Well I've run the 88.44-whatevers. They work fine. They came with the card on the CD-ROM. Then I tried 91.xx-something, and they worked fine. Now I'm testing 93.71 (which are listed as WHQL certified) and I've got no problems except at 8xS FSAA, which makes clipboard dots into rectangles. Dropping down to 4x FSAA solves this.
