Perspective tweaks for The Witcher?

[khumak]

After seeing all the good reviews about The Witcher 3, I noticed The Witcher 1 and 2 on sale in Steam for about $1 each so I decided to try them.  At first it seemed like the type of game I like but it became very clear after about 20 minutes that I could never play it without some way to change the perspective. 

 

They literally make me nauseus after about 20 minutes of playing.  What's odd is that out of all the different RPGs and FPS games I've played over the years, this is the only series that makes me sick.  I think it's because turning is too fast because of the perspective but I couldn't find a way to change it.

 

I didn't bother buying The Witcher 3 because from the videos I've seen of it, the perspective looks the same as the first 2.
