N7OR,

Please send me this file: c:\Program Files\SVKSystems\clearview\log.txt and I will try to see what is happening.
The fact that your computer works with FMS is not representative if is will work with ClearView or any other simulator. I wish the life would be that simple, but it is not. FMS does not support photorealistic fields (no need for much video memory) and uses DirectX.Todays simulators (including CV) have some minimal requirements for the video card and the video memory. In ClearView case, dedicated 3d video card with OpenGL 1.3 driver and 128 MB video card memory is required. Regarding you having 99% CPU utilization, the simulator needs to maximise the frame rate and uses a lot CPU for that. If we get it working on your computer, there is a way to lower the frame rate and get lower CPU utilization if that is what you want.
