Anyone with problems with ATI drivers read this.

If you think of it as a decimal, yes, it is same number. But when describing ATI's driver versions, that is a big nono and can cause big problems. Think of the decimal as a simple separator for two whole numbers. The first number signifies the YEAR and the second number signifies the MONTH. The 9.10 drivers were released in OCT 2009 and the 9.1 drivers were released in January 2009, ten months before the 9.10 drivers.

Hope this helps you understand the ATI driver numbers now.
