Alfonso,
The #9GXE64Pro is supported by the latest VIB105.ZIP, here in the libraries.
Your flicker might possibly be from using the default refresh rate the card is
set for. To set the refresh rate higher, (you need to know what your monitor is
capable of; 70hz – 72hz is a safe bet), copy to the hard drive the utility
called 64REFRSH.EXE from the Power Pac disk that should have come with the GXE.
Run this, which will let you set your refresh rate, and automatically put the
command in your autoexec.bat.
Get in touch if you have any problems; I'm using this card very successfully.
John
