Thanks to Mr a for the info .... After a long wait due to testing and code optimizations the new Amigamerlin v3.0 Final Driver has been Released, for 3dfx Voodoo4/5 configuration with Windows 2000/XP. Driver is shipped in two version, lite and full: the first does not include control panel (3dfx Tools) while the second is the complete package. Please note that lite versione requires manual 3dfx tools add-on after archive unzipping on hard disk. Clicking on Download button at the bottom of a page you may also read Release note while on line help for both driver setup and setting is available in Amigamerlin 3.0 XP installing procedure and Amigamerlin 3.0 XP Best Settings sections of this site respectively.
