I use OpenGL
In your system folder in your UT2004 main directory or where you installed it, there's a file there called UT2004.ini
to change to OpenGL open the file in say Notepad++ and on line 21 or
[Engine.Engine]
RenderDevice=OpenGLDrv.OpenGLRenderDevice
;RenderDevice=D3D9Drv.D3D9RenderDevice
;RenderDevice=Engine.NullRenderDevice
;RenderDevice=OpenGLDrv.OpenGLRenderDevice
;RenderDevice=PixoDrv.PixoRenderDevice
Change it from D3D9 to OpenGL as above
For Resolution look under
[WinDrv.WindowsClient]
WindowedViewportX=768
WindowedViewportY=1024
FullscreenViewportX=1920
FullscreenViewportY=1080
MenuViewportX=1920
MenuViewportY=1080
Windowed is if you play in a window
Full Screen is Full-screen gaming
MenuView is the main menu since you could play ut2004 in a really low resolution so the main menu and game resolution are separate
I set them to 1920*1080
for FOV at a resolution, I set it to 106.26 deg
you can do that in-game in the console just hit the ~ tilde key and type /fov 106.26
I used "Unreal Tournament 2004 CD Key Changer 1.0" to change my key and make it active which I got legit from buying UT2004 on GOG, or you can edit the registry but only on windows, as for Mac/Linux I do not know.
There was a 64 bit version of UT2004 but it was buggy as heck and didn't allow for the updated versions on gog since it was never ported over when midway released their pack with epic
