Well, sorry to "dissapoint" ;) you, but with everything converted to .dds (with pregenerated mipmaps), there's a HUGE improvement in performance. Now I can have everything maxed out, sure you see some redraw, but there's a very small performance hit when that happens. With "conservative" settings, once evrything is loaded there's almost no noticeable impact when rotating the view anymore. Almost same conditions as before. Almost, because I've done the tests with the lowpressure tile, and not with creating a custom setting in the Local weather dialogue. conversion done with : nvcompress -alpha -bc3 -repeat file.png file.dds (I'm thinking you have to specify -alpha if the source has an alpha channel, maybe there's some optimisation at work there, also pregenerated mipmaps help) size of all rgb textures is 43.5 MB size of all dds textures is 38.8 MB , so size on disk is a nonissue.. sure in some cases it might increase dramatically, but here it isn't the case. Off to fly the electra in some tropical thunderstorm :P.
