Essential improvements


Essential patcher which integrates the NewDark patch and fixes various issues.
Latest versions automatically disable the intro video for you (if you wish to re-enable it, add always_play_intro to the cam.cfg or cam_ext files).
SS2Tool requires Vista or later due to included Rsync, however NewDark runs on 2000/XP or later. One can patch it on a Vista machine then transfer it to an older machine. Digital versions already include NewDark and compatibility fixes for modern systems however the tool is still necessary for proper mod support.

Issues fixed

Random crashing

Use SS2Tool[citation needed]

See SS2Tool.

Jerky/Uneven mouse movement

Add a line to cam_ext.cfg

Install NewDark via SS2Tool.

  1. Go to the installation folder.
  2. Open cam_ext.cfg.
  3. Add the line use_raw_mouse_input.
  4. Save the file.

Left-clicking or dragging does not work

Use SS2Tool[citation needed]

See SS2Tool.

Small game window or black screen

Edit cam_ext.cfg to disable multisampling[citation needed]
  1. Go to the installation folder.
  2. Open cam_ext.cfg using Notepad.
  3. Comment out and change multisampletype 8 to ;multisampletype 8
Enable SS2Tool Safe Mode[citation needed]
  1. Download and run the SS2Tool installer.
  2. At the Choose Components installation step, enable Safe Mode.
  3. Click Install and finish installing.

UI too small on high screen resolutions

Edit cam_ext.cfg to enable ui scaling[citation needed]
  1. Open cam_ext.cfg in Notepad or any other text editor.
  2. Uncomment the line ;d3d_disp_scaled_2d_overlay 64 by removing the semicolon.


If this does not fix the issue, you may try scaling the UI to arbitrary resolutions by re-commenting out the above line (add back in the semicolon), uncommenting the line ;d3d_disp_scaled_2d_overlay 640 480 and adjusting the 640 and the 480 to your desired resolution. However, this may cause the ui to become blurry/pixelated, so try the initial fix first.

Poor performance on Mac wineskin version

Enable X11[8]

Find the System Shock and right-click on it. Click Show Contents and run In the Screen Options, you should see a checkbox that says Use Mac Driver instead of X11. Uncheck that box and that should fix the problem. If box is already unchecked then check it instead.

Can't dive in Mac or Linux version

Place this dml file in the SS2 folder[9]
