Are there any SP2 performance tweaks I could use on my old PC (Athlon X2-3800+ @ 2.5Ghz, 2 Gb RAM, 6800GT/256M) ?SP2 seems to give a little boost, I installed GEX+UTX-USA which if anything also seem to give a tiny boost in perf. (and huge boost in visual enjoyment), last one installed is TreeX v2.1 / Performance Textures.With all this I can fly the C172 at 1m / 16 FPS locked w/o too much blurries, but this is without any trafic (air/road/see) and very minimal 3D clouds.For example, I am wondering if there are other replacement texture for clouds / autogen / whatever that would help performance, just like TreeX/Perf. does for trees.Thanks in advance,D.

The only real tweak, I'm afraid is what a number of us have applied... it is called cash (to buy a new, faster system).Other options are to fly FSX with options scaled back, or a better choice, fly FS9 with options wide open..
