Media editing and encoding, 3D modeling and rendering
The next few tests span the more heavy duty, enterprise front of WorldBench. These probably aren't apps your average home user is going to run everyday, but they give us a glimpse of how fancier, more processor-bound tasks fare with Service Pack 1 installed.

Photoshop image editing

Roxio VideoWave movie editing

Windows Media Encoder video encoding

3ds max DirectX visualization

3ds max 3D rendering

In media editing, encoding, and rendering tasks, Service Pack 1 performance is even closer to that of the release version of Vista. The largest difference is in 3ds max 3D rendering, with a 9-second gap between Vista SP1 and RTM. However, that only amounts to a ~1% change in total rendering time.
