GUI questions

Miscellaneous Forums/Blitz Showcase/GUI questions

I'd like to get some input on the minimalist GUI, I am currently using...

3D:

2D:

A number of windows which can be moved, minimized to tray, resized and closed... You can choose 6 different resolutions, but right now only 800x600 and upwards are really useful.

It's basic 2D on 3D, so I am interested in what kind of problems you are having.

What kind of FPS do you get?
Are there any display problems?
Is it too minimal or should I use solid title and buttons(more Windows like)?

EDIT: Which graphicscard do you use?

EDIT\2: This thread was originally posted in 'game design', but noone replied, so I am trying my luck here.
