Extract SweetFX files into the following directory = \SteamApps\common\Typing of the Dead Overkill\
Disable in-game Anti-Aliasing, it interferes with SweetFX
In order to run this game with proper rendering (locked to 1280x720)
you have to go to Steam "Launch Options" and copy/paste "disable-post-processing"
without the " "
Sadly it's forced to windowed mode... but at least it's rendering properly
and doesn't look like a complete crap.
