I am using the latest version of ARToolkit (2.7). All of the example programs run perfectly for a short period of time, then the frame rate drops to around 1fps. I have noticed that it's not just the image that slows, if I attempt to move the window it goes as slowly. After a random period of time (around 1 - 5 minutes) it will go back to running properly (until it slows down again).
I am running WinXP on an AMD XP 1800, with a Logitech QuickCam Messenger and MS Visual C++ version 6 Service Pack 6. My normal video capture software works perfectly, the bug is isolated to the ARToolkit application.
Previously I used an older version (2.65), and I never had this problem. I suspect it has something to do with the drivers.
Does anyone have a fix for this, or any advice would also be welcome.
Thank you.
