I can go up, but I can't go back down, at all. I tried appending

+set ui_console 1 +sv_cheats 1
and I tried
+set ui_console 1 +set_cheats 1

but neither will let me enable noclip to work around this.

I don't understand your question, and what you mean, a mission a map or what ?

How ever, if you have the GOG version:
+set cheats 1

+set_cheats 1 would never work set and cheats are two separate commands :)

///SPOILERS AHEAD\\\

I think I know what Weclock means, since I'm experiencing the same issue:

On the mission "Remove and Disable" (Enterprise hull), you have to disable three devices attached to the hull of the Enterprise. Since this is a low-gravity environment, you can jump very high in this area and you WILL NEED to jump in order to reach the three devices. However, in my game (and Weclock's), once you're in the air, there seems to be no way to go back down to the hull again. You just sorta float at the same height. It's like the game is supposed to apply gravity to you so you get back down after jumping, but it just doesn't.

Has anyone else experienced this issue? If it helps: I'm not using any mods, just a normal install of the GOG version of the game.

Here's a video of how the mission is supposed to work - now just imagine you can't actually go back down after jumping:

Thank you so much!

just as an fyi to anyone else who has this issue, the easiest way is to browse to your base folder and edit your *username.cfg* and add the line "seta com_maxfps 60"

Now it works exactly as designed.

I could make a script for that that changes the fps just for this mission and restores it at the end of the mission.
Put it in a pk3 and people could download and install it like the skip intro mod.

If you people thinks that is a good Idea.

Same thing here. No gravity.
How do u limit the fps? Where to go? What to do?
Tnx

The command is:
com_maxfps 75
or
com_maxfps 60

Is this a new bug with the GOG version?

No this is an old known bug in the game that only showed up as technology advanced. Anything over 80 FPS makes you fly forever see PCGW write up and fixes here: www.pcgamingwiki.com/wiki/Star_Trek:_Elite_Force_II#Fix_broken_low-gravity_areas

Did they fix this yet? If not everyone should message GOG about it.

There is some wrong information and a lot of missing information in that wiki.
Using some Quake/STV Elite Force commands will not do anything for ef2.

GOG cant do anything this is a known issue linked to FPS on modern systems, just cap the FPS. I tested it and it worked for me via driver control panel.

I woudn't say they that, but the question is how much effort that would be with Reverse Engineering and if it justified for the price of the game.

How ever, they could introduce a level script based fix, that would retain compaibility, have no negative side effect on anything else. Packed in a few Kilobyte small additional pk3, so it would be a tiny update. Created with a text editor and a simple archiver.

I would be willing to provide such a update or all the exact information (needless to that that would be absolutly free and no strings attached or credits needed).
I tried contacting them, but nothing happened. I just want to see the game work, I don't care for anything else really.
But they should be shipping it with the game, users should not have to find a workaround them self.

If they how ever build a fix into hardcode they should be checking for cvars if they feel fixing the physic is not viable.
sv_running 1 //client is also host
dedicated == 0 //issue does not occur on dedicated servers
