Well I was up at 50k ft, with the ufo, looking around, max fov, and it isn't as bad (sure there's some redrawing visible at the edges) but it certainly was worse with any decrease in any of the buffering options. > > Visible range hits really hard >25 km here.

(the way trees are done, only with a (or several) horizontal plane(s) added) These might work better for bigger structures like cumulonimbus, and such, too, as you can "control" the shape a bit. (no fancy shader needed ;) ) BTW: A question for our more knowledgeable graphics coders: I don't know if and how this is affecting the VRAM usage, or gpu performance, shouldn't we have the default wrapping mode for textures on models (not terrain) set to clamp, not repeat (as most usualy use parts of one bigger texture, or it's extents), and use repeat only where that's needed? (that is if that's what the <wrap-s/> <wrap-t/> tags control in the texture definiton inside the effect files) Emilian ------------------------------------------------------------------------------ Enable your software for Intel(R) Active Management Technology to meet the growing manageability and security demands of your customers.
