Settings not saved.

[bothered]

On restarting the game my video setting revert back to default, IE, I lose my resolution. And a manual save would be nice.

When you change the resolution and hit apply (doing its little menu restart), it doesn't save. Go back to the video settings a second time and set them again, then they will stick.

edit:

I think my previous solution is wrong, I managed to get it to save by applying the resolution settings, and then entering the game. I also walked through a "save point arch".

I think you also have to use borderless.

You need to modify GameUserSettings.ini in:
AppData/Local/Echo/Saved/Config/WindowsNoEditor

The configuration file paths for Linux/Steam Deck and Windows are documented here:
https://www.pcgamingwiki.com/wiki/Echo#cite_note-Proton_path_note-4

I tested it on the Steam Deck. The game's Steam ID is 551770 (if you're using a non-legal version or a non-Steam game, the ID will be different: https://gaming.stackexchange.com/questions/402316/steam-app-id-of-a-non-steam-game-added-to-steam-in-steamos-on-steam-deck)

It's a bit annoying, but doable. Since the game isn't officially supported on Linux, you'll have to dig a little deeper. The config file path is:
~/.steam/steam/steamapps/compatdata/551770/pfx/drive_c/users/steamuser/AppData/Local/Echo/Saved/Config/WindowsNoEditor

I tested it with Proton 9.0-4 and Proton Experimental.

Also, I'm not sure if it's a bug, but on Steam Deck (and probably Linux due to Proton), GameUserSettings.ini was empty. I copied it from my Windows installation, and it worked.

Another small issue: when launching the game, the settings appear as if they haven't been saved, even though they are changed in the in-game menu. Just clicking on Audio/Video (without modifying anything or even pressing "Apply Settings") and then closing the menu updates the config.

Do this before starting a game, or you'll need to go to Audio/Video settings mid-game and manually press "Apply Settings."

You should see something like this:

[/script/engine.gameusersettings]
