I have an application using Glut which is working fine on Windows 98. I tried running the app on a Windows NT box. If I’m logged in as a regular user, it is slower than hell (<1 fps). If I’m administrator, I get performance just like my Win 98 machine (>30 fps).
After reading some other post, I’m wondering if the app is going into software rendering mode for some reason. Is there any way you can find out if you’re using hardware acceleration or software acceleration within an app?
