Quick and easy way out, compressed textures for the clouds as in .dds textures :D (sorry about that, couldn't help myself :P) I've played around a bit with the config settings, the greatest effect was noticed with the visible range slider, and max clouds in loop. The most efficient way seems to have everything else maxed out, and selected. Visible range hits really hard >25 km here. (this is the biggest hitter, I guess it's to be expected since this increases the area drawn) Max clouds in loop > 0.3-0.4 of the slider (I'd guess about 200 km ?) (too bad the sliders don't display the actual value somewhere :( ) (with the visible range to the minimum: max clouds in loop has very mild adverse effects when increased) Also massive effects where noticed when disabling any of the buffering options, or lowering their value. (I guess system ram helps here) Back to the efficiency thingy, clouds further out (>20 km ?) should really be big boxes, as it's not worth it do draw them one by one, don't know how to solve this but I guess we could come up with an idea that's both visually pleasing and efficient to draw. One thing i'm thinking, is that the range animation drawback can be overcome by doing it in your code, like selecting the big box version for clouds that are a certain range out from the POV? (iterations in the nasal code seem to work pretty fast, it's just the gpu cannot keep up with them) HTH Emilian ------------------------------------------------------------------------------ Enable your software for Intel(R) Active Management Technology to meet the growing manageability and security demands of your customers.
