Updating your OpenGL drivers for iScreensaver

Quick Links: Mac OS X | Windows XP | Windows Vista | Windows 7 | Windows (Advanced)


iScreensaver makes use of hardware-accelerated video cards for fast, high quality motion animations. For these features to work properly, the computer's OpenGL drivers must both be current and meet specifications.

For Mac OS X, this is generally not an issue, as the drivers are updated automatically. However, on Windows PCs (running XP, Vista or Windows 7) there are two issues: First, the generic drivers that ship with Microsoft OS updates are buggy and slow. Second, there is no automatic way to update the drivers.

Does your computer meet the minimum requirements?

Before starting, make sure your computer meets iScreensaver's minimum requirements: System Requirements.

Question: "why is this so complicated...?"

Sadly, outdated and buggy OpenGL drivers on Windows PCs are an altogether common industry-wide problem. There is no easy way to generically update these machines, but we hand out as much information and knowledge as we can to solve the issue.

Here is an example of another software vendor (no relation or endorsement implied) that have exactly the same issues:

Best of luck... but it's really not as difficult as it seems.
