If you want a NO COST modest performance upgrade for your GB3D (Laguna)
card, here's how to do it!

1st: WARNING

This process involves changing information in your system registry!  By
performaning this procedure you will be Clocking your video card BEYOND the
Board Manufacturers recommendations! - Do this at your own risk!

OK, now that's out of the way the stops involved are as follows:

1) From the START button select run and type in "REGEDIT"

2) Use the Search function and search for the word "LAGUNA"

    REGEDIT will find entry for CIRRUS LOGIC, with a sub-entry called
Laguna.
    Under Laguna is an entry for PERFORMANCE.

3) Performance will contain keys for:
    ClockSpeed (Default is 16, below the recommended max)
    Min             (Default is 16)
    Max            (Default is 18)
    Exotic         (Default is 0)

4) Change the Max setting to 20! (This allow tweaking of ClockSpeed

5) Change ClockSpeed to 18, or 19!
    Numbers above 19 created artifacts on my Hi-Res/Color Screens.
    **** DO NOT SET ABOVE 22! ****
    **** Blank Screen will Result, you'll need to BOOT SAFE to Change it
Back ****

6) Change Exotic to 1 (I think this helped)

Thats it
