Why the fuck is steam overlay not working?
Can you give us any more details about what is wrong?
Try restarting steam and see if the problem is still there.
Restarting steam didn’t help out
i dunno what else details there are other that it doesnt fucking work
Make sure that it’s not being blocked by your firewall.
I just checked and it is allowed in my firewall.
Is the problem only occurring in Garry’s Mod, or all Steam games?
I just noticed that it doesn’t work in any game at all.
Try CTRL+ALT+DELETE and see if there’s a gameoverlay process going on, if there is make sure to terminate it.
It doesn’t run, not even when I launch a game.
Your best bet is to reinstall Steam.
