I’m having fun watching #EVO2018 and of course it has me inspired to get back into playing Tekken. When I tried to launch the game, I was greeted by a black screen with the startup video audio playing in the background. Alt-tab didn’t work, clicking on the task bar didn’t work. Well, crap!
Fortunately, internet to the rescue. This forum post pointed me at a game settings configuration file: https://steamcommunity.com/app/389730/discussions/0/1291817837621663705/
Tweaking resolution and fullscreen settings in that file got it launching appropriately.
As a good citizen to future me, I created an Evernote to avoid me losing the information in the future.
