Quick post to document a problem I had and the solution that worked for me.
When streaming/recording Fallout 3 using OBS Studio, if I used Game Capture, OBS would show the game briefly but then freeze up, or worse, just show a black screen. Tried every setting in OBS that I could change for Game Capture, tried running OBS as administrator, even uninstalled and reinstalled OBS. Just could not get it to work. Didn’t want to use Fullscreen Capture for aesthetic reasons (it would capture my desktop, or notifications unrelated to the game, that kind of thing.)
So I broke down and read the documentation. Wouldn’t you know it, they had a solution to this.
I had to disable/close RivaTuner Statistics Server. That did the trick. Turns out having that overlay breaks Game Capture in OBS. I seriously would have never thought of that if I hadn’t gone in and found the OBS support docs.
Good documentation saves lives! Or at least prevents stress wrinkles.
