Essential improvements[edit]

SADX Mod Installer[edit]

Allows to set resolution, frame rate settings, HUD scaling etc. before installation (in custom mode), and auto-detects desktop resolution.
Supports Steam, 2004, DC Collection/Remastered and can also be installed over BetterSADX.
Has multiple mod presets (Dreamcast, Enhanced SADX, Original), a guide mode for selecting individual mods to install, and a custom mode for full control
A list of additional recommended mods can be found here.
Replaces the game's executable with the version from the 2004 port of Sonic_Adventure_DX. Most of the new tweaks from the 2011 port are removed/rendered inaccessible for this reason.

Issues fixed[edit]

Low FPS[edit]

If the FPS is stuck in the 40s and won't rise to 60, disable the in-game FXAA and Vsync and instead, force them through the Nvidia/Radeon control panel.

Sky Chase too difficult[edit]

Reduce resolution to 640x480[2]

Notes

This might be caused by BetterSADX.[citation needed]
Setting an even lower resolution, such as 320x240, makes the level even easier, however this may have other unintended consequences, as the original Dreamcast version ran at 720x480 (in 4:3).

  1. 1.0 1.1 File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/71250/ in addition to or instead of this directory. The app ID (71250) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
