Just purchased this game via the GOG sale and was looking around for a widescreen fix. This seems to be what I'm looking for:

But the download link is dead, by chance does anyone here have this widescreen patch on their hard-drive?

Hi!
I looked into this thing, too. The link to the patch i found was dead.
But here:
http://arparso.de/nexus/forum/index.php/topic,39.0.html

But the briefings are unfortunately not properly in size.

Thanks.

EDIT: Regarding the screen-tearing, have you tried using your video card settings to make an entry for Nexus and force Wait for Vertical Refresh, that might help.

I tried forcing Vsync through the ATI CCC to be always on regardless of application settings but it didn't seem to work. Maybe I should try to make a setting specific for Nexus...

I am also developing a mod that makes the game look better in widescreen and fixes some stretching that occurs when playing in widescreen. As well as improving the look of the background starfields drastically and other small HD improvements. Currently it is only for 16:9 resolutions such as 720, 1080p 2560x1440, etc. But I plan to release a 16:10 version as well.

I recommend anyone playing this game in widesceen downloads this mod. As it only seeks to improve the look of the game.

Unfortunately this doesn't fix the briefings but I am looking into how difficult that might be to fix.

You can find the mod on Moddb.com I can't paste a link but just search ModDB for "Nexus HD widescreen"

The title of the mod is "Nexus: Jupiter HD Widescreen 16:9 (1080)"

Nice

The registry tweaks at WSGF are easy to do and work perfectly at 1920x1080.

Or you could simply update your game. ;) Support for modern screen resolutions was added over a year ago.
