Hey guys, I've been having issues for the longest now with flight sim x, I tried re installing, formatted pc, re installed win 7 ult, tried all nvidia drivers, ran it as administrator, got my gtx 480 replaced, ran it with directx 10 preview and without it, I tried many things and I still get the same problem.I built a PC a few months back so I could play FSX, I got me a cooler master mid case with a power supply of 650W, a GTX 480 a i7 950 @ 3.07GHz, nothing is overclocked with a sabertooth x 58 motherboard and 12.0GB DDR3. My OS is Win 7 Ult 64 bit. Well performance is great but first I started having the ntdll.dll and got even more frustrated and the I started running the game as administrator and as of right now, it works, but when flying usually after the first landing or maybe 10 mins into the game, if I try to open a window while flying for example, If i hit esc and then back into the game or option or whatever, my graphics go wild. Here are some pics. I'm using UT2, Airbus X , Quality Wings 757, FLy Tampa KMCO and KJFK, Wilco 737 and E-Jets, FS Pass X, it does it with all add ons and also with out add ons.... Going insane here... :(
