Hello All,So I have a Q9550 overclocked to 3.7, 4gigs ram and a GTX260 card on win64. After seeing the reviews decided to get a GTX570. After following the driver removal instructions on Nvidia's web site I removed the drivers swapped cards and installed the new drivers.With the GTX570 installed the benchmarks showed double the power of the older GTX260. So eager to see what FSX could do now I loaded it up. And if I had not put the card in my self I would not have believed it was changed. Really not (1) FPS more, and not the least bit smoother. How is it possible that the card could show such improvements in 3 different benchmarks but absolutely nothing for FSX? Has anyone else experienced this when changing there card. When I went from a GTS8800 to a GTX260 I noticed a big increase in smoothness, not a big FPS increase but smoother.I just don't see the difference here I was expecting from other reviewers.Regards,Ken

FSX is not GPU dependant on, my 480 it rarely pops over 30% usage.

I have heard from a few users that with the 5xx series cards you really need 4+ ghz and possibly a better processor to really see the diference as your proc is likely the bottleneck, not the gpu? Ryan from PMDG had the same problem by inrcreasing his oc and I think he may of did a re-install of the os, he was at a similar clockspeed to you, but on an i7 1156 if that makes a difference as they are both quads.See here...http://forum.avsim.net/topic/322150-so-long-gtx570/

I'm pretty much saturating my GTX285. If I pull any ounce of performance more out of it, I get artifacting and all sorts of errors.Apparently you were nor are saturating your GTX260 nor GTX570.Run your sim for instance with high FPS, 30+, with autogen at least at Normal or Dense, then crank up the Nvidia Inspector to use 8xQ or at least 8xS. I can bet you will see VERY big difference between those two cards.Right now you are probably limited by the CPU, and your GPU is just chugging alongside with it...

Sorry for abandoning the thread, work has been crazy.Anyway Since I could not produce these great results others have seen with there gtx570 I decided it was my Q9550 not being fast enough to feed the monster.So I picked up a I7-2600k ASUS MB and tried it out. WOW all I can say is this chip is awesome. However curiosity got the best of me and I had to put the gtx260 back in for comparison purposes. I really didn't see any slowdown so back to the store the 570 went. Hopefully kepler will provide a big gain. Just for some comparisons my start up at seatac with the Q9550 gave me 22FPS and now with the 2600k (same medium to high settings) I get 33 fps and a MUCH smoother flight. So if you have a decent card, spend the money on a sandy bridge you will love it...

You are definitely not using high IQ on the card. If you pull some decent visibility of LOD 7.5 and 8xSQ in Nvidia Inspector, you will virtually KILL your GTX260. Wanna bet? :)570 kicks 260s &@($* by a longshot if used correctly.

I remember when I had my gtx 285 and I couldn't run 8xSQ. Too much of a performance hit. Same i7 975 system, just a different card.Then I upgraded to a gtx480 and now I can run 32xS. Same system, different card.As for FPS, we all know that FSX is CPU clock dependent. But, pair a 5ghz CPU with slow card and watch what happens.
