I doubt it too. 10 fps is useless in an area where I'm at 40-60 fps. Where I want to see an increase is in NYC.The performance killers are the speed of the airplane & airplane, AI traffic, and car traffic. All related to CPU. The cloud themes and weather have some effect, but it's not too bad.I run at 32xS, but I can run it at 8xSQ and I see no change. I just like 32xS a little better.

I find one of the biggest hits in performance is cloud density. I turn this down a bit when flying in complex aircraft with add-on scenery and it makes a huge difference with gps and smoothness.I also doubt ypubwould see a huge increase in performance from a 480 to a 580

Stephen,As you are having a very nice fast computer and a very fast graphics card, I was wondering why you don't upgrade your memory ?I had 1600mhz in the past also .After having replaced them by 1800mhz memory I noticed more fluidness and about 5% increase in framerate.(I did several banchmarktest using FRAPS ).Just my 2 cents.

I only run my i7 and 3.2ghz because I've tried OCing but am apparently missing something as my sim isn't stable after. I also see teen FPS in high density areas, and I run zero traffic. But the 747F at an addon airport in a big city, 10-20 fps. Once I get in the air I'm around 20-40. This is all in really bad weather though usually rain or snow, and max sliders. The 580 to me has been more stable and more smooth, not so much a big increase in frames, with my 285 I used to see fps in the 8-12 range in this scenario though. So it is a nice addition lol

Hi Gerard,Which OCZ model of 1800 memory have you installed, and what is the cas? I know these G.Skills are very very fast at 1667 with low 6 cas numbers. I think that they are plenty for this overclock. I may be wrong on that and ready to listen and be better informed.Kind regards,

OK , Finally my EVGA 580GTX SC received ,this is preliminary tests result on my current CPU speed ([email protected]) , this is my 2 little scenarios:PMDG 748 on VC ,EDDF, weather Thunderstorm, 12:00Local time (Aerosoft+GEX+REX+UTX):285GTX: 19 580GTX: 22580GTX(BP=0):27PMDG 748 on VC ,KJFK , weather Thunderstorm, 00:00Local time (FSDT+GEX+REX+UTX):285GTX:14580GTX:16580GTX(BP=0):17285 had Bufferpools/RejectThreshold tweaks and 580GTX hast “Highmemfix” in first result and “Highmemfix+BP=0" on second.I have not any idea about smoothing, not compare it yet.Regrads
