Here I post some of the informations I have collected over time, which a new player may find useful.

Playing in HD Resolutions
Similar to Elite Force, the game doesn’t support resolutions like 1080p in the menu, but you have this time to options. The best way is to use the coop mod, which also brings you widescreen support in the main menu. Alternative you can set it manually. For that you go to your install folder and into BaseEF there you open with the Notepad for the [username].cfg and add the following lines to your desktop resolution:
seta r_mode "-1"
seta r_customwidth "1920"
seta r_customheight "1080"
seta r_customaspect "1"

How to play online
Like with many other Games from this era, the Master Server are long gone. So, you will not be able to see the server list. You can fix this by download the Master Server Patch: https://www.moddb.com/mods/hazard-modding/downloads/master-server-patch-for-star-trek-elite-force-2

Improve game performance
By renaming the ef2.exe to quake3.exe you will resolve a number of issues and have a massively impact on the gaming performance

Is there any chance to play the game with other Language Packs? I have the original German Version here but it does not work well and needs a disc. Any Insight on that?

Was hast du denn für Probleme? Ich habe EliteForce 2 kürzlich erst unter Win10 von der Original-CD installiert, kurz Google genutzt um einen alternativen Weg zu finden, die "EF2.exe" startfähig zu bekommen und dann lief alles. Wie du die aktuelle Auflösung einstellst, steht ja im ersten Post.

Hello Skeldel, as Windemir wrote, the CD version should work on Windows 10 without a problem. Should you prefer a face to face talk, you can also write me directly via Discord or talk with the master of Elite Force 2, Chrissstrahl. He is not only the creator of the Coop mod and knows "everything" about the game, but also speaks german ;)

It did work, but I don’t have a Disc Drive anymore and I would like a digital solution

Hello Skeldel, take a look at schote.biz. There you can find a patch to switch the game into a german version.

Thank you!! very helpful

I've found that the HUD is extremely small when playing at 1920x1080. Is there a way to scale up the HUD?

Sadly, there isn't any way to upscale the UI in the config. I didn't play the original Elite Force 2 for a long time. So, I don't know how small it really is. You can try the coop mod, maybe the UI is a bit bigger in it.

Edit: Sorry, I just saw that Chris already answered it in your other post.

This should work just fine: https://www.nexusmods.com/startrekeliteforceII/mods/438

I uuuuuuhhhh, accidentally set the game to 16 by 12 and my game can't launch. I didn't track what my username was so what do I do?

The cfg that was modified most recently should be yours.

those curious...running the game in DX12 will likely solve all your issues with the game...including compatibility. I refer you to this url: https://www.gog.com/forum/star_trek_elite_force_ii/star_trek_elite_force_ii_in_dx12solve_all_your_graphical_issues_here

So, a lot of issues can be mitigated by editing the cfg file in the base directory. This is a Q3 engine game, so a lot of tweaks that affect other Q3 engine games also apply here.

For some reason, the game downloads with a bunch of random cfg files. I'm pretty sure that that is a QC issue on the part of GOG, those files aren't used. So, my advice is to delete all of the random cfg files, and then start the game once so that it creates a cfg for you.

FPS - it's tempting to set this higher, but if you do, it affects the way gravity works in the game. In EF1 is actually makes it impossible to complete the game, I'm not sure about EF2. STUTTERING - Initially I found that the game reported a good fps, but it was stuttering terribly. I tried a bunch of different suggestions (rename exe, etc), but eventually found via PCGamingWiki that this setting actually fixes it. The explanation I have found:

* -1 = skips drawing results in black screen
* 0 = uses glDrawElements if compiled vertex arrays are present, or strips of glArrayElement if not present
* 1 = forces strips
* 2 = forces drawElements
* 3 = path for non-vertex array testing

Indicates that this controls the way primitives are rendered in some way. Using the "2" setting eliminated the stuttering.
