In FSX, do you run with the FPS limiter (FSX one or external) or you've set it to unlimited?

The only time my GTX470 and now my GTX480 had crashed FSX was when my video card overclock was not completely stable. However that was with the original 197.41 drivers. I just installed last night the 257.21 but havent had the time yet to try FSX with it.Are you running your card at stock speeds?

My turn will come up soon in the EVGA step up program to exchange my 470 to a 480. I was wondering if anyone here had the chance to try both with FSX and if there was a notable difference between both in FSX?I really wanted to buy a 480 at launch time but they were out of stock, so I got the 470 and registered in the evga step up program. However I really like the performance of the 470 and now debating if the step up is worth it (for +/- 170$).thanks

+1 on the PSU. With my 930 clocked at 4.4 and the GTX 470 I am seing peak wattage (measured at the outlet) of 584 watt so I would go with a 750 watt PSU to have a little more margin

Some people experienced the same issue with the Geforce 200 series. You can check this thread, the solution might apply as well to the 400 series. HowTo: Prevent GTX 200 Series Downclocking

But the 480 has DDR5 memory and the 285 has DDR3 memory. At stock speeds the GTX285 has a 159GB/s memory bandwidth and the GTX480 is at 177GB/s.

When you'll get the 480, please share the 470/480 comparision results. I am tempted to do the step up as well but will wait on your results before making a decision :)thanks!

Very nice screenshot and IQ! congrats!I love my GTX 470 too. A world of difference with my GTX 275cheers!

Exact same chip but the 960 are binned higher. However that does not necessarily means a better overclocker for above 4ghz. vcore requirements tend to increase quickly above 4ghz no matter what chip you are using. Definitely! I upgraded from a quad Q9650 at 4.4ghz to a i7 930 at 4.4ghz too and the difference was very very significant.

I tested the same flights twice again in DX9. All others parameters were the same except bloom that was turned off.I'm puzzled by the results. Not much difference in the numbers also while flying I could not notice any difference myself. Unmodified FSX.CFGMin FPS: 14Max FPS: 63Average FPS: 40BP=0 FSX.CFGMin FPS: 17Max FPS: 63Average FPS: 42I did some flying around KSEA all sliders maxed out with both config and could not see any performance difference too.Anyways, the sim feel so much better with the 470 compared to the GTX275 so I guess tweaking is less of an issue now.cheersMarc

Hello all!I just had some time to test ******* tweak with the GTX 470. Not sure I used a scenery that was complex enough, but anyways here are the first test results.Flight description: Kai Tak runway 13 approach, from IAF to gate. Night time. Flight time 13 minutes approx.Weather: broken at 6000.Scenery used: Fly Tampa Kai TakPlane used: PMDG 747-400Other addon: REX clouds at 4096x4096 DXT5FSX settings (summary) : DX10 mode, bloom on, water 2.x low, very dense scenery complexity, autogen dense, frame rate unlimited.Video drivers used: 197.41I used fraps to measure, min, max and average frame rate. I did the flight twice, once with an unmodified FSX.CFG and another time with the two modifications ******* gave me in this thread. I also forced vsync to off in nVidia control panel.unmodified FSX.CFGMin FPS: 23Max FPS: 75Average FPS: 35FSX.CFG With tweaksMin FPS: 25Max FPS: 74Average FPS: 36Both flights were awesome to fly. Great performance and not one stutter in both. Really smooth. From what I read here, I was expecting more difference. Maybe I should try with another scenery location, JFK for example.what do you think? comments? suggestions?cheers!MarcEDIT: I could not help but do a few external views during the approach, that explain the "high" max FPS. While in the virtual cockpit, the FPS were always right around average FPS without any jumping up or down.

Dont worry, you'll be able to overclock it yourself way above the SuperClocked speed. Looking forward to it :) I didnt have any time for me last night to test the tweak on the GTX470, business is incredibly busy these times. Hopefully I'll be able to test it tonight too.cheers!

Do you have a link to a thread that lists the others tweaks? Last friday nVidia released version 197.41 only for the 470/480. that's what I am using, but, yeah, we are still some time away from mature drivers.

Right now I am using an un-modified CFG that FSX has rebuilt after I deleted the old one. I havent tried any BufferPools tweak yet. I'll do some more flying with the "plain" CFG to get a good feeling on how it perform and later I can test with different BufferPools options and report back.

I cant say for the 480 but I installed my 470 last night. I played a few hours of FSX with it and I like it very much. I've seen a much better difference going from the GTX275 to the GTX470 than when I went from a 8800GT to the GTX275. No huge increase in framerate, (I would say about 10% above the GTX275) but much smoother without any stuttering. Need to do lots more testing toughNoise/Temps are not really an issue in FSX as the card doesnt get much hot while running FSX. The fan stays at the default 40% or barely increase and is pretty much silent at this speed.In other games it's different tough, in Bad Company 2, it gets in the high 80's and the fan increase in the 60 to 65% range. Never seen the fan go higher than 65%, which is not silent, but not too loud. Overall I would say that the 470 is similar to temps/noise profile I was getting my GTX275. Slightly hotter/louder but not much.
