At the very least... change the fov to be around 80-90... It's default is far too low for computer monitors. But the rest is great too.. After fixing the damn mouse issues its FAR smoother and less stuttery (despite having a computer well beyond the power required for Ultra).....

One thing I am absolutely looooooving is turning off quest markers (bShowQuestMarkers=0).... BECAUSE unlike simply deactivating the quest in the game (which deactivates Clairvoyance as well)... This way the quest markers are gone except you can still use Clairvoyance (the spell that makes the blue line to your destination) if you get stuck.... Which is perfect gameplay - the way it SHOULD be implemented.

If anyone finds any other tweaks (there is a whole lot more to the ini files after all)

Post them here....

I can't underestimate how improved the game is after doing this..... I was infuriated with the mouse lag and the crazy slowed down Y vertical movement thing... This fixes it all.
