I've heard that this game has problems with stretching on widescreen resolutions and I'm wondering if the GOG version is any different. Any answers would be greatly appreciated.

I'm an idiot. Beyond Good and Evil is the game with the widescreen stretching problem, not Advent Rising; I got confused because they both force widescreen play. My actual question was supposed to be asking whether or not there was a way to remove the black bars on widescreen resolutions, but your post answered that anyway. Thanks very much.

Just a small addition to Ralackk's post. You need to edit these files
1. System\Mydefault.ini. You need to edit these lines:
FullscreenViewportY=1080
FullscreenViewportX=1920
2. System\default.ini. You need to find "[D3DDrv.D3DRenderDevice]" section and (re)place this line:
Widescreen=true

Setting widescreen to true will get rid of the black bars, but the game is stretched vertically, that is all persons are now super-thin.
Here's the trick to get the right proportions if your monitor has a 16:9 aspect ratio.
Edit the config file mydefault.ini in Advent Rising's system folder and find the following two lines:
FullscreenViewportY=xxx
FullscreenViewportX=xxx
Set the value of FullscreenViewportY to your maximum vertical resolution of your monitor, e.g. 1080.
Set the value of FullscreenViewportX not to your maximum horizontal resolution but to vertical resolution times 1.3333333, e.g. 1440.
(If your monitor has a 16:10 aspect ratio, eg. 1920 * 1200 it will still be a bit off.)
Now the picture gets stretched to it's correct proportions by your monitor. Sorta like with anamorphous DVDs.

I don't seem to have the mydefault.ini file

dont forger to put in the FOV command
F4=FOV90

Has anyone found the file on Windows 7?

I have found these setting work well on my Windows 7 x64 system.


D:\GOG\Advent Rising\System\Default.ini


[WinDrv.WindowsClient]

FullscreenViewportX=800
FullscreenViewportY=600

Change to:

FullscreenViewportX=1920
FullscreenViewportY=1080

[D3DDrv.D3DRenderDevice]

LevelOfAnisotropy=1

Widescreen=false

Change to:

LevelOfAnisotropy=4

Widescreen=true

Thanks Trebor

It works nicely even changing the values to 2560x1440. The menu remains stretched, but the rest of the game looks perfectly now. Thank you, Trevor.
