Revised Optimizations for the 747-400X post SP2

Hello PMDG Staff! There have been a lot of new ideas as to how best to tweak/optimize FSX following release of FSX SP2. A lot of AVSIM posts seem to encourage doing little to nothing to the FSX.CFG (this is generally speaking, not necessarily for the Queen). But when I try that out, it's not near as good as I would like and have come to expect from a Quad Core PC and 8800GTX card.I think your earlier tips in the OPS documents are better than no tweaks to the .CFG at all, but thought I'd ask since I haven't seen post-SP2 recommendations in this forum. If you have discovered some revised tips, I'm sure a bunch of us would appreciate it. If your previous tips still apply, that'd be helpful too. Thanks very much.BarrieEdit: Just to clarify, I have Vista 32-bit.
