I had the same problem.Not only did it shimmer, the buildings were spinning like a top.All I did was reduce the mip/map slider to 4 (I think) and that cured it. Took off from LAX. Those buildings didn,t look realistic at all spinning around like that, my grandaughter thought it was funny as hell!Best

Well I used the tip above and tried to set my anisotropic filtering to 16X in the ATI video settings panel under DirectX and cleared the "application controlled" box. What a difference! I got a WHOPPING 5 FPS increase!For my first time ever, the 737 VC in high polygon count scenery/traffic hasn't gone below 16-18. The 2D panel hardly goes below 20.Interestingly enough, no marked difference in FPS at 1280 x 960 and 1600 x 1200 (32 bit).I've increased FPS by about 10 on average by making the two changes here:- AGP aperture to 32Mb (set in BIOS) (added 2-5 FPS on average)- changing Anisotropic setting to 16X from application controlled (added 5FPS on average).My other video settings:- AA 4X (not application controlled, set in the DirectX panel)- AA turned off in FS video settings- Filtering to trilinear in FS video settings- Hardware T&L on in FS video settings- MIP mapping set at 5 (any higher and shimmmers like crazy)- 1600 x 1200 x 32 resolution- 8 light sources- Smartgart enabled (fast writes on - only because AMD/Nforce seems to like that better)- 8x AGPMy specs:AMD FX-51/NForce3 in dual channel config, 1Gb Corsair mem, ATI 9800XT.Hope this helps,

Yes, this AGP aperture size is an interesting setting and I think it can be very individually what value will give you the best performance. Personally I've also set it to 32 but honestly I really haven't noticed any real difference after going from 128 to 64 to 32.

That was exactly the method I used but when running the installer it didn't seem to do anything and I figured that was because it found DirectX to already be installed.Now everything works fine so I don't want to mess around too much if not neccesary but maybe I will give it another try when I have reason to do it.Cheers,
