Hey Guys, that was exactly what i was looking for. It has definitely answered several things for me. However, it has also left several gaps in my understanding ( often the case !! )It also leaves unanswered my querie regarding some textures even quite nearby not displaying their max resolution. From reading the article, I am going to try the mipbias config file entry for effect. I am also going to try and play with the lod radius setting. At the moment I have it set at 8.5. ( I thought the setting would force high res textures further out as well as nearby, kind of overuling any display of lesser resolution textures, but it does not work exactly like that...) The article implies that this should be virtually unrunnable, but I have not noticed any ill effects. One thing that has occurred to me is that if you set the level too high, the sim may struggle loading the hi res textures close up, which may be what I am noticing. I will have to try and balance the effects against each other. Let me play and report back and thx for the heads up.It was also talking about video memory, does that mean that a video card with more memeory will be better at loading and saving higher res textures? I was looking for an excuse to get a card with 2GB of memory..... :( mark

I started getting the 'blurries' when I changed over to the TripleHead2Go Digital, and my set up is now more 'zoomed' that it was on a single (22") monitor.There is definately a correlation between the 'zoom' level in FSX, and the blurries. What is your zoom set at when you're flying? Further out (ie 0.40) tends to give less blurries than further in (ie 0.80).The most effective tweaks I found to address Blurries, or slow sharpening textures were:-- Adding the 'MipBias=6' to the [Display.graphics card] entry in the fsx.cfgand,- Adding the 'Fiber_Frame.....' entry, and setting it to 0.37 (default is 0.33), and as a general rule, going lower biases towards FPS, and going slightly high biases towards faster texture loading).I have also found that setting AF to 'Trilinear' in FSX, gave significantly better performance that setting it to (the lower setting of) 'Bilinear', which I found odd. I guess my 8800 512 GTS prefers Trilinear. As a point to note, setting AF in FSX to the highest setting of 'Anisotropic' pulled performance and smoothness right down, with no visual benefit.In Nhancer I set AA to 8xQ, and AF to 8xI get really good, non-blurry results from this set up in FSX, using a 3870x1024 resolution, and I too use a lot of photoscenery (particularly the Horizon UK VFR Photo scenery series).Good luck in your quest!David R

Hi David, thx for the reply, how do you adjust the zoom level? I use track ir4 BTW.One point, I thouht the fibre frame entry was redundant after sp2 / acceleration?

Mark,The "+" and "-" keys control your zoom level in the VC (unless you have configured them differently) and you are correct, you do not use the fibre frame tweak with SP2/Acceleration.

Hi guys, I have been doing some testing and the results are a bit inconclusive. I have tried adding the "mipbias" setting to my config and have tried values from 1 to 9 , but could not see much difference on any setting. I have currently got lod radius at 6.5.No matter what i change, I cannot seem to affect the rate at which the highest rate textures appear nearest the plane. Do I need to enable mipmapping anywhere else? Can anyone say what the upper range of this value is and exactly what it does? Can anyone say what is the thing I need to change to force this quicker? loking at the explanation as to how FSX uses the lod radius value, I understand that if you set it 4.5 and above, FSX will load the highest resolution ( 1.2 metre per pixel) textures in the area round you. The size of this area varies according to the lod radius value. But i am seeing lower res textures, with higher res textures snapping in later. So FSX cannot be loading the high res textures first, despite it being directed by the lod radius setting.....

Mark,There is no magic bullet to force this quicker and changing your LOD Radius to 6.5 is just going to tax your system even harder (if your system can't sharpen textures quick enough to your liking at an LOD of 4.5 it most definitely will not happen at an LOD of 6.5). Have you zoomed your view out as suggested?? It has a profound effect on the sharpness of ground textures. FSX normal behavior is exactly what you describe (textures snapping from low res to high res). No matter what, you will see this type of behavior somewhere around your aircraft.

I cant find zoom in any of the key actions listed> If i press shift O, I can zoom my FOV in and out with the mouse wheel, is that what you mean? Does this only work in the cockpit? Most of the time I like to fly with an outside view, admiring the scenery!I appreciate what you are saying, and while a magic bullet would be nice, that is not necessarily what I want, I am just trying to understand what the different config line alterations do, and how they interact with each other, so I can establish what works best for me and my hardware and my vision of how I want FSX to look and run. For example, many of you guys love the standard scenery and autogen. I personally think while good, it looks cartoony and I much prefer photoscenery with no autogen, for the maximum reality. So my FSX is going to be set up very differently from someone who wants max autogen etc. What i am seeing is NOT the "blurries", but rather a delay in the injection of highest res textures near to the point of view. Its wierd, because, as I said, it is not a blanket thing, rather small sections in various places in the field of view. If you pause the sim and wait, you can see subtle changes as the the scenery appears to "morph " into crisper definition in various small areas, over a period of seconds. Sometimes, this stops, and will only carry on if you unpause the sim and move the plane a bit. There must be a setting that controls this. Something in the game code fetches the textures and loads them at a determined rate. I guess this also is a function of the .bgl file for the scenery, although I have no knowledge of how that works. If I can figure out the effect of TBM, bufferpools, Lod radius and mipbias on the sim the way I am using it, then i can decide which combination of settings works best for my situation. For example i understand that the bufferpools entry works on the video memory. A simmer with full autogen will have it set differently to me with my autogen on zero, as in his situation, it can reduce stutters. That may not be a requirement for me, and perhaps a different setting with no autogen will give better results for my situation. I would appreciate finding out the effect of the above variables and how they interact. I will go and do some digging, but if anyone knows, please chip in!!Thanks for all of your input to the discussion so far. One of the reasons I like this sim so much is that here is so much to learn and understand and such a great community with similar yearnings to help you!cheers,Mark

Mark,What Sargeski says is true. Altering any settings is not going to affect the loading of textures closest to your aircraft. In fact they could easily make it worse.Can I ask which particular Photoscenery you are using ?I use the Horizon Generation X scenery for England and Wales Which Has Two sets of textures. The main coverage is at 2.4 mpp and these textures are mip mapped. There is also a set of High Res 1.2mpp un-mipped texture which operate immediately around the aircraft. You sometimes see a slight out of focus effect at the join of the 1,2 and 2.4 textures but the textures closest to the aircraft are always sharp and clear.Rod.

Hey Roddy, the pieces of the puzzle gradually fall into place!! I am using VFR in the UK, MegasceneryX and megasceneryEarth in the USA. Both are pretty good, and I have to say, I am being picky really, but only because when something looks that good, you notice the small imperfections more. How far out do the 1.2m (1024) textures go? I have been playing around with settings all afternoon and no matter what I do, i cant change force the sim to load ALL of the high res textures, I still get the "morphing" round the plane. I have to say this is more noticable in the megascenery than with the VFR. its kinda frustrating, as I know its there, it just needs to be unlocked!! If I pause for 15 seconds, they all pop up nice and crisp. looking forward to hearing more......!!!

Mark,What you are seeing is indeed the "blurries" and the delay in the injection of the highest res textures near the aircraft is normal FSX behavior.To zoom your view in and out the stock key commands are as follows:"=" the equal key (do not press shift)"-" the hyphen key (next to the equal key, do not press shift)If these commands are not zooming your view in and out, then you have changed the default key mappings for FSX.--Bob

One old simple thing to do is set max FPS to something like 20. Then see if thi might help. Speed of your scenery viewer (aircraft) should be less than 200 knots.
