Just wanted to give a quick update to those who may be holding off because they read about performance issues...
First of all my rig; i7-3930k, at 4.6ghz, SLi 2x 680s, 16gig ram (4x sticks), Asus 144hz monitor
I've got everything on high, removed vsynch (always do this since this is an LED monitor), view distance at 100%, all effects on except that stupid movie grain (edited the file). And it runs EXTREMELY SMOOTH!
The game actually feels like its been out for awhile with how smooth it runs on my rig. I'm very impressed, they did their homework and made this a great buy. Lighting is incredible, and shadows are amazing; usually shadows suck the life out of a gaming engine...for some reason in Dying Light, this doesn't seem to be the case.
Grab the game if you can afford it... some people may have had performance issues, but I have to say it seems that I haven't had any! --Alright, back to killing zombies and trying to find a darn pistola!
