Has anyone had the problem where there seems to be lines going across people's faces?  Does anyone have a fix?

I thought I just had an eye problem, but yes. I occasionally see lines across other people's faces.

And sometimes jaggies too.

Oh wait you're talking about a PC game?

Here are some answers i've discovered just incase someone comes across this doing a google search or somethin.

The face glitch that causes lines to go across people's faces kinda looks like a shader issue.  Regardless, it occurs during cutscenes on computers with a resolution in a 16:10 aspect ratio.  For me, I was at a resolution of 1680 x 1050, so I switched to 1600 x 900 (a 16:9 aspect ratio).  Then, I changed my graphics settings so that there were black bars at the top and bottom of my screen.  Otherwise, the picture was stretched to fit my screen, causing weird results (kinda hard to describe what a stretched image looks like).  If you are looking for this option, I found it in my Nvidia settings under scaling.

Another thing that helps with graphics on this game is something called Nhancer.  This program apparently has many professional modifications for a lot of games for people running Geforce cards.  If you use this with The Witcher and you are using SLI, go to the SLI tab and turn off compatibility for Prince of Persia.  This solved an issue for me where lights would go through objects.

I hope this is usefull to somebody.
