What exactly didn't work with Wine 1.7?
Did Steam fail to launch? Did Borderlands fail to launch?
Also, the Debug you posted only shows the Futuremark output. I would like to see the Steam and Borderlands too.
From the Debug it looks like Wine isn't using OpenGL properly.
This is either an Nvidia driver problem or maybe you can just set Direct Draw Rendering to "opengl" in PlayOnLinux Display under configure:
- Launch PlayOnLinux
- Click Configure
- Select virtual drive
- Click Display Tab
- Direct Draw Renderer: opengl
Also I found that Steam will work with most Wine versions if you add -no-dwrite to the argument in configure... like this:
Otherwise, the side-effect is missing fonts.
