Hi experts, Can you give me some advice as my knowledge is a bit limited once I get into Hardware stuff. I recently upgraded my Graphics Card to a ATI Radeon HD 4650 AGP 1Gb to improve FS9 performance and it does seem better. But I am getting conflicting views from friends of mine. They think It should be even better than it is. I can run the "Century of Flight" flights with sliders for weather, clouds traffic etc. at about 70% and 25- 27 frames per second. Once I switch on anti liasing, shadows etc. it slows down a bit but is still better than before. I have updated all the relevant drivers etc with no problems. So my questions are:1. I am told I should unistall the re-instal FS9 to get the new card to work best? Why?2. I am told it is not necessary, Graphics card will automatically improve performance.3. If I uninstall etc. Will I lose my saved flights or settings?4. Are there any other tips you can give me to get the best out of FS9. Thanks in anticipation ianmicker
