Hello,
I had a strange problem with FMS : the computer freeze completely as soon as the plane take off. After reading theses post, I suspected that the problem was related to graphic card.
I run Win 2000 with a RADEON 7500 and DirectX 9.0.
In order to work, it is needed to disable some of the hardware acceleration.
First test if the problem can be solved : remove all the hardware acceleration. The amount of hardware acceleration slidder can be flound in the "screen properties" (for french users: propriété d'affichage / résolution des problemes).
Then run FMS, if the PC freeze again, you will have to try something else, this solution is not for you.
If it works, just make a litlle flight to be sure that everything is working.
Now close, FMS, and increase the position of the "amount of hardware acceleration" slidder by one step.
Then run FMS again and test. Repeat the process until you've found your limit.
Have nice flights....
