Hi All,
EEAH is set to a native resolution of 640*480, and crashes for me personally when I try to adjust that by using crtl F4 in game.
If you open a dos command box and put in:
C:\Program Files\GOG.com\Enemy Engaged - Apache vs Havoc\Aphavoc>aphavoc 3dw:1440 3dh:900 force_resolution
I can play the game at my native widescreen resolution of 1440*900. Just replace the 1440 and 900 by your own values and you should be good to go.

Well, It kinda works. I can up the res through the command line, but my cockpit appears in a box in the middle of the screen, taking up about a quarter of the screen area, like in old FPS's where you would increase the border size- except the rest of the graphics are still there outside the cockpit, working perfectly. I think it's because the game is trying to use a 640x480 cockpit texture rather than a larger one. Any ideas for a solution?

No, in EEAH the cockpits only exist in 640x480, even if you run higher resolutions.
EECH supports any resolution, so I would suggest using that instead.

Pardon my butting in, but I just bought & installed EECH, and it seems to be working fine at first try (I need to sort out the controls). But will I be able to run all the helos at 1366x768 if I also buy EEAH as well, or will I have to limit it to 640x480? I'm currently d/l the 1.12 patch if that helps...
EDIT: I found the 1.13 patch

The apache cockpit is limited to 640x480, even with eech the game either doesn't show the MFDs correctly at high res or it crashes (it doesn't crash on my machine but I've read of crashes on other peoples machines).

However eech + community patches and mods does have apache support (with an enhance 3d cockpit).

I own an original and gog version of eeah and I can't really recommend them on new machines, but eech is well worth buying (and then patching/modding).
