fsx

okay, everything backed as same as before but only a difference now is it on the Win7 64bit.
well, lets say result first. There was bit improvement after I add "AffinityMask" at fsx.cfg to 15 for quad core. but only a bit...

Now, I reviewed configs and found that the performace very much improved when I change filter to Anisotropic from Bilinear, then disabled light bloom.
This is work. fps gets 20-60 all the way.

Today, 4GB of DDR2-800 has been returned by replaced with new set. Thank you very much "MVK" who is a reseller of GeIL in Japan.

With current 2GB, 1.66-1.8GB continusly used when FSX running.
