I have not had any luck enabling widescreen support in Quake 2 and was wondering what I was missing.

I first tried the KMQuake2 mod, which was supposed to contain bug fixes, updated graphics, and widescreen support. IN game menus had only odd choices like 1920x1440 and such plus standard ones, but no widescreen resolutions. I tried editing the kmconfig.cfg (or whatever it was called) with a custom resolution too, but that didn't help. Then it turned out the game wouldn't start a game with KMQuake installed (would just dump me to menu after intro cutscene) so I uninstalled Q2 completely and reinstalled.

Next I tried the Unofficial Patch stickied in this forum. No widescreen from menu, and when I edit config.cfg and put the gl_mode to -1 as the instructions say, the game will only run in windowed mode.

Not related to the above, but the music volume slider also wasn't working, the music stays at max volume.

What am I missing?

I'm using a source port called Berserker that works fine with widescreen.

However, KMQuake2 also worked fine for me.

I guess give Berserker a shot.

Or use Unofficel v3.24 patch

Or Yamagi Quake 2. I need a custom resolution, too.

The necessary variables are:
gl_customheight "900"
gl_customwidth "1600"
gl_mode "-1"

I'm using "Ultimate quake 2 patch" which has kmquake2

made myself an Autoexec.cfg (renamed a standard .txt file & put it in baseq2 folder) with these lines

set r_mode "-1"
set r_customwidth "1600"
set r_customheight "900"
set cl_widescreen_fov "0"
set fov "90"

videos are pillarboxxed but gameplay is as it should be

Thanks for replies. I might try Berserker (I didn't try it initially as I'd read somewhere it didn't support the expacs).

I did find that with the Unofficial patch, it will show widescreen modes if I set the renderer to 3dfx; but other renderers do not show widescreen modes. If I use 3dfx though the game crashes with a message about it couldn't load some 3dfx library.

For now I have found a resolution that is at least wide enough that I don't get headachy so even if not widescreen, the game is now playable so I'll probably just run with it as is.
