Hi all I have FSX with the Acceleration Pack and I also have the NGX installed Today I was flying with my friend and I was constantly experiencing a problem where FSX would continuously freeze for about 5 seconds and then resume I have spent the entire afternoon playing around with various settings but I cannot fix the problem The problem occurs a good couple of times a minute and it seems to do it a lot less when I completely lower the scenery settings ++++++++++++++++System Specification++++++++++++++++ Intel i7 860 2.8 GHz4 GB of DDR3 RAMXFX 5850 1 GB GPUWindows 7 64 bitAll drivers up to date Thank you in advance 787
