Yeah, refer to this thread: http://steamcommunity.com/groups/SpecialK_Mods/discussions/0/1319962514590954694/

I just released this version today.

Is this done through specialK? Is it available for download?

There's generally no problem here. I manage window activation and deactivation for the game, since I operate under the assumption that the Unity engine can't deal with D3D9 device resets. It's not a feature of the engine, so it's never tested :P

Plus Setsuna is bad for judder as you well know lol. Ori and the Blind forest doesn't framepace well in some places unless its forced into dx9 mode for me.

You found a way to do that without them crashing on exit? Yooka laylee uses a fullscreen hack but crashes on exit unless its in borderless mode.
