The guys from 3DChipset managed to find the latest Beta Detonator 29.80 drivers for WIndows 98, ME, 2000 and XP from the Gainward FTP which are dated May 24. There doesn't seem to be a great deal of changes except for multi-language and nView support as well as support for every nVidia based graphics card. There is no word on performance as yet.
