(Mort's Game Tweaks) ini file changes et al for game performace?
When the official forums were up, there was a thread in the tech forums about some things you could do to help improve your game performance. Most of it was ini file changes, but there was other stuff, too.
Since the official forums have been removed, that thread is no longer accessible.
I don't suppose anyone has captured the contents of it, and posted it somewhere, or could post it here, have they?
