The pictures aren't very good, but hey... :-)
Here's the Sonnet running gearsppc.exe from the warp3d demo folder.
Here's a screenshot with my camera from a timedemo of 640x480
And here's 800x600. These are exactly the same results as the highest FPS on http://www.amigaspeed.de.vu/ indicating maybe there is a limit? 1024x768 sadly crashed.
Here a very bad picture of the test version of WipeOut. Couldn't get full screen... Something about not having the right modes.
