Improving the wiki page concerning Anti-Aliasing


Recommended Posts

That's exactly why we separate AA into pre processing and post processing methods

You can use postprocess-AA AND not have blurred/affected UI elements. As Expack3 above pointed out you can do that with GeDoSaTo in some games because you can select in which 'pass' the AA is applied, thereby completely ignoring the HUD elements. It all depends on the way the rendering pipeline is set for a game I suppose.

Supersampling (SSAA, or OGSSAA if you like the nvidia name) and downsampling are not exactly the same thing: merging what I could find here and here we could say the first is an actual AA method, transparent to the game where every pixel is sampled more than once before being displayed. But the game is not actually aware of the thing

 

The later instead technically fake your resolution and the game will actually have to recognize the new one (thus games that don't support 4k resolution wouldn't possibly work with 4x 1080p downsampling)

The results should be the same eventually

 

Besides, I believe this could be the bible of AA

Other goodies are some old GeDoSaTo ance stors and a nice coverage of ATi box, narrow, wide, edge detect methods (which I have always been accustomed to see in the CCC)

 

Aand.. do you know if all these methods work even on pre-unified-shader cards? Because I gather that custom AA methods were just an innovation of DX 10 times

 

Last but not least: is AMD and NVIDIA still producing different looking images?? This is pretty lame imo, and would make every benchmark pointless

      Instructions
      Install the game.
      Run my patch.
      Select if you'd like to play with AA.
      Select your desired resolution.
      Play.
       
      What it does
      - Copies the fixed exe over the original
      - Runs the resolution patcher
      - Applies an affinity (& 640x480 mode) fix, this can be uninstalled from "Program and Features" ("Add/Remove Programs" in XP) later, it's called "Silent Hill 2 Processor Affinity Fix", for example after you uninstall the game you may want to uninstall this too.
      - Auto sets the game to 640x480 (which is actually the resolution you have selected eg 1920x1080) and graphics settings turned to the maximum (minus the noise filter)
      - Applies my AA fix in case you want to play with AA. If you don't plan to, no reason to enable it, as the hack causes a few glitches (still 90% of the game looks fine, and really.. AA is a must with this game..)
