It still plays smooth though no jerkiness or anything.
That is the goal! To get it to fly smooth without jerkiness!
FPS means nothing it is a number that people get in there head that bigger is better and a argument that has been here many times past.
Over 20 FPS and you can't visually see a differance the human eye and mind won't process it, so what is the point aiming for the ultimate in frame rates?
You sit and stare at the red numbers in the upper left and pay no attention to how the sim is flying," oh crap 25 FPS this sim sucks!" is your plane acting like a slide show? no.
Try flying sometime with out the FPS displayed, you won't be able to tell if your getting 20 or 80 FPS or whatever, the only time you'll know that your FRs are way to low is when it starts to sputter.
This is a proven fact that locking your FPS at a lower number will help performance (20-25) your sim won't be trying harder to meet the higher numbers.
Looking at and reading all the "benchmark" numbers that are always posted everywhere (and guru3d is all anyone talks about) really doesn't make sense because I have yet to find any of help because no one ever seems to tell you about FS9 benchmarks, they always benchmark FarCry,Doom, Unreal etc. all of which are totally different style games on different style platforms compared to FS9. Just because a card "rocks" on FarCry doesn't mean it will "rock" on FS9 totally different in more ways than one!
Another thing people neglect to mention is computer maintenace, clean out your junk and defrag often all of this helps your computer run better. Shut down all un-needed apps and processes either buy"Ctrl-Alt-Delete" or some other utility like EndItAll. Increase your page file.
Don't ever expect that your computer will perform the same as someone who has a identical setup! No two computers work the same even if they are carbon copies!
So you now have some more ram.
Focus on a video card upgrade, Congo might slap me for saying this but try a FX 5200 not to expensive and with your PC might be great if not great a BIG improvement. (i use one and it works great and just to be like the rest can easily hang out at 39+ FPS with settings maxed, not that I would know if it wasn't for a number being shown in the upper left

)
Don't try and aim for 80+ FPS no point and it won't happen!!!!!! Try locking FPS 20-25.
Clean out all the crap off your hard drive, then defragment, then defragment on a regular basis.
Run regular virus/spyware scans.
Try lowering your settings a hair, don't ask your computer to try to do something it won't..
You'll find some of the biggest performance increases will be the ones that don't cost anything!
