Ideas???!!!!!

[757200ba]

Hello!!.I know that  the question "is this a good fs9 pc?" There are zillions of answers . But i just made a fresh installation of windows and fs (fs on secondary).I dont have any other ads.My fs is no maxed out.
i have it like "dense" on scenery, aircraft i have all flags( default).Hardware 1280*1024 32 (i saw here that this res. is good (?)), global --massive,filtering-trilinear, no AA, mip mapping 8, hardware rend 8.
It might miss something for a good advice i think.
My fps are limited to 20.When i start in Tacoma i get scenery all complete, but the airplane grey, after a few seconds it gets ok, if i rotate the plane the fps go from 20 (it never reaches 25) to 8.
I know that all this sounds confusing( and my English is not that good), but dont you think that my pc is "enough" to deal with fs9?
What to change?I know its hard, for you but i know there are loads of "Obi ones" there.I dont know what else i can do.
Please help, ideas tweaks,anything!! :-/ .
This is my 'contraption"
Many thanks to all

What are the speeds of the two HDs?

I think they are both 7200, 8mg cache (utdma 5) (everest).
Many thanks

try these in the following order:
1) lowering resolution to 1024x768 32
2) lower scenery from dense to something else
3) lower from massive global to something else
4) try bilinear filtering instead of trilinear

you will never reach 25fps if you have the limit set at 20.  If you want to allow your computer to render more fps try upping that limit or even setting it at unlimited.  In FSX I noticed an increase in my fps when I set it to unlimited from 60.
