If you use default settings, you're comparing 20 km visibility with 35 km - that's 400 km^2 vs 1225 km^2 of cloud covered scene, or a factor 3. If you place the same number of clouds, I guess the fact that I use sometimes ~4 times higher texture resolution is bound to show. You possibly initially saw higher framerates around TNCM because Local Weather doesn't place many convective clouds over open water. I decided that a fair comparison is: Same scenery, same visibility, same cloud visibility, same cloud coverage in oktas, no wind drift. Under these conditions, local weather was 10% slower for a Cumulus layer in my tests. If you ask for overcast skies, than Local Weather is dramatically faster (the default clouds for me are unable to even render a decent 6/8 cover, and with the densest coverage I can get I get single digit framerates while passing through the layer - that's a factor 3 or more slower than Local Weather where I routinely get 20+ fps in rainy overcast conditions, more above the layer where the terrain isn't visible ). If you fly supersonic, then you're not dominated by rendering but by loading/unloading... and so on. So it's not clear to me what your standard of comparison is, and it's not a trivial question what it should be. But some cloud configurations (Coldfront, Tropical) are much slower than the standard 3d cloud Cumulus layer. But that's an apples/oranges comparison if you ask me. * Thorsten ------------------------------------------------------------------------------ Colocation vs. Managed Hosting A question and answer guide to determining the best fit for your organization - today and in the future. http://p.sf.net/sfu/internap-sfd2d _______________________________________________ Flightgear-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/flightgear-devel
