Just purchased Aerofly Professional Delux but am unable to get the FPS above 30FPS for 3D scenery and around 55FPS for photo scenery.
Aerofly info:version 1.11.7.1, serial# 9A5260D5
System info:Windows XP-Home, CPU - Intel Pentium 4 @ 3.4GHZ, memory 1MB
video: ATI Radeon X300/X550/X1050 with latest drivers downloaded from ATI

Stopped Antivirus and any other unnecessary processes such as QuickTime, MSOffice Quick launch, etc.

I suspect my video-card as the processor is never busy above 60% tops.
Any advice would be appreciated!!
Thanks, Jos.
