Unbearable aliasing on GTA IV

[Determined]

I don't know why, but my game is so fucking aliased it's painful to look at. I'm running on 1920x1080 on a 25 inch monitor, I've got all my in-game settings maxed out, vsync on & my graphics card is set to 32x CSAA (Enchance Application setting) with auto Gamma Correction enabled. As far as I know, there's no way to adjust the AA in-game so I have no idea what to do to fix this (if it's at all possible).

Here's how the game looks:

Play with definition off. I personally think it makes the game look a lot better. That's all I have to say, sorry.

GTA IV doesn't support traditional anti-aliasing. So using AA in your driver wont make a difference (and man, 32x is way too high for any modern game, go with 4x max). However, you can inject 'FXAA' into the game (Fast Approximate Anti-Aliasing). It's basically the same thing, but with much better performance and slightly less quality.

Click HERE to download FXAA. Since GTA IV runs using DX9, copy the contents of the 'd3d9' folder into the same folder as your GTA IV exe. Tada, FXAA applied. Keep definition on
