Intel has decided to stop developing graphics drivers for Windows XP and Windows 2000 for a wide range of its i945G based chipset once the next version is out, so if you're expecting some new exciting features as per what Intel has done with the i965G series, then you'll be dissapointed.
The chipsets affected are as follows:
The current version of the drivers is 14.31.1 and the last version will be 14.32. Vista drivers will continue to be developed. The new version should be out sometime between now and the end of the year.
