Hey everyone, thanks for all the useful information in this thread. I've got a kind of weird problem where when I run my game, it start with the overlay open and the store page open.
The game doesn't respond for like 15 seconds either. After that, I can interact with it and it works fine, as long as I use the --in-process-GPU fix.
The problem is, even if I don't use that fix the overlay comes up when I start the game. And using the fix, it's really annoying to have to close the overlay every-time and wait for it to respond again.
Has anyone else had this issue or found a solution? Thanks!
Edit: If I run from big picture mode it disables the api entirely but also the mouse in game. Interesting
