The Upgrade Advisor evaluates your system and recommends the version of Vista it would be best suited to run. It also inventories your hardware and the applications you have installed and lists any problems it sees with system issues, hardware devices, or incompatible software.
Many of the problems with applications seem to be related to problems with untested or uncertified device drivers, a problem Microsoft is working hard to address. Others are harder to explain -- on one test machine, Upgrade Advisor reported that Microsoft's own Microsoft Works application "may not work as expected after upgrading to Windows Vista." Still others may be the result of Vista's tighter security: the test machine's Java runtime and Norton Internet Security were flagged.
If you're not running XP, you can try the Vista Readiness Advisor on ATI's Web site. The ATI test doesn't inventory your apps like Upgrade Advisor, but it will give you more information on your graphics card -- and naturally, it makes recommendations aimed at selling you an ATI-based card.
The primary take-away from the ATI test is that to run Vista graphics well you need a graphics card with at least 256MB of memory. The reason is WDDM: if you try to run anything more demanding than the Windows Basic interface on a graphics card with less than 256MB of graphics memory, Vista will allocate 128MB of system memory for graphics, which may impact overall system performance.

Laptops have caught up with their desktop PC cousins in several categories over the past few years. CPUs, system memory, and even hard disks are as large and powerful on many laptops are they are on typical desktops. But the graphics on laptops still lag, and because they generally lack graphics horsepower, the graphics demands of Vista fall more heavily on them. |
