Hi Guys Just Rescently i purchased a powerful gaming system . i install a fsx and run in full setting the fsx was very smooth. there was no problem at all suddenly one day my fsx just got freeze and when i load a flight it freezed and halt. then i thought file must have been corrupt. i did repair and again clean setup and tried again well it runs but it was not like before the smooth. it was quite jerky when i rotate my camera from vc or in wings veiw its so jerky then i try lowering the setting then still the same problem. i did update my graphics driver which ATI radeon 5870 x 2 but i couldnt find any difference. this thing happened to me before as i noticed but i dunno what happened now. please could u let me know what is the problem behind it. if u want to know my spec of my computer as follows : Liquid I7 Black Pearl (NO MONITOR)CAS: Coolermaster HAF 932 Full-Tower 420W Gaming Case W/ Side-panel WindowCS_FAN: Maximum Case Cooling Fans for your selected case [+10]CPU: (Quad-Core)Intel

I would rename the fsx.cfg, restart FSX and let the config rebuild. What OS is installed?Best regards,Jim
