Is their a configuration setting that will extend the range of the 'clear' terrain around your plane and push the 'blurry' terrain farther out from your plane? I find that the roads in particular a a little hard to follow when flying low and slow as they go blurry to soon in my view and then blend in with the rest of the terrain.

Got Anisotropic filtering on?

LOD_Radius=5.5 (instead of 4.5) in fsx.cfg

I use LOD radius of 8.5 which I think is about the optimum. Depends on what your machine will handle though. Blurries are caused by a system not keeping up with the terrain textures wanting to load, so on a marginal system, it's sometimes more effective to turn some of the settings down (excepting the LOD radius). The system can also be overloaded by using too much anti aliasing in the videocard software. No need to go above 8x. Shutting down background processes can help reduce system load. Sometimes certain virus protection programs try to scan all of the texture files being called and can seriously slow down texture loading. Try running with the anti virus off (disconnect from the net first). Defragging and optimising your disks can help. Mydefrag is a good free program which does a great job of this (but you need to let it take its time). IAN

With all due respect, 8.5 is really extreme and will bring most regular systems to their knees..

Depends on what you call a regular system I suppose Bert. I regard my system as pretty pedestrian by todays standards. I can't get much beyond 8.5 on mine without causing problems. My last sysem (Dual core running at 2.8 GHz + 7900 Nvidia would only allow me to go to 6.5). Saying that 8.5 is optimum (subject to system capability) places the LOD close to the overall level of visablilty available within FSX as I undrstand it. Other things worth trying are increasing the fiber rate to something around 1.00. This seems to improve the clarity of photoscenery, but it can introduce low framerates and stutters if you go to high for your system. Lowering the framerate limiter is also an option as this gives more computer power to rendering the scenery. If your machine is good enough you can try the usepools=0 tweak which I understand uses the faster DRAM video memory (works for me, but works best if you have a 1 or 1.5 gig videocard. Cheers, IAN

Thanks for the info guys. I tinkered with both LOD_RADIUS and Anisotropic filtering last night and both have helped alot. I am very happy with the results. Thanks for all your tips!
