Hi,Just thought I'd share an interesting find. I set both AA and AF in the display driver to "Let the Application Decide", then I turned on AA in the sim and set the texturing level to "Trilinear". Whilst playing I noticed that in the distance the textures were blurring horribly. I remembered it working fine in FS9 with the setting of Triliear, but I thought "oh well I'll set the filtering level to Anisotropic".So I set the filtering level to Anisotrophic and gave the sim a whirl. To my surprise I noticed zero performance loss so was quite happy, but whilst flying I also noticed that the textures in the distance were shimmering horribly! It almost became unbearable, and I was thinking that there must be a way to reduce that without getting horrible blurries in the distance.Well, there is a definite solution that works a charm! Just so you know I'm using a Radeon X800XT card with the latest drivers, so you may well get different results when using a different card. I set the AA to 4x in the driver, and I set AF to 8x. I then turned off AA within the sim and set the filtering level to Trilinear. I once again took to the air and to my relief everything was perfect! No awful shimmering of textures in the distance and the textures still looked clear and rock solid all the way to the horizon! Oh, and the AA works fine and I have 0 performance loss from the settings.So there you have it, if you are finding AF in the sim gives you bad shimmering and Trilinear is too blurry, try setting AF in the drivers and setting the filtering level to Trilinear in the sim.James

Hi James. I have the same card. What version drivers are you using? Thanks, regards, Bob.

i'm happy for you if it worked. i went through all possible combinations on my card and the best is merely less horrible than others :-)i find the shimmering depends hugely on your altitude, angle at which you're looking at the water or ground and how high the sun is above the horizon. i assume you were doing your comparisons with the above three values constanti guess i'm still waiting for that magic hidden parameter (a.k.a. mipmap level :-))

I have the same graphics card, and have the sim performing very well for the most part at pretty high settings, but the long distance blurries were spoiling the overall effect for me too, and changing the filtering method gave me the shimmering effect too, it was unbearable (it does depend on alititude/angle etc., but the blurries were better in most cases! lol).This change worked very well on my system, and absolutely no noticable impact to performance --- generally I hate moving sliders on the graphics card that 'lower' quality, but this one works!Great information James - thanks for posting it!

I have the same card and had noticed the shimmering effects as well - I tried fiddling with the settings and came up with the same configuration you suggest. It works very well on my PC.Have you tried the shader 2 tweak for this card as well? This produced a big increase in FPS for me (nearly doubled it). The original thread is at:http://forums.avsim.net/dcboard.php?az=sho...ing_type=searchI'll post my x800 display.cfg settings here when I find them.

I'm using the latest ones, Cat 6.9James

Here are my display.cfg settings for an ATI Radeon X800 GTO ;----------------------------------------------------------------------; ATI Radeon X800 GTO;----------------------------------------------------------------------[00001002:0000554F:ati2dvag.dll]Shader20Plus=13UseShaders=1[00001002:0000554F:ati2dvag.dll.1]Shader20Plus=13UseShaders=1You might need to check the card ID (554F) as suggested in the above link as it might be different for your exact card. The easiest place to find this is via DxDiag (try start->run and enter dxdiag). The card ID should be listed in the Display Tab, under Chip Type.

Jimbo, your settings are what is generally recommended on many FS9 (and probably now FSX) FAQ's, and I've found those settings to be the best for quality and performance.FWIW I'm running the latest Omega drivers, based on the ATI 6.9s

I went from an old ATI to an Nvidia 7600 GS and the difference in filtering is pretty amazing.The ATI produced a decent image but there was still a fair amount of shimmer even with anistropic filtering. The Nvidia renders almost shimmer free with FSX trilinear and driver AA. It might just be the ATI i had...was a Dell cheapo x600 i believe...FWIWYMMV
