Ups, I've forgotten to send my desktop resolution:

1280x1024x24

SOURCE/help> ./chromeface
unknown chip id, assuming full r200 support
disabling TCL support
glResizeWnd: 800 600
r200UpdateSpecular before COMPSEL: 1
r200UpdateSpecular COMPSEL: 101
glResizeWnd: 800 600
glResizeWnd: 1272 949
glResizeWnd: 800 600

Same (100-101 fps) with "fullsize" window (1280x(1024 - KDE-Panel) ;-)
