Doom 3 widescreen

To enable widscreen in Doom 3 you must have latest patch v1.3!
Go to Doom 3 directory eg. "Doom3\base", and create autoexec.cfg.

You must create/copy four config lines:

  • seta r_customHeight "XXXX"
  • seta r_customWidth "YYYY"

Change the XXXX and YYYY to set your resolution, and add third line:

  • seta r_mode "-1"

And the fourth line:

  • seta r_aspectRatio "ZZZZ"

If your screen aspect ratio is 16:9, change the "ZZZZ" to "1".
If your screen aspect ratio is 16:10 or 15:9, change the "ZZZZ" to "2".

Your autoexec.cfg should look something like this if you have 1680x1050 resolution:

r_mode "-1"
r_aspectratio "2"
r_customwidth "1680"
r_customheight "1050"

Available and tested resolutions:

1280 x 800 (16:10)
1440 x 900 (16:10)
1680 x 1050 (16:10)
1920 x 1200 (16:10)
2560 x 1600 (16:10)
1024 x 576 (16:9)
1280 x 720 (16:9)
