Anyone have a 7900GT or GTX? I'm curious as to what settings have proven optimum. I found I had a lot of shimmering, until I turned up the "Image Settings" to "Very High" in the advanced settings. Shimmering vanished. But mid- and distant scenery is more blurry than I like . . . Changing those doesn't seem to have an effect. Other settings:Hardware AA=4, software=0AF=16MipBias=8RenderToTexture=TRUETransformAndLighting=TRUE1280x1024x32[TERRAIN]TERRAIN_ERROR_FACTOR=96.000000TERRAIN_MIN_DEM_AREA=10.000000TERRAIN_MAX_DEM_AREA=100.000000TERRAIN_MAX_VERTEX_LEVEL=21TERRAIN_TEXTURE_SIZE_EXP=8TERRAIN_AUTOGEN_DENSITY=5TERRAIN_USE_GRADIENT_MAP=1TERRAIN_EXTENDED_TEXTURES=1TERRAIN_DEFAULT_RADIUS=3.500000TERRAIN_EXTENDED_RADIUS=3.500000TERRAIN_EXTENDED_LEVELS=0

Well, the typical tradeoff is your MIP settings in MSFS - if the lower they are, the more likely you are to have muddy textures (not "the blurries", but just bad looking things). The higher it is, the more likely you are to have a lot of shimmering. Looks like you have it pegged up at 8.Most folks, even with super-high-end systems, recommend a MIP setting at the midrange - 5 or 6 - to nicely balance shimmer with ugly. It's not really a performance setting but rather an image quality balance setting. For mid-range textures, you may want to set TERRAIN_EXTENDED_LEVELS to "1". This (I believe) will kick those TERRAIN_EXTENDED_RADIUS setting into effect, which I think will add a ring of mid-range textures. Your MAX_VERTEX_LEVEL setting is also a touch high - if you have the CPU to handle it or the personal preference to use it, great! But you may wish to step that down a notch to free up some processor time for the texture engine. Lots of "I think's" and "I believe's" in my post, so take the advice with a grain of salt, but try 'em out!-Greg

Thanks for the response, Greg. Indeedy with the MipBias at 8 theoretically I'm getting minimum blurries, and maximum shimmer. But with the GPU Image Setting at "High Quality" I get virtually no shimmer.Thanks for noticing TERRAIN_EXTENDED_LEVELS at 0. It doesn't seem to matter if this is 0 or 1 or any number, the result is the same. So I'm curious about that. Performance is not an issue, I've virtually no stutter and lots of FPS to spare. The scenery is quickly resolving to maximum LOD> So I can easily use TMVL=21.Thanks again for the thoughts . . . Jon

Is that what TMLV does - controls the speed of terrain appearing in max LOD?One of the issues I am trying to resolve is lower levels of detail appearing close to my aircraft. I have it set at 21 as is recommended buy FSG for their mesh.

As far as I can tell, most of those settings only affect how the mesh is handled, and have no direct effect on the textures or how they are mipped or how the mips are blended.scott s..

Jeff, as Scott says, TMVL relates to the mesh, and will determine the highest resolution the mesh will resolve to, ie 21=19m, 20=38m, etc. Should not affect "speed", except that for some (here I speculate), the higher resolution may use more processing power and take resources that would otherwise be used for texture level of detail, autogen, etc., and so the display might take a little longer to become stable.Jon
