So how's the supersampling performance of ati's cayman xt , it should have incredible raw power. Every thread concerning fsxperformance with this card died down without a real conclusion.I am especially interested in supersampling performance while in heavy weather and around major hubs.Please only responses by people who have one. No "I have heard that..." or "ATI $%$ in FSX".

Hello,Well I'm using a 6970 on my new (5 months) i7 system. See sig for details.I'm running a triple monitor setup, eyefinity, and would never go back to anything less. How is it is heavy weather??, terrible. I have FlyTampa KBUF, KBOS, KTPA and the card works great, unless the weather is poor. The only way I have been able to get decent frame rates in heavy weather is set the AA at 2x (SuperSampling is always on or I get horrible shimmering), as well as turning water down to 1x High. If I have AA at 4x and water at 2x Mid or above frame rates can drop to single digits in heavy clouds.I do / have used and tried all the known tweaks including the shader 3 mod. Mind you I do run with 80% of the sliders full right. I have UT2 at 50%. The rest of my addons are listed in my sig. I'm still comtemplating moving to a GTX580 with TH2GO, but it's so expensive, and I never received any solid confirmation from the post I had here that things would be that much different to warrant the crazy cost.I suppose if I ran just one of my monitors 1280 x 1024 and turned down some settings, and always flew with "nice" weather it would be a lot better, but I didn't spend over $2000 to turn scenery settings down, so I turn down the water and the AA so it's not a slide show when the weather is messy.Glen

Ah, the endless problems with FSX, multi this or multi that!But thanks for your post Muskoka, this is exactly my worries about choosing Eeyfinity for FSX: AMD Radeon is not good for FSX!!!But I like Eyefinity, and I don´t like TH2GO, I don´t trust all the good things they say about it!So, what to do, Nvidia Sorround, buy 1 more GTX 460 1 GB, and find out it sucks, endless problems, endless...

Well, I wouldn't go as far as saying "AMD Radeon is not good for FSX!!!". More like AMD Radeon is not as good for FSX. But then again many simmers are getting very satisfactory results using them.I have both the AMD Radeon 6970 and the Nvidia 580. So I was switching back and forth to see what the differences were. With the AMD card, I never seemed to have the issue with clouds dropping frames to single digits other than the fact if you load up lots of layers FPS will naturally take a hit. Seemed those who use the Shader3 mod fixed those issues who had them.With the Nvidia card, it seems you have more choices with adjustments and different settings when you use an applet like Nvidia Inspector. I am using the 580 card for now and will do so probably until MS Flight comes out. Reason being I get less "shimmer" with trees and 3rd party add-on objects (airports, etc.), with this card than I do with the AMD card no matter what I have tried.Plan was to use Eyefinity but again, I am holding off on multiple displays I think now until MS Flight. I'll test both again then buy a 2nd card for either SLI or crossfire. Hope I don't have to wait much longer as I am just itching to get into wrap-around simming. ;)

Thats not fair at all to say that ATI isnt good for fsx. My esperience with Nvidea has been great, but so has ati. I run a 6970 2g and it runs wonderfully,as did my 5850, but running 3 monitors was taxing for it. So I wont go back to Nvidea because of the 3 screen thingy. I run all Orbyx, a few Aerosoft sceneries, many addon aircraft and helo's, ond also many utilities like, Trackir, saitek instrument panels, My Traffic X, helitraffic 2009, ezdock, Passengers X, REX Overdrive, 2 sound cards-one for all sounds-one for atc in my headset. Probably a few others I forgot. All sliders to right ex. autogen @ very dense, and water @ highx2. Now fps is another thing 20-25 respectively. Smoothness is all I care about. I ran fsx with all addons and sliders the same before I o'ced the cpu to 4Ghz. WOW did that make a difference, it seems' that an i7920 at stock clocks actually bottlenecks the gpu.( I know fsx is cpu bound, I am judging on the same system with a 5850 with cpu @ default and o'ced) My sig: rampage 2 gene, i7 920@4Ghz, mushkin redline 6 6 6 18-6g, xfx 6970 2g, raptor for fsx, w7 64

I bought the card, had the usual problems finding out about a passive or active DP>DVI adaptor, and of course I got the wrong one!Waiting, waiting... - and in the meantime testing the card, and my advise:DO NOT BUY THIS CRAP FOR FSX, PERIOD!!!I only got it because of Eyefinity, Nvidia cards are way, way ahead of this ugly-monstercard, phew...Loaded KSEA with heavy clouds and got 8-9 FPS, woohaa!Card settings: All the way to the right, anything else looks terrible.Sure hope MS Flight will do better with AMD cards...

Ok, got my Active DP>DVI adaptor, hooked up the 3 x 23" LG LED´s, turned the settings down to this in CCC:AA: 4x Edge-detectAniso: 16xTexture filtering: QualityAA Mode: Adaptive Multi SamplingPerforms absolutely awsome! Now I understand people can´t go back to a single screen when they´ve experienced a "wrap around Sim"!But of course, as mentioned in #6, ATI/AMD just don´t perform like Nvidia, sadly...Anyway, can´t get everything, right now I´m just blown away by the 5760 x 1080 MS Flightsim X!
