Cosmoteer Official Forum

As the previous posts mention, no mods mode is just a different way of launching Cosmoteer, it has nothing to do with your computer's performance. Depending on how you're launching the game there are different ways to fix this:

If you're launching from the start menu folder, click the version that just says Cosmoteer, not the version that says Cosmoteer (No Mods)

If you're launching with the start menu's search function, it's basically the same as above. Note that it'll start to remember which applications you use more and priorities those, so if you've been using search, no mods mode at this point is probably the first result you'll get when searching for just Cosmoteer. If you launch the normal version of Cosmoteer enough though, it'll switch to that instead

If you're launching from the taskbar, you probably pinned Cosmoteer to the taskbar while it was running in no mods mode, meaning every time you launch it from that icon it'll launch in no mods mode. The fastest solution is to unpin Cosmoteer, launch Cosmoteer without no mods mode, then pin it back.

If you're launching from a desktop shortcut, you'll need to edit the shortcut to fix it; go to your desktop folder in file explorer, right click on the shortcut, and select Properties. Under the Shortcuts tab of the window that pops up (which should already be selected), there's a Target option with a file path in it. Simply remove the --no-mods from the end, then click Ok.
