, there. :7
