Sonic Adventure DX (2011) is a cartoon third-person platforming game developed by Sonic Team and published by Sega, and was released for PC on March 4, 2011. It is the updated version of the original Sonic Adventure DX from 2004.

This re-release of Sonic Adventure DX originally served to address some of the issues of the previous 2004 PC port, however, it also introduced new problems of its own, such as limited screen resolutions options, the game screen is pillarboxed to a 4:3 aspect-ratio, and poor frame skipping. Its configuration launcher also has issues of not saving the game's settings, and it is missing some of the unlockable Game Gear games from the previous PC port and GameCube version.

This version of the game was later replaced with another version in 2014 to address the issues with this re-release.

Essential improvements

SADX Mod Installer

A mod/patching tool that offers bleeding-edge mod updates, downgrading the later PC re-releases to the 2004 port, advanced and beginner-friendly options for installing mods, multiple mod presets (Dreamcast, Enhanced SADX, Minimal), downloads and install necessary dependencies, apply compatibility fixes, and configure SADX Mod Loader's settings before installation.
Includes a custom configuration tool to tweak various game settings, as well as remap controller and keyboard bindings for the Input Mod.

Anti-aliasing (AA)

Use Nvidia Profile Inspector (Nvidia only)[2]
  1. Create an application profile.
  2. Add Sonic Adventure DX.exe to the profile you just created; for the Dreamcast Collection version, also add Sonic.exe.
  3. Change the value of Antialiasing compatibility to 0x000000C1.
