wine users - Jun 2011 - New To Wine Paths Not Found & Oblivion IV Question

I just switched to "Linux Mint KDE" and from what I have been reading,
some Linux users are having some promising results with Playing Oblivion IV.

So far I have the newest Wine installed and Oblivion with the
Oblivion_v1.2.0416English patch...

So a few problems!

Under the Applications Tab under Wine, there is a windows folder that says
"Brows C: Drive" When I click on it, its says "The path is not
found"

The path is for that folders shows /home/documents/.wine

But the .wine folders real path is  /home/.wine

Second problem

Oblivion is really Laggy to the point it will not play, it worked good enough on
Win-XP (same computer.)

Are there any setting I can adjust?

want to add

when I go to detect video setting (In the oblivion launcher) I get this message
> 
> Video hardware unrecognized. Video quality settings defualting to Medium
Quality.
