I am currently running Windows 7 ultimate x64. i installed FSX deluxe and FSX Accel. last night. When i run FSX without DX10 preview i get terrible framerates (4 or 5 FPS)and distorted sound for about the first 2 minutes but after that the sound fixes and i get 38-40 FPS until i take off or pan around the cockpit, then its back to screwed up sound and low FPS. If i check DX10 preview this only happens if i pan back and forth quickly in VC but fixes in a matter of seconds. I have the latest Nvidia driver. I tried running in XP compatability mode, Vista compatibility mode and also made sure i was running FSX as a Administrator. I even have the desktop set correctly (disabled Aero). Why will FSX only run with DX10 preview enabled. I dont want to use DX10 because the runways flicker and change size and plus it lowers my FPS by about 10. Any suggestions on what could be causing this? Anybody else experience these issues? My PC is a dell Optiplex 745 Dual core (2.4GHZ processors) 4GB of Kingston memory, XFX 9600 GSO fatality GPU with 768mb RAM, and a Soundblaster XFi Xtreme Gamer soundcard. Also FSX is on a seperate 250G HDD. FSX worked perfectly using windows XP Proffesional. Thanks in advance for any help
