Well it seems like Nvidia has learned a lesson from recent discussions regarding the RX55 memory register `bug` contained in the latest 23.11 release and encountered on VIA Windows 2K/XP systems resulting in a performance loss as well as instant reboots and BSOD's. The 23.11 Detonator drivers have been removed as the official downloadable version. They have been reverted back to 21.83. On the other hand Nvidia is now offering Detonator XP 3D stereo drivers based on 23.11; released today. Check out the driver download pages for yourself and maybe grab the stereo drivers: Detonator download Win9x/ME Detonator download Win2K/XP Detonator download WinNT4
