I don't want to rush to conclusions, but so far, it looks like probably the best thing since Looking Glass walked the earth.
I was also that enthusiastic about the game at first, but after some time I found it a little dry and repetitive. It is still a nice game nevertheless, but as far as enjoyment is concerned, it doesn't keep up with Deus Ex or Thief on the long run, in my oppinion.
I found some nice tweaks in the official forum to get a nicer visual appereance:
Open: X:\Users\USERNAME\Documents\My Games\Dishonored\DishonoredGame\Config\DishonoredEngine.ini
Search for [SystemSettings] and set the following values:
MaxMultisamples=2 //Anti-Ailiasing mode 2,4,8, depending on your graphics card
Hmn, I had also played around with these settings, but couldn't detect a major difference. I suppose you'll have to enable AO in the driver as well or this cvar is simply obsolete. Have to try DetailMode later though. I thought I had it already maxed out...
One thing I wanna ask again: I've read a hint, that you can move faster when you havent equipped a weapon. But with which key can I put them away?
Hold down the f key. It is even possible to only have one hand equipped. I can't reproduce that reliably however. Sometimes when I holstered my weapons and I press right mouse key, I only have e.g. blink equipped.
